我正在尝试遵循以下工具包的入门教程django oauth：

https://django-oauth-toolkit.readthedocs.io/en/latest/rest-framework/getting_started.html

当我运行时migrate，我收到此错误：

如果 type_ 不是 None 并且 infodict ['type'] != type_: KeyError: 'type'

任何帮助，将不胜感激。

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