Django TypeError：“PosixPath”类型的参数不可迭代

Question

我使用的是最新版本的django django 2.2.12

我尝试在使用命令迁移之前检查错误

python3 manage.py check

但随后它抛出了下面的错误

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    main()
  File "manage.py", line 18, in main

确保您在项目级 settings.py 中导入了 os ：

 import os

在 settings.py 的 DATABASES 中添加以下内容：

 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),

在最新版本的 django 中，我们可以使用 str() 进行以下设置：

 DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': str(BASE_DIR / "db.sqlite3"),
    }
}
