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

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 -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 -o get-pip.py python get-pip.py --force-reinstall

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

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

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

This command also works. It reinstalls pip:

sudo easy_install pip

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.

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.

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.

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

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

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