/auth/users/me/ 处的 ModuleNotFoundError 没有名为“accounts”的模块答案

【问题标题】：ModuleNotFoundError at /auth/users/me/ No module named 'accounts'/auth/users/me/ 处的 ModuleNotFoundError 没有名为“accounts”的模块
【发布时间】：2021-10-28 04:10:31
【问题描述】：

我正在使用 djoser 和 django-rest-framework JWT 进行用户身份验证。根据 doc.for djaoser 。我有/user/ 端点用于创建用户，/user/me/ 用于获取详细信息。第一个端点工作正常，但在第二个 /user/me/ 中，它给了我错误

ModuleNotFoundError at /auth/users/me/

No module named 'accounts'

我不知道问题出在哪里。我正在邮递员上测试它。

这是我的 settings.py：

到目前为止我检查过的内容

互联网上的大多数解决方案都建议在 settings.py INSTALLED_APPS 中添加帐户，但我没有创建任何帐户应用程序，因此没有理由添加它。如果您能提供帮助，我将非常感谢您，因为这浪费了我很多时间。谢谢 ❤️❤️❤️

【解决方案1】：

如果您在SERIALIZERS-note 仔细阅读文档这是线索

密钥“user”用于一般用户，而“current_user”允许您为特殊的 /users/me 端点设置序列化程序。不过，它们都默认使用相同的序列化程序。

所以，如果您查看 settings.py 中的 DJOSER SERIALIZERS

'SERIALIZERS': {
    'user_create': 'base.serializers.UserSerializer',
    'user': 'base.serializers.UserSerializer',
    'current_user': 'account.serializers.UserCreateSerializer', #here is the problem. What is 'account' doing here. You should cmoment this
    'user_delete': 'djoser.serializers.UserDeleteSerializer',
}
