Cannot Install Ruby 1.9.3 on a Clean Lion Install

Cannot install Ruby 1.9.3 on a clean Lion Install

I solved the problem. RVM wasn't recognizing the readline installed. Funny how readline manages to screw up so many people's installs.

This command points rvm toward the right readline location

rvm install 1.9.3 --with-gcc=clang --with-readline-dir=$rvm_path/usr

Can't install Ruby under Lion with RVM – GCC issues

This answer was edited multiple times and now contains several alternative solutions. Try the simple “Edit 3” solution first.

Ruby 1.9.3-p125 and later have official support for clang, so if you are installing such a version you should not need GCC. If you’re installing an older version of Ruby, read on.

To compile Ruby with GCC, you need a non-LLVM version of GCC, which is no longer included with Xcode 4.2. Install it yourself (or downgrade to Xcode 4.1 temporarily), then do CC=/usr/local/bin/gcc-4.2 rvm install 1.9.3 --enable-shared (substituting the path to your non-LLVM gcc).

Edit: https://github.com/kennethreitz/osx-gcc-installer/downloads may help for installing GCC. There is also some info available by running rvm requirements.

Edit 2: For an easier solution, you can try adding --with-gcc=clang to the arguments to configure for Ruby to use clang instead of GCC.

Edit 3: rvm install 1.9.3 --with-gcc=clang does that for you.

Note: With current versions of Xcode you need to install the command-line tools separately from the Xcode menu -> Preferences -> Downloads -> Components. This is a pre-requisite for doing any compiling with Xcode on the command-line, not just Ruby.

Note 2: If something doesn't work after following the steps, try doing a reboot or re-login to ensure that the environment gets set correctly.

Note 3: Ruby versions prior to 1.9.3-p125 may not always be fully compatible with clang, so test your software thoroughly if using the “edit 3” solution in a production environment.

How can I install Ruby 1.9.3 in Mac OS X Lion?

Try using the clang compiler instead of the default:

rvm install 1.9.3 --with-gcc=clang

Trouble installing ruby 1.9.3 because of a configuration issue

First goal should be to get the app back up running.

Therefore I would suggest to reset your app's configuration to the last working stand.
If this is not possible, please install ruby using rvm with the --with-gg=clang-option like this:

rvm install 1.9.3 --with-gcc=clang

Then use the installed ruby version by listing all installed rubies (running rvm list) and choosing the 1.9.3 version provided (e.g. 1.9.3-p448) with the following command:

rvm --default use 1.9.3-p484

Please update your Gemfile with the ruby '1.9.3-p484' line and make sure, you're in the login shell (to change to it, use /bin/bash --login). After that your rvm commands should work again.

Lion ate my RVM and now I can't install Ruby

After you install Lion, you have to re-install Xcode/Developer tools. It is available from the app store.

Make error installing Ruby 1.9.2 with RVM and Readline under OSX Lion

I had a very similar issue. I eventually found that adding this to my .bash_profile stopped my initial make errors:

export ARCHFLAGS="-arch x86_64"

Also from the command line run the following:

brew install readline
brew link readline
brew install libxml2
brew link libxml2

Then when you install ruby use this command:

rvm install 1.9.2 -C --with-readline-dir=/usr/local/Cellar/readline/6.2.1/ --with-libxml2-dir=/usr/local/Cellar/xml2/2.7.8

Hope that helps

Installing Ruby 1.9.3 Troubles with Clang

Refer to this answer.

Even though both ruby-1.9.3-p125 and ruby-1.9.3-p194 some support for clang, installing Ruby with clang is generally not recommended.

(Note: I had to accept edit proposal first, then edit. Thank you very much for contribution.)

Make error installing Ruby 1.9.2 via rvm OSX Lion 10.7.2 XCode 4.2

This error has been fixed in 1.9.2-head ... so just

rvm install 1.9.2-head && rvm use 1.9.2-head --default

I'm finding 1.9.3 isn't compatible with a lot of the libraries I use yet. This works with Xcode 4.2.
