pip: no module named _internal

Question

I have a problem when I try to use pip in any way. I\'m using Ubuntu 16.04.4

I should say that I\'ve used it already, and I never had any problem, but starting today

Answer 1

Are you using python2 or python3? The following command could be different!

1. use python3 -m pip --version to see if you have pip installed.
2. if yes, run python3 -m pip install --upgrade pip.
3. if no, run sudo apt-get install python3-pip, and do it again.
