Rvm Install For Mac
Mar 22, 2012. This tutorial was last updated on May 10, 2018. NEW: My can automate the whole setup for you. After following many outdated and incomplete instructions for setting up a web development environment on a Mac (back in March 2012), and spending a lot of time finding solutions to the problems I encountered along the way, I decided to put together this detailed tutorial. Over time, as tools have improved, and with new releases of OS X, I've updated this tutorial.
With Sierra, El Capitan, Yosemite and Mavericks, setting up a development environment on a Mac with Apple's standalone Command Line Tools, Homebrew, Git, RVM, Ruby, and Rails is a fairly stress-free process that's no longer fraught with the issues from two years ago. In fact, the whole process can now be automated via the that I wrote for you. Whether you use my script that does everything for you, or set everything up manually, it's best that you start with a clean installation of OS X.
If you've already tried to install a development environment, I can't guarantee that you won't run into any issues. Certain tools used in this tutorial might not be compatible with whatever you might have installed. For example, RVM is not compatible with rbenv, and MacPorts is not compatible with Homebrew. Click on your OS X version below to get started:. Historical Background Up until February 2012, the only way you could get the Command Line Tools required for web development was via the full Xcode package, which is almost 2 GB in size. Since then, Apple started offering the Command Line Tools (CLT) as a separate, much smaller download (118MB), which benefits those who don't plan on writing Mac or iOS apps.
There is also a third-party option, the by Kenneth Reitz, that supports both Snow Leopard and Lion. However, it is not updated as often as the official Apple tools, and I personally ran into issues with it on Lion. When I tried Apple's CLT for Lion back in March 2012, they weren't compatible with Homebrew: Warning: Your Xcode is configured with an invalid path.
You should change it to the correct path. Please note that there is no correct path at this time if you have.only. installed the Command Line Tools for Xcode. As of August 6, 2012, the issue above is no longer present with the latest CLT for Mountain Lion, and I believe that's the case on Lion as well, but I haven't confirmed that yet. Until I do, I recommend getting the CLT from Xcode if you're on Lion, as explained in this tutorial. The Easy Way for Sierra, El Capitan, Yosemite and Mavericks I've written an open source script that can, including configuring your Mac to work with GitHub. If you prefer to do everything manually, start with Step 1 below.
Step 1: Download and Install the Command Line Tools Installing the standalone Command Line Tools on Sierra, El Capitan, Yosemite or Mavericks Most of the work you'll be doing in this tutorial will be in the 'Terminal' application. The easiest way to open an application in OS X is to search for it via.
The default keyboard shortcut for invoking Spotlight is command-Space. Once Spotlight is up, just start typing the first few letters of the app you are looking for, and once it appears, select it, and press return to launch it. See the animated GIF below for an example: Inside the Terminal window, copy and paste (or type) the following command, and press the return key on your keyboard: xcode-select -install You should see the pop up below on your screen.
Click Install when it appears. Click Agree when the License Agreement appears: Your computer will then attempt to find the software, and then will start downloading it.
The following popup will appear: Once the software is installed, click Done. You're now ready to go to. Installing the standalone Command Line Tools on Mountain Lion Go to and sign in with your Apple ID (the same one you use for iTunes and app purchases). Search for 'command line tools' (in the search field on the left), then click on the latest version of 'Command Line Tools (OS X Mountain Lion) for Xcode,' and click on the the.dmg link to download it.
Once the.dmg has finished downloading, double-click on it (if it didn't already open automatically). This will mount the disk image and open a window in your Finder that looks like this: Double-click on the 'Command Line Tools (Mountain Lion).mpkg' installer and go through the installation.
Once the CLT are installed, launch the 'Terminal' application via Spotlight (as explained in ), then go to. Installing Xcode on Lion Click on this link to, then click on 'View in Mac App Store.' It should automatically launch the 'App Store' app on your Mac and take you the Xcode page. Click on the 'Free' button, then click on 'Install App.' Once the installation is complete, go to your Applications folder and double-click on Xcode, then install any required components if asked to.
Go to Xcode's Preferences via the menu bar, or by pressing the command and comma keys. Click on the 'Downloads' icon, then click on the 'Install' button next to 'Command Line Tools.' When prompted to log in, you should be able to use the same email and password you use for iTunes and app purchases. Once the Command Line Tools are installed, quit Xcode, launch the 'Terminal' application via Spotlight (as explained in ), then go to. IMPORTANT NOTE: If you upgraded to Mountain Lion from Lion, and you already had Xcode installed on Lion, and you updated to Xcode 4.4 and updated the Command Line Tools while still on Lion, you will have to go back to Xcode and download the Command Line Tools again after upgrading to Mountain Lion. Snow Leopard Instructions UPDATE: A kind reader (P. Martin) pointed out that the Xcode 4.2 download for Snow Leopard is only available to those registered in the $99/year developer program.
