如何在 Windows10 Path 中使用两个 Python3.x 版本访问 pip3？

Question

I have added two Python versions to my path.

C:\Program Files\Python38\Scripts\
C:\Program Files\Python38\
C:\Program Files\Python37\Scripts\
C:\Program Files\Python37\

Within each \\Scripts directory are these pip executables:

Program Files/Python38/Scripts
├── easy_install-3.8.exe
├── easy_install.exe
├── f2py.exe
├── pip-script.py
├── pip.exe
├── pip3-script.py
├── pip3.8-script.py
├── pip3.8.exe
└── pip3.exe

.Program Files/Python37/Scripts
├── easy_install-3.7.exe
├── easy_install.exe
├── pip.exe
├── pip3.7.exe
└── pip3.exe

I cannot seem to use pip3 since adding Python3.7 to my Path environment variable.
