Question

我创建了一个简单的django＆react应用程序（目前仅加载了react默认页面），我正尝试部署到Heroku。当我在本地主机上运行python manage.py runserver时，它运行良好（显示默认的反应页面），但是当我将其部署到Heroku时，出现以下错误：

TemplateDoesNotExist at / index.html

这是站点：https://temp-app-test.herokuapp.com/

我敢肯定，我在index.html中使用os.path.join(BASE_DIR, 'build')将settings.py包含在模板中，但这是行不通的。我还在"postinstall": "npm run build"文件的scripts中包括了package.json。