I confirmed that the latest version of Xcode for Snow Leopard available to me while signed in with a free account is 3.2.6. I have not tested this setup with Xcode 3.2.6, but I would love to hear from you if you have.
Rvm Install For Mac Pro
Otherwise, I recommend that you upgrade to a newer version of OS X. Go to and sign in with your Apple ID (the same one you use for iTunes and app purchases). If you are part of the $99/year Apple developer program, search for 'xcode 4.2' (in the search field on the left), then click on 'Xcode 4.2 for Snow Leopard,' and click on the.dmg link to download it. Otherwise, search for 'xcode 3.2', then click on 'Xcode 3.2.6 and iOS SDK 4.3 for Snow Leopard,' and click on the.dmg link to download it. As mentioned at the beginning of this section, I have not tested this tutorial with Xcode 3.2.6, so I would recommend that you upgrade to a newer version of OS X.
Once the.dmg has finished downloading, it should automatically mount the disk image and open a window in your Finder that looks like this: Double-click on the 'Xcode' package installer. Once the installer launches, make sure all the checkboxes are checked, as shown in the screenshot below: Click 'Continue,' and go through the rest of the installation. If the installation fails, quit the installer, then run Software Update and install any updates that it finds. If no new updates are available, restart your computer and try installing Xcode again. Once Xcode is successfully installed, you can move on to. Step 2: Install Homebrew, 'the missing package manager for OS X,' allows you to easily install hundreds of open-source tools.
The full instructions are available on the, but you should only need to run the command that's listed at the top of the: ruby -e '$(curl -fsSL Note that the command listed on the Homebrew site could change, so please make sure that what I have listed above is the same. If it isn't, please let me know and I'll update it. Copy and paste the command into your Terminal window, press return, then follow the instructions when prompted, as highlighted in the screenshot below. Note that Terminal does not provide visual feedback when you type your password. Just type it slowly and press return. Once the installation is successful, run the following command: brew doctor If you get Your system is ready to brew, you can move on to.
Otherwise, go to the section to learn how to fix errors and warnings you might run into. Step 3: Install Git is the of choice among many web developers. With Homebrew, installing Git is as easy as this: brew update brew install git Since we just installed Homebrew, we could have skipped brew update, but it's a good habit to run it before installing anything with Homebrew because Homebrew is updated regularly. To verify: git -version You should get git version 2.3.1 or later. Run brew doctor to make sure everything is still working. If your system is ready to brew, you can move on to.
Step 4: Configure Git with GitHub for Mac Download, install, and launch. If you don't have a GitHub account, click on the Sign Up at GitHub.com link in the app, then come back to the app to complete the setup. I highly recommend that you turn on for your GitHub account. Follow these steps to set up GitHub for Mac when you first launch it:. Click Continue. Enter your username and password, then click Sign In.
Expect us to push the boundaries of individual and team productivity with capabilities like IntelliCode, where Visual Studio can use Azure to train and deliver AI-powered assistance into the IDE. As before, Visual Studio 2019 previews will install side by side with Visual Studio 2017. Microsoft announces visual studio 2017 rc visual studio for mac pro. Expect more and better refactorings, better navigation, more capabilities in the debugger, faster solution load, and faster builds. This is great for trying out new functionality without messing with your production workflow. But also expect us to continue to explore how connected capabilities like Live Share can enable developers to collaborate in real time from across the world and how we can make cloud scenarios like working with online source repositories more seamless.
Enter your two-factor authentication code (if you have it turned on). Click Continue.
Enter an email address that you want to be attached to your commits. It doesn't have to be your real email address, but if you leave this blank, Git will nag you about it every time you commit. Click Continue. Click Done To see this setup in action, go to the 1:26 mark in the I created to showcase my. Step 5: Install RVM with the latest Ruby (2.2.0) and Rails (4.2.0) stands for Ruby Version Manager, and is one of the most popular tools that allow you to install and manage multiple versions of Ruby and Rails on the same computer.
