Python2 and Python3 compatibility settings under Windows

After installing Python2 and Python3 separately, I want to differentiate directly by command Python2, PIP2 and Python3, PIP3:

Enter the Python installation directory separately, modify Python.exe to Python2.exe, Python3.exe

This allows the direct input of python2 and python3 to be used.

However, when the name is modified, entering PIP2 or PIP3 throws an exception:

inch process using '"'

Online read a lot of programs are said to run directly:

python2-m pipInstall---m pip install---m pipinstall---m PIP install-u Pip

It's good to upgrade the PIP version.

However, if the PIP is the latest version it does not work, this time the need to force the update:

Python2  -m pip install--upgrade--force-Reinstall  Pippython3-m pip install--upgrade-- Force-reinstall pip
