Python manage.py runserver throws an error

Question

I have been running my python server for a few months now and I have had no problems, but ever since I have installed react-native I now get the following error. I don't know if the python problem is related to the installation of react-native but it seems like a bit of coincidence.

Any help in solving this issue would be appreciated

File "manage.py", line 14
) from exc
     ^
 SyntaxError: invalid syntax code here

My manage.py file:

#!/usr/bin/env python
import os
import sys


if __name__ == '__main__':
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'my_website.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)

Answer 1

I fixed this my installing python 3.7 and running

py -3 manage.py runserver

I also had to reinstall the packages that were being used on my project

Answer 2

You are trying to use a Python-3-specific Django version with a Python 2 interpreter. You will clearly see that if you look at the top of the full stacktrace

raise ... from ... is a Python 3 syntax. A Python 2 interpreter will treat it as a SyntaxError as can be demonstrated here .

Make sure you are using Python 3 to execute this server.
