Only way you could do it is to add two files to your application: .ruby-version
and .ruby-gemset
and add 2.1.1
in the .ruby-version
file and rails4
in the .ruby-gemset
file.
You can also do this on your command line with:
echo 2.1.1 > .ruby-version
and
echo rails4 > .ruby-gemset
And that will create the files for you with the version 2.1.1 and the gemset rails4
So whenever you open a new terminal, rvm will use ruby 2.1.1 and gemset rails 4
