manage.py runserver 无输出

Question

I've updated python 3.7 to 3.8 and after that when I want to run py manage.py runserver , or any other commands which are related to manage.py, I've got no output.

I read about environment variables and here is mine, which seems fine to me.

Answer 1

The problem was with the virtual environment. I think because I changed my python version, now I have to create a virtual environment first otherwise py manage.py runserver will not work. But, in previous version (3.7) I was able to do it without a virtual environment.

Answer 2

uninstall python and reinstall it (globally), means before installing select add path to system variable then select custom installation and select install for all users and install. now the python command will work, no need to use only py now. and remember if you run visual code, only install system installer not user installer. after open vscode terminal and type:

python -m django --version

to see django version. then type

pip uninstall django

and enter. it will uninstall django. now exit and goto

C:\Users\(username)\AppData\Roaming\

path from file explorer and delete python folder, then goto

C:\Users\(username)\AppData\Local\

path from file explorer and delete pip folder. now run vs code as administrator and in terminal type

pip install django

it will reinstall django(make sure it's not installing in

C:\Users\(username)\AppData\Roaming\

now you can run the server globally without any problem.

Answer 3

py -3.9 manage.py runserver

Trust me, I literally wasted around 4hrs because of that path issue and this one.
I uninstalled everything and learned the whole process :P
