尝试使用终端创建新的超级用户时遇到以下错误。
TypeError: create_superuser() missing 3 required positional arguments: 'first_name', 'last_name', and 'location'
我在下面的评论中关注了另一个stackoverflow页面。在该页面中，它坚持使用user.save(using=self._db)创建一个create_superuser函数。
这段代码仍然有错误，
如何使用“ first_name”，“ last_name”和“ location”而不提供任何默认值。
first_name，last_name和location是CharField，其max_length = 30，并且可以具有空白值。
在此自定义用户模型中，通过在User类中将用户名设置为唯一，将其替换为mobile_no。

答案 1 :(得分：0)
您可能会遇到此问题，因为您在必填字段中仅指定了电子邮件和角色，而没有first_name，last_name和位置。在声明用户用户管理器时，没有为这些字段提供默认值，因此必须在必填字段中指定它们。那应该可以解决您的问题。
