[Solved]-Django 3.1+: (fields.E180) SQLite does not support JSONFields

For using JSONField with Django 3.1+ and sqlite, the JSON1 sqlite extension must be installed.

To enable JSON1 on sqlite follow the instructions on Django’s wiki: https://code.djangoproject.com/wiki/JSON1Extension.

Instructions for Windows:

Edit: As of Python 3.9, the official Python installer on Windows already includes the JSON1 extension by default. Upgrade your python version to solve this issue.

For Python 3.8 and below:

• Check your python installation – is it 32bit or 64bit? run: python -c "import platform;print(platform.architecture()[0])"
• Download the precompiled DLL that matches your Python installation (32-bit or 64-bit).
• Locate your Python installation. By default, it should be in %localappdata%\Programs\Python\PythonXX, where XX is the Python version. For example, it’s located in C:\Users\<username>\AppData\Local\Programs\Python\Python37. If you added Python installation directory to your PATH environment variable, you can run the command where python on a command prompt to locate it.
  Enter the DLLs directory in your Python installation.
• Rename (or delete) sqlite3.dll inside the DLLs directory.
• Extract sqlite3.dll from the downloaded DLL archive and put it in the DLLs directory.
• Now, the JSON1 extension should be ready to be used in Python and Django.

I had same problem while trying to apply migrations of django-allauth module; and switching to new version of Python solved it.

According to Django site, version should be 3.9+.
