SyntaxError: Generator expression must be parenthesized
TL; DR: Upgrade Django to version 1.11.17+ or 2.0+
This error is a known incompatibility related to Python issue #32012. Projects based on Django 1.11.16 and below will raise this exception when started with Python 3.7. A patch for this issue has been merged into Django 2.0 and 2.1 branches and cherry-picked later into Django 1.11.17.
Note: Python 3.7 is officially supported by Django 1.11.17 and above, including any 2.x branch.
Had same issue. This is how I changed to django version 2.0 and used python3
- $pip3 install django==2.0
- $python3 manage.py runserver
- Install this version:
pip install django==1.11.17 - Run cmd.
- go to your project folder.
python manage.py runserver- it will give a URL for server and you are good to go.
