django - ValueError:依赖于没有迁移的应用程序
我正在使用Dokku将Django项目部署到VPS。我的项目使用CustomUser模型，项目中有两个应用程序：accounts，它有CustomUser和gradebook。
在部署期间，流程运行、生成和迁移。在部署之后，当我运行python manage.py showmigrations时，会得到以下内容：
account
[X] 0001_initial
[X] 0002_email_max_length
accounts
(no migrations)
admin
[X] 0001_initial
[X] 0002_logentry_remove_auto_add
[X] 0003_logentry_add_action_flag_choices
auth
[X] 0001_initial
[X] 0002_alter_permission_name_max_length
[X] 0003_alter_user_email_max_length
[X] 0004_alter_user_username_opts
[X] 0005_alter_user_last_login_null
[X] 0006_require_contenttypes_0002
[X] 0007_alter_validators_add_error_messages
[X] 0008_alter_user_username_max_length
[X] 0009_alter_user_last_name_max_length
[X] 0010_alter_group_name_max_length
[X] 0011_update_proxy_permissions
[X] 0012_alter_user_first_name_max_length
contenttypes
[X] 0001_initial
[X] 0002_remove_content_type_name
gradebook
(no migrations)
sessions
[X] 0001_initial
sites
[X] 0001_initial
[X] 0002_alter_domain_uniqueaccount来自django-allauth。看来我的应用程序没有被迁移。于是我做了：
me@myserver:/home$ dokku run gradebook python manage.py makemigrations accounts
success
Migrations for 'accounts':
accounts/migrations/0001_initial.py
- Create model CustomUser
me@myserver:/home$看起来东西已经准备好迁移了。然后运行迁移并获得一个错误django - ValueError: Dependency on app with no migrations: accounts。
shmish@Henry:/home$ dokku run gradebook python manage.py migrate accounts
success

2021/08/25 16:19:16 exit status 1此时，我无法迁移我的任何一个应用程序。我发现另一件奇怪的事情是，我仍然能够createsuperuser、进入shell、from accounts.models import CustomUser并成功地查询CustomUser。
此错误看起来类似于以下内容：ValueError: Dependency on app with no migrations: account，但我没有看到解决方案。
Next我在开发服务器和prod服务器上重新创建了我的数据库。在dev上，我重新运行初始迁移，然后提交到我的存储库。然后，我部署到生产服务器上。迁移看起来很有效，但我无法通过登录和注册表单。我一直无法确定确切的错误是什么，但是页面超时了，并给出了一条信息：“我们很抱歉，但是出了问题。”我认为这是一条nginx信息。
经过几次尝试部署来解决这个问题后，我得到了新的迁移错误：
Your models in app(s): 'account' have changes that are not yet reflected in a migration, and so won't be applied.
Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.这是一个无穷无尽的循环，似乎工作，然后迁移，然后错误回来。
注意-我能够进入shell并手动创建一个CustomUser对象，但是我无法通过网站第一页上的表单。
现在看起来就像2015年的错误：Django Heroku Error "Your models have changes that are not yet reflected in a migration"
所有这些在我的开发环境中都很好，最大的区别是它是Docker，而prod是Dokku。

检查git忽略、使文件夹迁移注释或从gitignore文件中删除
