Pip on MINGW64?

Question

I was trying to install Jupyter via MSYS2 shell on a Windows 10 machine (as per https://jupyter.org/install, "Installing Jupyter with pip") - and the process crashed; then I found this:

jupyter notebook fails to start · Issue #1540 · msys2/MSYS2-packages · GitHub

You need to start jupyter notebook from the mingw64 shell, not from the msys2 shell. For me a simple jupyter notebook works as expected.

Ok, so I wanted to try the MINGW64 shell.

Note, in the MSYS2 shell:

user@DESKTOP-PC MSYS /c/
$ python3 -m pip install --upgrade pip

  Found existing installation: pip 19.1
    Uninstalling pip-19.1:
      Successfully uninstalled pip-19.1
Successfully installed pip-19.1.1

So, pip works fine in MSYS2 shell. But if I try MINGW64:

user@DESKTOP-PC MINGW64 ~
$ python3 -m pip install jupyter
C:/msys64/mingw64/bin/python3.exe: No module named pip

user@DESKTOP-PC MINGW64 ~
$ python2 -m pip install --upgrade pip
C:/msys64/mingw64/bin/python2.exe: No module named pip

Note the paths of python above in MINGW64 shells; if we try to see what is the path of Python in MSYS2, it is different:

user@DESKTOP-PC MSYS /c/
$ which python3
/usr/bin/python3

user@DESKTOP-PC MSYS /c/
$ cygpath -w `which python3`
C:\msys64\usr\bin\python3.exe

Anyways - can I use pip for python in MINGW64 shell on Windows 10, and if so - how?

---

EDIT: Just tried installing pip with python3 in MINGW64 - does not work:

user@PC MINGW64 /c/Users/user/Desktop
$ python3 get-pip.py

With Mingw-64, pip is patched downstream in the package. To install the package run: pacman -S mingw-w64-x86_64-python-pip

You should then be able to install jupyter and other packages using python -m pip, but avoid running python -m pip --upgrade pip because that will overwrite the packaged version.

I would also recommend using a virtualenv by running python -m venv .venv and source .venv/bin/activate to keep the pip installed packages completely separate.
