After uninstalling and reinstalling Ruby and Rails many ways, why can't get I get it to be found?

For several days I have been struggling with a Rails app. I tried everything I could, asked some questions on SO and tried to gather all the information and tricks I could. Here's the summary:

Some days ago, when I ran rails s, I got the following, knowing I removed ruby-2.0.0-p0:

`require': dlopen(/Users/git/gitlab/vendor/bundle/ruby/2.0.0/gems/posix-spawn-0.3.6/lib/posix_spawn_ext.bundle, 9): Library not loaded: /home/.rvm/rubies/ruby-2.0.0-p0/lib/libruby.2.0.0.dylib (LoadError)
      Referenced from: /Users/git/gitlab/vendor/bundle/ruby/2.0.0/gems/posix-spawn-0.3.6/lib/posix_spawn_ext.bundle
      Reason: image not found - /Users/git/gitlab/vendor/bundle/ruby/2.0.0/gems/posix-spawn-0.3.6/lib/posix_spawn_ext.bundle

I was told on SO this could be related to RVM. I switched from RVM to rbenv, and I uninstalled/reinstalled Ruby (not the built-in OS X one) and Rails and got the same message when running rails s.

Then I uninstalled and deleted completely Macports and tried again with rbenv and got the same message.

I tried to symlink /home/.rvm/rubies/ruby-2.0.0-p0/lib/libruby.2.0.0.dylib to /usr/local, I got the same message.

I tried playing around with exporting DYLD_LIBRARY_PATH but I got the same message.

I uninstalled rbenv, Rails, and I returned to Macports and RVM, and I still get the same message.

Could some one help please?

I am using OS X.

ruby -v outputs ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin12.4.0] rails -v outputs Rails 3.2.13

I deleted ruby-2.0.0-p0.

Edit:

grep rvm ~/.bashrc outputs:

grep rvm ~/.bash_profile outputs:

Solution

  • you rails thinks it should use --deployment / or --path from bundler - it's the path to gems: /Users/git/gitlab/vendor/bundle/ruby/2.0.0/gems, unfortunately bundler is nto smart enough and does not handle properly changes in ruby, you need to remove whole directory rm -rf /Users/git/gitlab/vendor/bundle and bundle install again.

    I would recommend you stop using --deployment / or --path flags from bundler, remove the directories rm -rf /Users/git/gitlab/vendor/bundle, rm -rf /Users/git/gitlab/.bundle/ and install gems in gemset, this way this problem will not happen again.

    In case of capistrano deployments set this flags for bundler/capistrano:

    set :bundle_dir, ''
set :bundle_flags, '--system --quiet'

    to prevent using --deployment and --path flags with bundler.
