Ubuntu 14.04.

So everything was working fine and I had my terminal open with two tabs - one tab had webbrick running on my sebcoles project, and the other tab I used to clone my english_teacher repo. It all downloaded fine and I changed into the directory.

I'll just paste everything here - it's all pretty clear:

andrew:projects$ cd pinteresting
RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore /home/andrew/projects/pinteresting/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

ruby-2.1.5 is not installed.
To install do: 'rvm install ruby-2.1.5'

andrew:pinteresting$ rvm install ruby-2.1.5

Warning, new version of rvm available '1.26.11', you are using older version '1.26.10'.
You can disable this warning with:    echo rvm_autoupdate_flag=0 >> ~/.rvmrc
You can enable  auto-update  with:    echo rvm_autoupdate_flag=2 >> ~/.rvmrc

So, basically I'm screwed at the moment - I can't do anything. Help!

I should add that everything still works fine in the first tab, but now I have to shut down my laptop. I expect that when I reboot this won't be the case anymore :-( – Yorkshireman

You have installed rvm but forget to install rails gem. Install it use:

gem install rails

Turns out I just had to run bundle install and everything was fine. However, for my pinteresting repo, which uses the paperclip gem, I had to run sudo apt-get install imagemagick in order to upload images in development.

Haven't dared commit anything new and push and deploy to heroku yet though. I think it should be fine though (touch wood).

I too had the same error. I forgot to switch to correct ruby version and correct gemset using rvm. That's it, I was able to sort this issue. 

$rvm list
$rvm use ruby version 
$rvm gemset use gemset-name
