Rails -v saying wrong rails version on Mac OSX

Question

I've been trying to uninstall rails because it was on 4.1.0.rc1 and I wanted 4.0.0, so I ran ``` gem uninstall rails -v 4.1.0.rc1 ``` And it said it was uninstalled successfully but typing ``` rails -v ``` still gives me 4.1.0.rc1 I tried running ``` gem cleanup ``` but it still is giving me the wrong version, I've quit the terminal and opened it back up and everything and am still getting the wrong version. I just want to make sure that I am using the right version and everything is running smoothly. I've only been recently getting into ruby and learning how to install things in the terminal (I'm a recent mac convert) so all this stuff kind of wigs me out.

Accepted Answer

Look at the gemfile in your project. It should have this line ``` gem 'rails', '4.0.0' ``` Go to your projects directory and run ``` rails -v ``` This should return ``` Rails 4.0.0 ``` If you do a rails -v outside any rails folder it show the newest version you have. But , inside a rails project folder it uses the version defined in the gem file. When you greate a new rails project you can run ``` rails _<*version*>_ new ``` in the case of 4.0.0 ``` rails _4.0.0_ new myapp ``` This will return the rails versions you have ``` gem list | grep rails ``` if this returns ``` rails (4.0.3, 4.0.0, 3.2.12) ``` and you run ``` gem uninstall railties -v 4.0.3 ``` you go to back to rails 4.0.0 on the global system. But again in each rails project you be at whatever version that's specified in the gemfile.
