Syntax error in existing Django project

Question

I've installed existing Django project very 1st time and I've the problem with starting servers python manage.py runserver

Here it's what I've done

1.Clone the repo,

2.Make a virtual environment

3.Pip install requirements.txt

4.Generate access token and secret key and put in secrets.sh. I've the same SECRET_KEY in settings.py and secrets.sh and I've added secrets.sh to .gitignore

5.Change settings.py as follows:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        'USER': 'name',
        'PASSWORD': '',
        'HOST': 'localhost',
        'PORT': '',
    }
}

And I cannot run python manage.py migrate results below:

(tag_gen) local_user@local_user:~/Repo/tag_gen/generator$ python manage.py runserver

SyntaxError: invalid syntax

Ideas?

When using sqlite3 you can scrap all fields in `DATABASES['default']` but `ENGINE` and `NAME`. — cezar, Nov 09 '17 at 10:49

The project you're trying to run is using Python ≥ 3.5, but you're trying to run it in 2.7.

The syntax (request: WSGIRequest): is a type hint. It was introduced a few years ago, but was only added to the newer versions of Python 3. No effort was made to support Python ≤ 3.4.

You'll need to look up instructions on how to create a virtualenv with a high enough version of Python. This changes based on operating system, so verbose instructions are probably out of scope for this question, but there is plenty of advice on the topic already.

Yup, you're right. I've prepared new venv and works. Thanks. — Damian Silkowski, Nov 09 '17 at 12:04

1.Check python and django versions you have should be compatible with the installed requirements. if you have python version more than 3.+ run server with

python3 manage.py runserver

else if python version 2.7+

python manage.py runserver
