Django-admin 命令错误 无法启动项目

Question

I am trying to start a project in a virtual environment using the django-admin command.

pip freeze output: django==2.0.7 (part of the tutorial same happens w/ update package) pytz==2021.3

The error I get for django-admin check is

This just started after I had deleted my old project to start again using a comprehensive tutorial. I have tried deleting the virtualenv via clearing the \dev\django\ folder, and restarting.

I've seen other questions answered by editing the settings.py or manage.py file, but I don't have those at this stage.

Thanks.

Update#1: Tried repairing python installs, and doing the same thing on another user. Still get the error. I have noticed that launching the django-admin.py and.exe only difference is that the.exe goes through runpy.py first

I made a mistake with the errors this is the error for django-admin startproject

Update#2 I updated to Django 3.0.0 Pip freeze output:

asgiref==3.4.1
Django==3.0
pytz==2021.3
sqlparse==0.4.2

It works I can use the django-admin startproject. I'm still weirded out that it worked with 2.0.7, and didn't work before with an updated package.

Answer 1

looks like you on the python shell are you sure you on the cmd if not try cmd

Answer 2

In you settings.py file there should be a variable called TEMPLATES

When starting a fresh project it should look something like this:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR,'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                 'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

From the error message you have shown us, im guessing this may be missing or misconfigured somehow.

Answer 3

Try a different method of creating your project and see if that works?

python -m django <command>

I have also double checked and youre using a really old version of django and i dont recommend.

Perhaps try upgrading to a later version of django and retry the original command aswell?

Answer 4

I have trouble somethink like you.. And i resolve by using this command:

python -m pip install -U Django

this is mean we cant upgrade your our jdango version..

And you cant try aganin to make new project with command:

django-admin startproject yournameproject

goodluck
