Stuck with a gem that just wont uninstall
Yesterday i was updating all my ruby gems. During the update a got disturbed by something so i did not pay attention what gems got updated.
This morning i found my current app not starting up.
This is how i solved it
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | #script/server => Booting Mongrel (use 'script/server webrick' to force WEBrick) => Rails application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server ** Starting Mongrel listening at 0.0.0.0:3000 ** Starting Rails with development environment... ** Rails loaded. ** Loading any Rails specific GemPlugins Exiting /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- /opt/local/lib/ruby/gems/1.8/gems/mongrel-1.1-java/lib/mongrel/init.rb (MissingSourceFile) from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /opt/local/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/active_support/dependencies.rb:495:in `require' from /opt/local/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/active_support/dependencies.rb:342:in `new_constants_in' from /opt/local/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/active_support/dependencies.rb:495:in `require' from /opt/local/lib/ruby/gems/1.8/gems/gem_plugin-0.2.3/lib/gem_plugin.rb:134:in `load' from /opt/local/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:184:in `each' from /opt/local/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:184:in `each' from /opt/local/lib/ruby/gems/1.8/gems/gem_plugin-0.2.3/lib/gem_plugin.rb:112:in `load' ... 21 levels... from /opt/local/lib/ruby/gems/1.8/gems/rails-1.2.5/lib/commands/server.rb:39 from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require' from /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from script/server:3` |
Ok, so now what? I know i do not run java. Not just yet.
My update last night must have installed a mongrel-1.1-java, no biggy i just uninstall.
1 2 3 4 5 6 7 8 9 10 11 12 13 | gem uninstall mongrel Select gem to uninstall: 1. mongrel-1.0.1 2. mongrel-1.0.2 3. mongrel-1.1 4. mongrel-1.1-java 5. mongrel-1.1.1 6. mongrel-1.1.4 7. All versions > 4 INFO: In order to remove mongrel, please execute: gem uninstall mongrel --install-dir=/opt/local/lib/ruby/gems/1.8 |
If i add the install dir i get the same result. Just for fun i try to delete the ruby-java-gem folder -> /opt/local/lib/ruby/gems/1.8/gems/mongrel-1.1-jruby/
But still the same error and gem still think the gem is installed.
This became my solution
For each installed gem there is a gemspec file that holds information about the gem. After deleting the gemspec for ruby-1.1-java everything went back to normal.
1 | sudo rm /opt/local/lib/ruby/gems/1.8/specifications/mongrel-1.1.1.gemspec |
Hope this can help someone 
Great, thanks! I had the same bug since a few days. Your solution is not very elegant but it worked out much better than everything I tried before…

I know. It’s dirty but i couldn’t find a better solution at the moment.
I’m glad it helped!
Cheers!

I had the same problem, but my gem specs weren’t in the same place. To find out where they were installed:
gem list -d mongrel
Thanks!
