Gunicorn 寻找已删除的模块;无法在 GCP 中运行 django 应用程序

问：

我有一个在 GCP 上运行良好的 django 应用程序，我最近删除了一个依赖项：.我不需要这个功能，所以我从模型中删除了这些项目，迁移了数据库并卸载了模块。django-colorfields

现在，当我将项目部署到 GCP 时，我无法通过管理员登录页面。管理页面（）显示得很好，但是当我输入用户名和密码并按回车键时，我收到HTTP 500内部服务器错误。https://myproject.com/admin

我检查了内部服务器日志，有许多 gunicorn 错误，但这个很突出：

ModuleNotFoundError: No module named 'colorfield'

[2023-11-09 22:02:29 -0600] [18] [ERROR] Exception in worker process

最后一点-- --让我印象深刻。我已经删除了整个项目中的所有引用（我已经在我的整个项目中进行了查找+替换，但在任何地方都找不到它！），但是由于某种原因，我的GCP部署文件仍然认为它需要这个模块并且每次都有错误。ModuleNotFoundError: no module named 'colorfield'django-colorfield

我的app.yaml文件非常简单：

# [START django_app]
# [START gaestd_py_django_app_yaml]
runtime: python311

env_variables:
  # This setting is used in settings.py to configure your ALLOWED_HOSTS
  APPENGINE_URL: https://my-project.uw.r.appspot.com/
  GOOGLE_CLOUD_PROJECT: my-project
  GS_BUCKET_NAME: "my-bucket"

handlers:
# This configures Google App Engine to serve the files in the app's static
# directory.
- url: /static
  static_dir: static/

# This handler routes all requests not caught above to your main app. It is
# required when static routes are defined, but can be omitted (along with
# the entire handlers section) when there are no static files defined.
- url: /.*
  script: auto
# [END gaestd_py_django_app_yaml]
# [END django_app]

我已经检查了其他常见问题 - 我有DEBUG=TRUE，以防万一。我仍然无法登录我的管理网站，这似乎是我目前拥有的最好的线索。settings.pyALLOWED_HOSTS = [*]

我已经从中删除了它，我卸载了它，我从我的模型中删除了对它的所有提及，我什至删除了我所有的迁移文件并重置了我的数据库，因为我在那里发现了这个模块的提及。我还能做些什么来摆脱这个错误？INSTALLED_APPSpip
