RVM gem permissions error

$ gem install rails
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions into the /var/lib/gems/1.9.1 directory.


You missed to use ruby, you can do it with:

rvm use 1.9.3 --install

In case 1.9.3 was not installed, this command will also install it!

It also looks you are using Ubuntu, make sure you are not using RVM from Ubuntu package – that thing is broken! You can find instruction how to fix it here: StackOverflowLink
