Python 从GitHub克隆应用程序后如何修复不一致的迁移历史

我正在用《Django初学者手册》来学习Django。 我从GitHub克隆了一个存储库，其中包含一个网站的代码，该网站只允许用户创建帐户、登录和注销

这是存储库：

我的目标是使用这个网站，能够创建一个帐户，登录和注销它

我输入文件夹并在终端中运行以下命令：

pipenv shell
pipenv install
python manage.py runserver

Watching for file changes with StatReloader
Performing system checks...

System check identified no issues (0 silenced).
October 05, 2020 - 12:58:48
Django version 3.1, using settings 'config.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

这是终端中的输出：

pipenv shell
pipenv install
python manage.py runserver

Watching for file changes with StatReloader

System check identified no issues (0 silenced).

Django version 3.1, using settings 'config.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

当我尝试在网站中创建帐户时，它出现以下错误：

OperationalError at /accounts/signup/

no such table: accounts_customuser

要解决此问题，我尝试运行以下命令：

python manage.py makemigrations
python manage.py migrate

它是成功的，并给出了以下输出：

No changes detected
Operations to perform:
  Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
  No migrations to apply.

但是，当我尝试创建帐户时，仍然会出现相同的错误：

OperationalError at /accounts/signup/

no such table: accounts_customuser

accounts应用程序中没有migrations文件夹，因此我只迁移了accounts应用程序：

python manage.py makemigrations accounts
Migrations for 'accounts':
  accounts/migrations/0001_initial.py
    - Create model CustomUser

├── admin.py
├── apps.py
├── forms.py
├── __init__.py
├── migrations
│   ├── 0001_initial.py
│   └── __init__.py
├── models.py
├── tests.py
├── urls.py
└── views.py

python manage.py迁移帐户

引发错误：

python manage.py migrate accounts
django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before 
its dependency accounts.0001_initial on database 'default'.

我不明白为什么会出现这些错误，以及我应该如何修复它们

这是我的帐户应用程序的结构：

python manage.py makemigrations accounts
Migrations for 'accounts':
  accounts/migrations/0001_initial.py
    - Create model CustomUser

├── admin.py
├── apps.py
├── forms.py
├── __init__.py
├── migrations
│   ├── 0001_initial.py
│   └── __init__.py
├── models.py
├── tests.py
├── urls.py
└── views.py

这是

0001_initial.py

中的代码：
