Error when running rails command (server, generate model, console, generate controller)

Question

Im running into a weird error whenever I invoke rails g model, or rails s. Application has been running fine and just noticed it now that I want to add a new Model.

Here's the stack trace for running rails g model my_model name:string, rails c and rails g controller test_controller:

Does the problem seem to be with the version of rails I'm using? I haven't made any changes so it's weird it's failing right now.

Appreciate your help.

UPDATE

I'm using 3.2.13 and ruby 1.9.2p290

UPDATE #2

Trying these commands on other projects on the same machine and user yield no error...

Please help! :(

Answer 1

Found the issue, there was a missing ENV variable in development, which was being parsed by URI.parse, and was sent nil, which caused the error.
