我正在尝试遵循来自以下位置的 django oauth
工具包入门教程:
https://django-oauth-toolkit.readthedocs.io/en/latest/rest-framework/getting_started.html
当我运行migrate
时,出现以下错误:
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/db/backends/base/schema.py", line 1003, in _constraint_names if type_ is not None and infodict['type'] != type_: KeyError: 'type'
如有任何帮助,我们将不胜感激。

最佳答案
这个错误似乎是由 oauth2_provider 迁移引起的。您应该能够通过进入 {your venv}/Lib/site-packages/oauth2_provider/migrations 并删除所有迁移文件(init.py 除外)然后再次运行 migrate 来修复它。希望这会有所帮助
