django - 将 Django+React 部署到 Heroku - Uncaught SyntaxError: Unexpected token '<'
问题描述
我正在尝试将我的 Django + React 应用程序部署到 Heroku。(Django 仅用于 api,React 用于前端。)我关注了这个视频,但好几天都无法解决这个问题。
部署过程中没有错误,但是部署后,只显示白色的空白屏幕。 这是我到现在为止唯一能找到的线索……
我尝试添加type="text/babel"
到您的脚本标签,将base href
标签添加到 index.html,并更改了几个package.json
和settings.py
选项。
这是我的package.json
文件。

我没有接触任何关于 webpack 和 babel 的东西,因为我使用 create-react-app 来创建应用程序。
对于数据库,我使用 MySQL。我解压了 Django 和 React 文件夹,所以每个文件夹都在同一个目录中,就像这样。
我几乎阅读了谷歌中与这个问题相关的每一篇文章,现在我不知道我应该尝试什么。
任何帮助将非常感谢!
解决方案
我尝试了完全不同的方法并成功了!这是我提到的链接。 https://dev.to/shakib609/deploy-your-django-react-js-app-to-heroku-2bck
