Question

I’ve decided to get rid of rvm, and I’m having trouble compiling a gem with my new version of ruby 1.9.2. The gem requires 1.9.2, I have it, yet says it can’t install without, so the error messages makes no sense.

How can I explicitly tell the gem to compile with said version of ruby?

Gem::InstallError: linecache19 requires Ruby version >= 1.9.2.
An error occured while installing linecache19 (0.5.12), and Bundler cannot continue.
Make sure that `gem install linecache19 -v '0.5.12'` succeeds before bundling.
 apps2 ~/projects/sms/apps2/apps2_admin $ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.8.0]
 apps2 ~/projects/sms/apps2/apps2_admin $ which ruby
/usr/local/bin/ruby

I had the same issue (linecache19 hangs forever/indefinitely) when using rbenv on OS X Lion. I found the solution was to install Ruby with OpenSSL option, like this:

rbenv install 1.9.2-p290 --with-openssl-dir=/usr/local
rbenv rehash
rbenv global 1.9.2-p290

Now, you can run or bundle this and it’ll install fine:

gem install ruby-debug19

Hope that helps someone.
