I recently followed some instructions with RVM to install ruby-debug, and I think this might cause some problems. The link in which I found the instructions is here: http://beginrescueend.com/support/troubleshooting/
The commands I used to install are as follows:
$ rvm reinstall 1.9.3 --patch debug --force-autoconf
$ gem install ruby-debug19 -- --with-ruby-include="${MY_RUBY_HOME/rubies/src}"
Now, when I try to start the rails server, I get the following error:
./bundler_stubs/rails:13:in `require': no such file to load
from ./bundler_stubs/rails:13
This SO question made me believe that I had more than one version of the rails installed: there is no such file to load - rubygems (LoadError)
However, when I run which -a ruby, as the selected answer suggests, I get only /usr/bin/ruby. Any thoughts on what to do here?
