Interesting issue

I'm upto the point where I'm creating the friendships models for user join tables.

Now comes the interesting part, so I run rails generate model Userfriendships

Then I get an error so I quickly check my version, rails -v and now I'm getting the following error whenever I type a command using rails -v for example. I currently have half a screen as the other half has been smashed across the floor.

Your help is greatly appreciated as I may start turning green at any second.

C:\Sites\treebook>rails -v                                                      
Looks like your app's ./bin/rails is a stub that was generated by Bundler.                                                                                      
In Rails 4, your app's bin/ directory contains executables that are versioned like any other source code, rather than stubs that are generated on demand.  Here's how to upgrade:    

  bundle config --delete bin    # Turn off Bundler's stub generator              
 rake rails:update:bin         # Use the new Rails 4 executables                
 git add bin          # Add bin/ to source control                                                                                                    

You may need to remove bin/ from your .gitignore as well.                                                                                                       

When you install a gem whose executable you want to use in your app,  generate it and add it to source control:  bundle binstubs some-gem-name        git add bin/new

Using bundle exec may solve this. (Gem::LoadError)
