AttributeError：'tuple'对象没有'rsplit'属性 Django

Question

我刚接触Django，运行命令python manage.py collectstatic后出现了这个错误。

Traceback (most recent call last):
  File "manage.py", line 10, in <module>

AttributeError: 'tuple' object has no attribute 'rsplit'

当我运行runserver时，输出是这样的：

Answer 1

我在使用djoser进行Django Rest Framework的身份验证时遇到了这个错误。只需要把

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_simplejwt.authentication.JWTAuthentication',
        (...)
    ),
}

改成

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_simplejwt.authentication.JWTAuthentication',
     
    ),
}

Answer 2

我也遇到过同样的问题。

我从django restframework的文档中复制了以下设置：

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_simplejwt.authentication.JWTAuthentication',
        (...)
    ),
} 

到我的项目里。然后我把上面提到的设置中的(...)去掉了，现在可以正常工作了。请在复制代码时小心一点 ))

其实正确的做法是：

    REST_FRAMEWORK = {
        'DEFAULT_AUTHENTICATION_CLASSES': (
'rest_framework_simplejwt.authentication.JWTAuthentication',
        ),
    }

在这个情况下，(...)的意思是“把你已有的代码”放在它前面。

Answer 3

你在 settings.py 文件中的某个设置是一个元组，或者有一个多余的逗号，这样就把它变成了元组，但其实它不应该是元组。它应该是一个字符串。

我建议你先检查一下 STATICFILES_STORAGE 和 DEFAULT_FILE_STORAGE 这两个设置。
