带有 create-react-app 的 WebStorm 在 /public/index.html 中有文件，到 /public 的文件夹路径标记为 %PUBLIC_URL% .
找不到目录%PUBLIC_URL%因为它不存在，也不应该存在。
除了用 <!--suppress HtmlUnknownTarget --> 抑制错误之外, 有没有办法在 Webstorm 中为目录变量设置别名，如 %PUBLIC_URL% , 到 /public 的根路径在开发中没有编辑器错误？

manifest.json provides metadata used when your web app is added to the
homescreen on Android. See https://developers.google.com/web/fundamentals/engage-and-retain/web-app-manifest/
-->
<link rel="manifest" href="%PUBLIC_URL%/manifest.json">
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
<!--
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`.

This is a good time to address that funky looking %PULIC_URL% tag. Remember the ‘escape hatch’ React provides in case we put assets in the public folder? During the build, assets prefixed with the %PULIC_URL% tag will be recognized and complied. However this is NOT best practice and should be used only when necessary.
因此，在大多数情况下，您可以将 %PUBLIC_URL% 替换为 public 之类的内容，当然，这取决于您如何构建 React 项目。
