文件从 python.exe 运行

Question

I just switch laptops and everything seems to be normal except this. When I open CMD and try to run a file like py filename.py

it comes up with an error

C:\\Users\\john\\AppData\\Local\\Programs\\Python\\Python37\\python.exe: can't open file 'filename.py': [Errno 2] No such file or directory

It defaults to the python.exe file. It does it for every file that I try to run as well. I am in the correct directory (the directory where the actual file is in) but it keeps defaulting to that error. I am running windows 10 with python 3.7.3.

You may have to change the default directory where your terminal looks for the python.exe file and its packages. You must change both. One variable points to the python[version] folder and the other points to the python[version]\\scripts folder.

This page shows you how to redirect your terminal in windows:

Another tip is that you must change these two identical directories for both the "user variables" and the "system variables" listed in the section below it. I believe the Python installation has probs with this, especially if it's a reinstall or a failed update. And on Windows in general.

Best,
