Last week it all worked. I installed RubyMine, got my project checked out, got the RVM environment setup. Successfully ran console, mongrel, rake and generate tasks...
Today I can edit files, but anything I do that uses the external ruby fails with a method not found exception that looks like the error message below.
I can run everything from a terminal, so I know that RVM, Bundle, and rails are setup correctly.
The only thing I've done to change things (knowingly at least) is to change the run configuration for rake db:migrate to use a full stack trace.
The stack trace for rake and the output of the RubyMine Show Gem Environment are attached.
Thanks for your help!
