Pip is not working: ImportError: No module named 'pip._internal'

  • 772

Running pip or pip3 results with:

Traceback (most recent call last):
File "/home/myuser/.local/bin/pip", line 7, in <module>
from pip._internal import main
ImportError: No module named 'pip._internal'

I had issues with this, and uninstalled pip3, but when i try to install it again using 

sudo apt-get -y install python3-pip

it does install, but then running pip or pip3 i get the same error.

#which pip3
/home/myuser/.local/bin/pip3
python pip

  1. After upgrading pip (or pip3, in this case) if the following occurs:

    $ ~ pip3 -V
Traceback (most recent call last):
  File "/usr/local/bin/pip", line 7, in <module>
    from pip._internal import main
ModuleNotFoundError: No module named 'pip._internal'

    Force a reinstall of pip:

    curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py --force-reinstall

    Verify install:

    $ ~ pip3 -V
pip 10.0.1 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)

    Now pip3 install <package> and pip3 install --user <package> (for user-level installs) will work correctly.

    There should never, ever be any reason you need to run pip in elevated mode.

    For Python 2.7

    curl https://bootstrap.pypa.io/pip/2.7/get-pip.py -o get-pip.py
python get-pip.py --force-reinstall

    Had same problem on macOS as well, it's a common issue across platforms.

  2. I solved this by updating pip via Python, like this:

    python2 -m pip install --user --upgrade pip
python3 -m pip install --user --upgrade pip

  3. This command also works. It reinstalls pip:

    sudo easy_install pip

  4. Apply these three steps:

    1. Go to /usr/local/bin by terminal
    2. Execute sudo gedit pip
    3. Change the from pip._internal import main into from pip import main.

  5. Check if pip is already installed using

    pip3 -V

    or

    pip3 --version

    If not use this command to install it:

    sudo apt install python3-pip

    Now you can use 

    python3 -m pip install packageName

    to install packages using pip.

  6. I got the same problem as you just now, I found the reason is that you are working without superuser privilege since some internal python packages or modules are installed under superuser privilege.

    So you can try by fist entering sudo su, then enter your password, and run pip install, it might help.

  7. A force re-install of pip with -H flag worked for me:

    sudo -H python3.7 get-pip.py --force-reinstall

  8. The pip version now is 19.0.1:

    which pip3
#/home/xxx/.local/bin/pip3
vim /home/xxx/.local/bin/pip3

    Change from pip._internal import main into from pip import main
