Why doesn't Rails work in the second terminal window?

I want to run the rails server in one terminal window and work in another terminal window, but the second window does not work, although I would expect the two windows to work the same way.

When I print rails (much smaller than rails s , etc.) in this second window, I get this error:

 Could not find jquery-rails-2.0.2 in any of the sources Run 'bundle install' to install missing gems.

My understanding is that bundle install should not be necessary (as it was already taken care of in the first window, and everything works fine), and I made sure that everything is as it should be, with which ruby and rvm use <my gemset> etc. In the second terminal window, I assure that I am using the appropriate version of Ruby and gemset, but it does not work.

Meanwhile, the original terminal window continues to work exactly as it should - I just need to exit the Rails server in order to continue working, which is annoying.

Is there something painfully obvious here that I don't understand about working in the second terminal window? I would not expect many settings to be required.

Despite my efforts to make sure they did, the gemsets between the two Terminal windows did not match. This was discovered using a gem list and comparing two outputs.

If someone is still trying to use:

 rvm use 2.1.0

2.1.0 is your ruby ​​version.
