React项目build之后资源文件路径为根目录问题解决

找到node_modules -> react-scripts -> config -> paths.js

修改

function getServedPath(appPackageJson) {
  const publicUrl = getPublicUrl(appPackageJson);
  const servedUrl =
    envPublicUrl || (publicUrl ? url.parse(publicUrl).pathname : '/');//改成'./'
  return ensureSlash(servedUrl, true);
}

为

function getServedPath(appPackageJson) {
  const publicUrl = getPublicUrl(appPackageJson);
  const servedUrl =
    envPublicUrl || (publicUrl ? url.parse(publicUrl).pathname : './');
  return ensureSlash(servedUrl, true);
}

再重新编译打包即可
