Heroku找不到反应index.html（TemplateDoesNotExist）

Question

我不确定自己在做什么错。我遵循了本教程https://alphacoder.xyz/deploy-react-django-app-on-heroku/，并克隆了git repo。 该教程介绍了如何创建django，响应应用程序并将其推送到heroku

• 我将“ build” =>替换为模板，并将文件夹build重命名为模板'DIRS': [os.path.join(BASE_DIR, 'build') ],。但是因为它不起作用，我将其改回了构建
• 我在每个子文件夹中创建了一个包含index.html的构建文件夹。

在代码下面，您找到我的文件夹结构和heroku错误消息。 这是git repo的链接： https://github.com/gwillig/testreact_heroku

任何建议都值得赞赏
