Django 3.1+: (fields.E180) SQLite does not support JSONFields

Question

I have created a Django project with the new JSONField announced in Django 3.1, which supports all databases.

I have successfully used this field on a linux machine, but running python manage.py migrate with the same project on Windows fails with the following message:

(fields.E180) SQLite does not support JSONFields.

The same versions of Python and Django are used in both PCs.

Answer 1

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:

• 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).
• 找到您的 Python 安装。默认情况下，它应该在 中%localappdata%\Programs\Python\PythonXX，其中 XX 是 Python 版本。例如，它位于C:\Users\<username>\AppData\Local\Programs\Python\Python37. 如果您将 Python 安装目录添加到 PATH 环境变量中，则可以where python在命令提示符下运行该命令来定位它。在 Python 安装中输入 DLLs 目录。
• sqlite3.dll在DLLs目录内重命名（或删除）。
• sqlite3.dll从下载的 DLL 存档中提取并将其放入DLLs目录中。
• 现在，JSON1 扩展应该可以在 Python 和 Django 中使用了。