RVM has come a long way since I originally published this tutorial. As of March 30, 2013, you can now install the latest RVM, Ruby, and Rails in one step. However, because RVM installs documentation for every gem that Rails depends on, which takes forever, I recommend disabling documentation first: echo 'gem: -no-document' /.gemrc Now you can install everything with one command. If you're not interested in Rails, just replace -rails with -ruby in the command below: curl -L bash -s stable -auto-dotfiles -autolibs=enable -rails Read the to see all the different options you can use. This will take a few minutes, and once it's done, quit and relaunch Terminal, then run this command: type rvm head -1 If you get rvm is a function, that means RVM was successfully installed. If not, go to the section.
To make sure the latest versions of RVM, Ruby and Rails were installed, run the commands below: For RVM rvm -v You should get rvm 1.26.10 or higher. For Ruby ruby -v You should get ruby 2.2.0 or higher. If you get dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib, that means something is wrong with the binary version of the latest Ruby. To fix it, reinstall your desired Ruby version by disabling the binary: rvm reinstall 2.2.0 -disable-binary For Rails rails -v You should get Rails 4.2.0 or higher. To make sure your system is still ready to brew: brew doctor If everything went well, you're done! Your machine is now set up with the basic tools for web development. If you got any value out of my tutorial, I have more time-saving tips and tricks for you in my.
Next Steps Once you start hacking away on your computer, you will most likely need to install more tools with Homebrew. Before you do, remember to always run brew update and brew doctor to make sure your system is still ready to brew. To upgrade your existing packages, run brew upgrade. If you installed the full Xcode package, remember that when you update it via the Mac App Store, you might also need to update the Command Line Tools via Xcode's Preferences. If you installed the standalone CLT, I recommend checking for a new version once a month or so. If you followed this tutorial because you're interested in Rails development, I recommend visiting Daniel Kehoe's excellent.
If you want to install another version of Ruby besides 2.2.0, follow the instructions below. Installing other versions of Ruby, such as 2.1.5 Before you install a version of Ruby with RVM, you should make sure you have the latest version of RVM: rvm get stable -autolibs=enable -auto-dotfiles Then run: rvm install 2.1.5 To see all the versions of Ruby installed via RVM: rvm list rubies This output also lets you know which version is the default and which one is the current one in use. To use a specific version (2.2.0 in the example below) and also set it as the default version for new shell sessions: rvm use 2.2.0 -default To verify: ruby -v The version should match that of the current Ruby in use. Troubleshooting Homebrew In many cases, Homebrew will provide helpful instructions for dealing with warnings and errors, and I usually follow those instructions. I've tried to cover the most common sources of warnings and errors.
If you run into an issue I haven't mentioned, try looking it up in the, or Google the error message. If that doesn't help, contact me and I'll do my best to help you. After you fix each issue, run brew doctor until you get Your system is ready to brew. If you get Warning: /usr/bin occurs before /usr/local/bin, run the command below (as recommended by Homebrew), and quit and relaunch Terminal: echo 'export PATH='/usr/local/bin:$PATH' /.bashprofile This command takes everything between the single quotes and adds it ( ) to a file called.bashprofile in your user's root directory ( /).
Every time you open a new Terminal window or tab,.bashprofile is called. The export PATH line tells your system to look in /usr/local/bin first, since that's where Homebrew installs tools. If you get Warning: Experimental support for using Xcode without the 'Command Line Tools', you probably upgraded from Lion to Mountain Lion but didn't reinstall the Command Line Tools. See the in Step 1. If you get Error: No such file or directory - /usr/local/Cellar, run the following command, which creates the /usr/local/Cellar directory: sudo mkdir /usr/local/Cellar sudo allows you to run commands as a user with higher access rights, which is why it prompts you for your password, and mkdir stands for 'make directory.' If you get /usr/local/etc isn't writable or Cannot write to /usr/local/Cellar or if it complains that any directories inside /usr/local aren't writable, fix it with this command: sudo chown -R `whoami` /usr/local This makes you the owner of the /usr/local directory, in addition to all nested directories.
Chown stands for 'change owner,' the -R flag applies this to all nested files and directories, and whoami is a variable that represents your OS X username. You should copy and paste the command above as is. To learn more about any Unix command, type man (for 'manual'), followed by the command. For example: man chown If a manual is longer than a page long, it will display a: at the end to signify there is more to read. To display one additional line at a time, press return. To display an additional page at a time, press the space bar.
