Django runserver 命令失败

Question

I've been learning Python for a few months and a couple days ago i decided to learn one of Web frameworks. I found some tutorials on Django and it was looking really cool until i tried to use "runserver" command. As you can see i used the basic line "python -m django runserver manage.py" and got a lot of calls. I've just installed Django and i wasn't changing anything in it's scripts. I only started by creating a new project that worked perfectly with "python -m django startproject djangoLearn". Do you have any thoughts on how can i fix this problem? This problem prevents me from further learning beacuse i can't see my own project:(( Thanks in advance. Hope y'all have a great day. Calls that i get while trying to run server:

Answer 1

I hope your virtualenv is activated?? use this to create project django-admin startproject projectname. take note of the period it works without the period though.

use python manage.py startapp appname to create an app don't forget to register the app in INSTALLED_APP

i think the code you want to use is python manage.py runserver

but if you use python3 use python3 manage.py runserver just use whatever you use to start your python before manage.py runserver

Answer 2

you should first activate your virtual environment. with a command like this in linux:

source "path-to-activate-file"

and command like this in windows:

\pathto\env\Scripts\activate
