我正在尝试在 Heroku 上部署我的简单 Django Web 应用程序，但构建失败并出现以下错误：

       During handling of the above exception, another exception occurred:

 !     Error while running '$ python pytorch_django/manage.py collectstatic --noinput'.

我已经在 Heroku 上成功部署了其他 Django 应用程序，但我不明白这里出了什么问题。是什么KeyError: 'collectstatic'意思或它来自哪里？

在本地，该应用程序运行良好，也python manage.py collectstatic运行良好。有什么问题？它可能与 Python 3.9 有关吗？我在本地有 Python 3.8。

编辑：新创建的 Django 应用程序也会发生这种情况 - 代码没有任何变化。

问题是我自己的错，但不是在 Django 应用程序中，而是在我的 Heroku 配置中。在我的 Heroku 环境变量 ( Settings > Config Vars) 中，我DJANGO_SETTINGS_MODULE错误地将project.prod_settings. 但是，我的 Django 项目被调用pytorch_django，所以我不得不将它设置为pytorch_django.prod_settings.

这就是导致错误的原因ModuleNotFoundError: No module named 'project'。更改DJANGO_SETTINGS_MODULE为正确的路径解决了问题。
