我试图创建一个自定义的用户模型，所以我扩展了AbstractBaseUser和BaseUserManager来进行模型管理。
当我尝试迁移或运行服务器时，出现的错误是：

ModuleNotFoundError: No module named 'django.contrib.messagesdjango'
我的自定义用户模型是：
class Account(AbstractBaseUser):
email = models.EmailField(verbose_name="email", max_length=100, unique=True)
name = models.CharField(verbose_name="full name", max_length=100)
username = models.CharField(max_length=30, unique=True)
date_joined = models.DateTimeField(verbose_name="date joined", auto_now_add=True)
last_login = models.DateTimeField(verbose_name="last login", auto_now=True)
is_admin = models.BooleanField(default=False)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
is_superuser = models.BooleanField(default=False)
USERNAME_FIELD = "email"
REQUIRED_FIELDS = ["username", "name"]
objects = MyAccountManager()
def __str__(self):
return self.email
def has_perm(self, perm, obj=None):
return self.is_admin
def has_module_perms(self, app_label):
return True
模型管理器是：
class MyAccountManager(BaseUserManager):
def create_user(self, email, username, name, password=None):
if not email:
raise ValueError("Users must have an email address")
if not username:
raise ValueError("Users must have a username")
user = self.model(
email=self.normalize_email(email),
username=self.username,
name=self.name
)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, email, username, name):
if not email:
raise ValueError("Users must have an email address")
if not username:
raise ValueError("Users must have a username")
user = self.create_user(
email=self.normalize_email(email),
username=self.username,
name=self.name,
password=password
)
user.is_admin = True
user.is_staff = True
user.is_superuser = True
user.save(using=self._db)
return user
我认为错误可能是因为Python 3.8和Django 3.1不兼容，我已经在我的venv:中安装了它们
点子列表：
Package Version
------------------- -------
asgiref 3.2.10
Django 3.1.1
djangorestframework 3.11.1
pip 20.2.3
psycopg2 2.8.6
pytz 2020.1
setuptools 50.3.0

您的INSTALLED_APPS看起来怎么样？您可能在django.contrib.messages后面缺少一个逗号，或者您不小心复制粘贴了一些东西。
