在 Heroku 上托管 React App 的问题

Issue in Hosting React App on Heroku

我正在尝试在 heroku 中托管 React 应用程序...

我已经使用 create-react-app 创建了应用程序..并按照以下方法进行托管...

        git init
        heroku create $APP_NAME --buildpack https://github.com/mars/create-react-app-buildpack.git
        git add .
        git commit -m "Start with create-react-app"
        git push heroku master
        heroku open

但是当我尝试将应用程序推送到 heroku 时 returns 出现以下错误...

我该如何解决这个问题?

我刚刚克隆了您的存储库并尝试了 npm install + npm run build。我发现 npm run build 在本地失败。所以,这是代码错误,而不是 Heroku 部署错误。

失败来自 HTMLParser,所以我查看了 public/index.html 并找到了一个高度自定义的模板。

为了检查 public/index.html 内容是否有问题,我将其替换为默认的 create-react-app HTML 模板代码。然后,npm run build成功完成。

因此,似乎 您的 public/index.html 中 HTML 的有效性存在问题,这会破坏 create-react-app 的模板引擎。我建议 运行 通过 HTML validator 来查找问题,或者手动将模板分解成更小的可测试部分,直到找到导致构建错误的部分。
