I am trying to install devise to my rails app, but all I am getting is this error message
rails g devise:install

I have tried searching and I get a lot of similar errors but for different operations. Nothing particularly helpful for this problem in particular. Is there anybody more skilled with Ruby who can help me? I am usually more of a Python guy...

EDIT 2
It occurred to me that it might be worth noting that I am using OSX. It also might be important to note that this is the DigitalOcean default Rails app that is loaded with their Nginx + Rails Image. I copied the project into a git repo on the server and then cloned that to my local machine.
Give this a try.
Run the command: gem pristine --all
And make sure to restart spring with spring stop && spring start
Do a clean install on your ruby and gems
rvm remove 2.2.3
rvm install 2.2.3
rvm use 2.2.3
gem install bundler
