Unable to create Ruby on Rails projects in Rubymine

• Suddenly I'm not able to create new projects properly. When I create a new rails project with Rubymine it creates my files into a subfolder called 3.0.9. I'm also unable to start my project. The error I get is:

RubyMine Gem Manager

RubyMine has detected that some of the gems required for 'testproject' are not installed

Install missing gems

So I click on "Install missing gems" I get the error:

Following gems were not installed:

xaws-s3x: No gem satisfying dependency found in remote gem repositories

• If I try to start the project it says:

Error running Development: testproject: Rails server launcher '/home/laptop/RubymineProjects/testproject/script/rails' wasn't found in project

• If I try to put a rails server launcher in the folder script from another project it gives me a bunch of other errors saying:

WARN TCPServer Error: Address开发者_开发百科 already in use - bind(2)

/usr/lib/ruby/1.8/webrick/utils.rb:73:in `initialize': Address already in use - bind(2) (Errno::EADDRINUSE)

Sidenote:

I'm using Ubuntu and it all worked fine a couple of days ago when I was creating projects.

My understanding is that the server process, for whatever reason wasn't shut-down properly and so is still hanging on the port that it started on. You'll have to kill this, in order restart it again. Assuming that it is consuming the port 3000 (the default port), in Ubuntu you can find its process-id and kill it by the below command:

lsof -i tcp:3000 -Fp|tr -d p | xargs kill -9

Hope it helps!
