I'm running into issues trying to install Rails on OS X Lion using RVM.
So far, I have done the following:
rvm install 1.8.7
. Note: I need to be using 1.8.7 and not 1.9.2.rvm 1.8.7
.rvm gemset create rails3
.rvm use 1.8.7@rails3
.To install Rails I ran the command gem install rails
but I got the following error:
/Users/m/.rvm/rubies/ruby-1.8.7-p334/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
The same error happens when trying to run any gem command so I don't think it's really a problem with Rails.
Judging by the links below, I don't seem to be the only person having this issue:

Fixed it!
The answer was actually on one of the links I posted above. Before installing a version of ruby (rvm install 1.8.7) I needed to run "export CC=/usr/bin/gcc-4.2
". With that in place, everything ran smoothly.
If you don't want to have CC
permanently exported, you can do CC=/usr/bin/gcc-4.2 rvm install 1.8.7
If you have already installed ruby 1.8.7. Just do CC=/usr/bin/gcc-4.2 rvm reinstall 1.8.7
If you have installed Xcode 4.2, it actually doesn't install non-LLVM gcc anymore, so you have to add it. For some reason downgrading to 4.1 after you've installed 4.2 doesn't work correctly (at least it didn't for me and others have had similar issues).
After quite a bit of thrashing, this is what finally worked for me:
Close any open terminal windows, open a fresh one and
rvm remove ree
export CC=/usr/bin/gcc-4.2
rvm install ree
This worked for me with rvm 1.8.6, OS X 10.7.2 and gcc-4.2 version 4.2.1 (Apple build 5666).
If you have already installed Xcode 4.1, resist the urge to upgrade to 4.2 and you should be okay.
If that still doesn't work add --force. So this becomes:
CC=/usr/bin/gcc-4.2 rvm install ruby-1.8.7 --force
Make sure that you remove 1.8.7 if you already installed it before using "export CC=/usr/bin/gcc-4.2
" by doing "rvm remove 1.8.7
"
I had the same issue on my system. I installed the Xcode command line tools from Apple which ships with LLVM compiler and without an LLVM free one.
Ruby 1.8.7 won't work with an LLVM compiler not even with CC=clang
, so installing an LLVM free gcc solves the problem.
There are multiple options listed here:
https://github.com/mxcl/homebrew/wiki/Custom-GCC-and-cross-compilers
Long story short, install GCC v4.2 with Homebrew:
brew install https://raw.github.com/Homebrew/homebrew-dupes/master/apple-gcc42.rb
and then install ruby 1.8.7:
CC=gcc-4.2 rvm install 1.8.7
Check which version of gcc you have like this:
ls -Al `which gcc-4.2`
I followed the instructions here: http://robots.thoughtbot.com/post/27985816073/the-hitchhikers-guide-to-riding-a-mountain-lion
brew update
brew tap homebrew/dupes
brew install apple-gcc42
Then reinstall:
Check again what your path to gcc is (to use for CC=):
ls -Al `which gcc-4.2`
(optional) You can set this in your .bashrc for example:
export CC=/usr/bin/gcc-4.2
(optional) remove any old version of ruby
rvm remove 1.8.7
Then:
CC=/usr/local/bin/gcc-4.2 rvm --verify-downloads 1 reinstall 1.8.7-p357 --without-tcl --without-tk
or if you have set CC in your profile
rvm --verify-downloads 1 reinstall 1.8.7-p357 --without-tcl --without-tk
Note the flags on the rvm install. I had trouble verifying the checksum on the ftp server and some problems with tck and what not. You may be able to omit those flags.
Also: you might need to remove an old version of your gemset:
rvm gemset delete <gemset>
Then
gem install bundler
bundle install
Hope this helps.
Using macport and ruby-1.9.x version. I did successfully install rails with ruby gem.
Instead of "export CC=/usr/bin/gcc-4.2
" do "export CC=gcc
" (xCode 4.2.x should be installed).
I have same problem only for arch x86_64, when I comment line in my ~/.rvmrc
rvm_archflags="-arch x86_64"
Open a new terminal and tried to install ruby-1.8.7 again
rvm install 1.8.7
It was successful.
