conclusion

To install extensions with PIP, go to the PIP installation directory first. It’s usually in python scripts.

If PIP is not an internal or external command, or a runnable program or batch file, check for PIP packages in the Scripts folder, and then see if the Scripts folder has been added to the environment variable.

【 extension 】 :

Whenever this occurs in CMD:

It’s not an internal or external command, it’s not an error in a runnable program or a batch file, it’s not an executable found, so:

1. There is no executable program \to→ download or install this program, and make sure that PATH contains the corresponding PATH. 2. There is this program, but the PATH does not contain the corresponding PATH \to→ add the corresponding PATH to the PATH.
