django - django+react 应用部署到 Heroku 时 TemplateDoesNotExist at / index.html 出错

Question

我创建了一个简单的 django & react 应用程序（现在只加载 react 默认页面），我正在尝试部署到 Heroku。当我python manage.py runserver在 localhost 上运行时，它运行良好（显示默认反应页面），但是当我将它部署到 Heroku 时，出现以下错误：

TemplateDoesNotExist at / index.html

这是网站：https ://temp-app-test.herokuapp.com/

我很确定我使用in包含index.html在模板中，但它不起作用。我也包含在文件中。os.path.join(BASE_DIR, 'build')settings.py"postinstall": "npm run build"scriptspackage.json
