您好,我是 python 和 django 的新手,我正在练习 django,但是当我命令 python manage.py makemigration 和 python manage.py migrate 时,我收到了标题中显示的错误。下面提到了完整的错误。
寻求帮助,谢谢

最佳答案

我刚刚在这个问题中回答了同样的错误 How can I resolve the argument of type 'WindowsPath' is not iterable in django? not opening any pdf or csv files

好像设置DATABASES - NAME需要一个字符串,而不是 Path目的。
在您的设置中尝试更改此行

'NAME': BASE_DIR / 'db.sqlite3',
'NAME': str(BASE_DIR / 'db.sqlite3'),
以便 NAME是一个字符串而不是 Path .

错误来自这行代码 django/db/backends/sqlite3/creation.py#L13 似乎 this commit解决了这个问题,所以在 Django v3.1.1没有必要使用 'NAME': str(BASE_DIR / 'db.sqlite3'),不再,只需使用 'NAME': BASE_DIR / 'db.sqlite3',应该够了。

关于python - 返回database_name == ':memory:' or 'mode=memory' in database_name TypeError : argument of type 'WindowsPath' is not iterable,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/64046773/
