-bash: __git_ps1: command not found

Question

I tried to install Ruby 2.0. My command line urped and now looks like the following:

-bash: __git_ps1: command not found
[11:58:28][whatever@whatever ~]$ 
         


        

Answer 1

I solved it simply using

sudo apt install git

This appears because git is not installed and therefore the environment variable is not defined.
