我迷失了一个可能是一个非常简单的问题，配置一个django / mysql项目。我在计算机A上有一个正在工作的项目，我只是想能够与计算机B一起使用。在计算机A上，我有一个Eclipse项目，使用Pydev和Django，一个本地虚拟环境，以及一个运行Mysql的本地数据库。
我所做的：

• 我导出了虚拟环境（包括django）并在计算机B上创建了相同的环境;
• 我使用Gitlab来获取所有包含代码的文件;
• 我安装了Mysql，并创建了一个同名的数据库，以及一个具有相同信息的用户（id / pwd）。

迁移进行得很顺利，表的创建符合我的预期。但是，我找不到运行服务器的方法。当我尝试时，我得到多个错误，说一个（也只有一个）应用程序尚未加载，然后是另一个错误，这似乎与数据库有关。以下是一些信息：

edit：User模型代码如下：

from django.db import models
from django.contrib.auth.models import AbstractUser

class Group(models.Model):
    name = models.CharField(max_length=100)
    def __str__(self):
        return self.name   
    
class User(AbstractUser):
    groups = models.ManyToManyField(Group)
    current_group = models.ForeignKey(Group, on_delete=models.SET_NULL,blank = True , null = True, related_name="current_group")

编辑2：实际上，似乎大多数错误都与User django类的导入有关，例如与www.example.com相关的错误forms.py在第2行，这是一个：

from django.contrib.auth.forms import UserCreationForm, AuthenticationForm, UsernameField

型
我确切地说，我在我的settings.py中有以下一行，因为我使用个性化的用户模型，但是我试图删除这一行，问题仍然存在：

AUTH_USER_MODEL = 'members.User'

型
我真的不明白这里发生了什么，所以我会很感激，如果有人能帮助，非常感谢！
