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

I fixed this problem by

sudo apt-get install python3-pip

this worked even for python2.7, amazing...

Answer 2

An answer from askUbuntu works.

For pip2.7, you can at first curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py, then python2.7 get-pip.py --force-reinstall to reinstall pip.

Problem solved. Also works for python3.

Answer 3

Its probably due to a version conflict, try to run this, it will remove the older pip somehow.

sudo apt remove python pip

Answer 4

My solution is adding import pip to the script linked to the pip/pip3 commands.

Firstly, open the file (e.g. /usr/local/bin/pip) with your favorite text editor and the sudo mode. For example, I use sudo vim /usr/local/bin/pip to open the script file.

You will obtain some file as following:

import re
import sys

from pip._internal import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

Afterwards, insert the statement import pip just before the from pip._internal import main then the issue is resolved.

Answer 5

I have fixed this error by running the following commands:

sudo apt remove python-pip
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

It will remove the previously installed pip and reinstall it. Thanks :)

Answer 6

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.
