trying to export as exe and getting an error with pyinstaller

Question

so I'm trying to export this .py as an exe using pyinstaller. I have found it in path with cmd :

C:\Users\me>path
PATH=C:\Users\me\AppData\Local\Programs\Python\Python39\Scripts\pyinstaller.exe

however, when I use this command:

C:\Users\me\PycharmProjects\Rickroll>pyinstaller --onefile main.py

I get the message

'pyinstaller' is not recognized as an internal or external command,
operable program or batch file.

please can you help me understand why?

Answer 1

So i've fixed the problem. I essentially had to totally reset my computer. it did the trick. So essentially, the whole thing was messed up because of something my brother did on it a while back. the pip files were there but unresponsive. it was due for a reset anyway.,
