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

    I have a similar problem after upgrading from pip 9.0.2 to pip-10.0.0. Ubuntu 16.04LTS here. – Dave Apr 15 '18 at 11:19

    You should not upgrade to pip 10 on Ubuntu, because the system version installed through apt is modified in a way not compatible to pip 10. See github.com/pypa/pip/issues/5221 @Dave – Byte Commander Apr 15 '18 at 12:27

    Temporary workaround: python3 -m pip install --user <package> – Benjamin R Apr 21 '18 at 22:14

    if you have easy_install (comes from python-setuptools package), you can do sudo easy_install pip (or sudo easy_install3 pip for python3-only, etc.) – Marek Sebera May 25 '18 at 14:40

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.

(note: For Python 2.7, just replace python for python3, and pip for pip3)

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

    Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/bin/pip3' – endolith Aug 21 '18 at 10:44

    @endolith Okay, now you want to use sudo rm -rf /usr/bin/pip3 – purge that existing directory first, then install from scratch. It's a permissions problem on that directory, but it's better to reset in these circumstances I believe, you can always easily reinstall whatever packages you lose again. If that doesn't work, nuke your Python 3 install, too, then reboot. – Benjamin R Aug 23 '18 at 8:57

    @endolith Hi, it depends on what your OS (and distro, if Linux) is. Let me know and I’ll try to point you in the right direction. p.s. We’ve all been in your position more times than most of us like to admit :) – Benjamin R Aug 24 '18 at 14:35

This command also works, it reinstalls the pip:

sudo easy_install pip

    Worked like a wonder on Ubuntu – user2849789 Sep 9 '18 at 0:53

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

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

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

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.

    You should never, ever need to run pip with elevated permissions. Use --user flag instead, as in: pip3 install --user <package> – Benjamin R Apr 21 '18 at 4:44

    However, when I run without superuser permission, I still got the information like pip3 install --user Traceback (most recent call last): File "/usr/local/bin/pip3", line 7, in <module>\\ from pip._internal import main ImportError: No module named 'pip._internal' Could you please help me to figure out why this always happen? – Yuke Apr 22 '18 at 5:21

    Ok, I found out why, if from pip._internal import main error happen, in my solution, 1) curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py 2) python3 get-pip.py --user --force-reinstall, and then you can run pip without superuser permission, Thank you very much for your advice, it helps a lot ! – Yuke Apr 22 '18 at 5:36
  • My pleasure! Look, I learned the hard way to be careful about using sudo willy-nilly (destroyed my OS multiple times!) – Benjamin R Apr 23 '18 at 7:34

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.
0

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

0

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.

  • this is what OP is already dong. – Nik O'Lai Aug 23 at 11:57