To quit at any time, press q. If you get Warning: Unbrewed dylibs were found in /usr/local/lib, or a warning about any type of unbrewed files or static libraries, you may need to delete them as suggested by Homebrew (unless you put them there on purpose, which is unlikely). You'll have to delete each file it complains about one by one with the rm command. For example, to remove a file called libgd.2.0.0.dylib from /usr/local/lib, you would run this command: rm /usr/local/lib/libgd.2.0.0.dylib If you get Warning: Python is installed at /Library/Frameworks/Python.framework, or Warning: 'config' scripts exist outside your system or Homebrew directories related to Python, it most likely means you installed Python with a tool other than Homebrew. If you think you might need this version of Python, then just ignore those warnings.
Otherwise, run the command below to remove that version of Python, but. Sudo rm -rf /Library/Frameworks/Python.framework If you're on Lion, you might get this: Warning: Your Xcode is configured with an invalid path. You should change it to the correct path. Please note that there is no correct path at this time if you have.only. installed the Command Line Tools for Xcode. If your Xcode is pre-4.3 or you installed the whole of Xcode 4.3 then one of these is (probably) what you want: sudo xcode-select -switch /Developer sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer DO NOT SET / OR EVERYTHING BREAKS!
This should fix it: sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer Run brew doctor to verify. Your system should be ready to brew now. In some cases, brew doctor might show you this warning: Warning: Some keg-only formula are linked into the Cellar. Linking a keg-only formula, such as gettext, into the cellar with `brew link ` will cause other formulae to detect them during the `./configure` step. This may cause problems when compiling those other formulae. Binaries provided by keg-only formulae may override system binaries with other strange results.
You may wish to `brew unlink` these brews: libxml2 Homebrew messages are generally very helpful and they let you know exactly what to do. In this case, it is telling you to fix the linking issue by running brew unlink, followed by the tools (or 'brews') that need to be unlinked. Here, there is only one tool that needs to be unlinked.
Therefore, you should run this command: brew unlink libxml2 If it listed more than one tool, you would add them to the command separated by a space, like so: brew unlink tool1 tool2 tool3 Run brew doctor once more, and you should be ready to brew now. RVM If you're installing RVM on a machine that has gpg installed (which won't be the case on a new Mac), you will get a GPG signature verification failed error. Make sure to follow the instructions in the error message. At the time of this writing, you will need to run the command below to download the signatures, after which you can go back to to install RVM. Gpg -keyserver hkp://keys.gnupg.net -recv-keys D39DC0E3 How to load RVM into your shell session as a function Run this command: echo ' -s '$HOME/.rvm/scripts/rvm' &&.
'$HOME/.rvm/scripts/rvm' # Load RVM function' /.bashprofile Now that.bashprofile has been modified, it needs to be reloaded. For initial RVM installations, the preferred way to do this is to quit and relaunch Terminal. Otherwise, you can use the following command: source /.bashprofile If all went well, you should see rvm is a function after you run this command: type rvm head -1 Previous Notes Installing Ruby on Snow Leopard and Lion is presumably as easy as on Mountain Lion, but I haven't been able to verify that. The instructions below are based on my experience in 2012. I've left them here for reference but I'm not sure if they still apply.
For example, running rvm requirements used to provide instructions specific to your environment, but now it tries to install all the requirements for you. The screenshots below are examples of the kind of output rvm requirements would show. One is for Snow Leopard 10.6.8 with Xcode 4.2, and the other for Mountain Lion 10.8 with no Xcode: According to the requirements, we must first install libksba. This applies to Snow Leopard, Lion and Mountain Lion. We can do that easily with Homebrew, but first we should make sure it is up to date: brew update brew install libksba Since Homebrew is updated regularly, it's advisable to run brew update before installing anything with Homebrew.
Now we're finally ready to install Ruby 1.9.3! If you're on Snow Leopard, you need to add a flag to the command (as specified in the RVM requirements): rvm install 1.9.3 -with-gcc=clang If you're on Lion, you need to install automake first: brew install automake rvm install 1.9.3 Otherwise, you will get this error when installing Ruby 1.9.3: rvm requires autoreconf to install the selected ruby interpreter however autoreconf was not found in the PATH. If you're on Mountain Lion 10.8.2 with Xcode 4.5, you will need to run these commands first: brew update brew tap homebrew/dupes brew install autoconf automake apple-gcc42 rvm pkg install openssl rvm install 1.9.3 (or `rvm reinstall all -force` in case you had already installed ruby) sudo ln -s /usr/local/bin/gcc-4.2 /usr/bin/gcc-4.2 The steps above are necessary for you to be able to install Ruby gems, such as Rails. Otherwise, you will run into errors such as these: ERROR: Failed to build gem native extension make: /usr/bin/gcc-4.2: No such file or directory Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers The compiler failed to generate an executable file You have to install development tools first.
