I need to do something with Ruby on Rails, so I have followed this guide to set up my development environment.
I used the RVM method to install Ruby, then I install Rails as shows in the guide. I run both ruby -v and rails -v and they give me the expected output, I do my stuff using rails and everything is ok.
Problem is that when I restart my machine nor Ruby or Rails is installed, I have to install them back everytime I restart. Do you know what could be the reason?
Are you sure that its not just RVM not being started ?
Check .rvm/scripts/rvm exists in your home directory.
If it does, then its probably not being started, check in your .bashrc for lines below.
If they are not there you need to add the calls to initialise RVM in your .bashrc by running the following command:
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"' >> ~/.bashrc
Based on instructions from: http://sirupsen.com/get-started-right-with-rvm/
