由 firebase 部署和托管 React App 时获取空白页面

Question

当我通过 firebase 部署我的网站域后，我得到一个空白页面 - 我知道我做错了什么，我说（是）覆盖我的 index/html 文件的选项运行 firebase 初始化。

我尝试通过各种方法解决它，我已经用我的原始文件替换了 firebase 生成的构建文件夹中的 index.html 文件，并添加了所需的基础和脚本标签，所以现在至少是空白页面加载和 React App 名称和登录选项卡显示它正在加载。但是内容没有显示。

我已经尝试将 firebase.json 更改为 ["hosting": {"public": "dist",] 原来的 ["hosting": {"public": "build",] 但是这没有用，因为我在 cmd 上收到此错误：错误：指定的 public 目录 'dist' 不存在，无法将托管部署到站点...

相关代码如下，如果您需要更多代码片段，请评论。

      manifest.json provides metadata used when your web app is installed on a
      user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/
    -->
  <link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
  <!--
      Notice the use of %PUBLIC_URL% in the tags above.
      It will be replaced with the URL of the `public` folder during the build.
      Only files inside the `public` folder can be referenced from the HTML.

      Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
      work correctly both with client-side routing and a non-root public URL.
      Learn how to configure a non-root public URL by running `npm run build`.

Answer 1

试试 "public": "./"

Answer 2

您应该 select 'N' 将 URL 重写为 index.html。

所以，我建议您重新进行 firebase 初始化。
