django - 在heroku中部署django应用程序后TemplateDoesNotFound错误

Question

我已经在 Heroku 上成功部署了我的 Django 应用程序。但它根本没有运行。这里显示的问题是 TemplateDoesNotExist 错误，它告诉它找不到我在每个其他模板中扩展的base.html文件。但是我已经在本地环境中启动并运行了所有模板。

这是错误日志-

TemplateDoesNotExist at /

模板加载器事后显示以下问题 -

Template-loader postmortem
Django tried loading these templates, in this order:

Using engine django:

django.template.loaders.filesystem.Loader: /app/templates/base.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/.heroku/python/lib/python3.6/site-packages/django/contrib/admin/templates/base.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/.heroku/python/lib/python3.6/site-packages/django/contrib/auth/templates/base.html (Source does not exist)

settings.py文件如下所示-

我尝试了这个答案的解决方案，但在我的情况下它不起作用。

我检查了本地环境的所有内容，一切似乎都很好。

我的开发环境是windows。
