Error after upgrading pip: cannot import name 'main'

Question

Whenever I am trying to install any package using pip, I am getting this import error:

guru@guru-notebook:~$ pip3 install numpy
Traceback (most recent call l         


        

Answer 1

On Debian you will need to update apt first....

sudo apt-get update -qq
sudo apt-get install python-pip -qq
sudo pip install pip --upgrade --quiet
sudo pip2 install virtualenv --quiet

If you skip 'sudo apt-get update -qq' your pip will become corrupt and display the 'cannot find main' error.
