webpack-dev-server 打开 localhost :8080/undefined

Question

当我运行 $ npm run dev ( "dev": "webpack-dev-server" ) 它打开 localhost:8080/undefined 而不是 localhost:8080 或至少 localhost:8080/index.html

webpack-config.js devServer 部分:

开发服务器:{

    contentBase: path.join(__dirname, 'dist'),

    compress: true,

    stats: "errors-only",

    hot: true,

    open: true

如果我删除 URL 的/undefined 部分，即使是热模块更换，它也能正常工作，所以这不是一个大问题；只是想知道为什么会这样。

编辑:我在 MacOS 上

Edit2: npm run dev 时的控制台信息:
Project is running at http://localhost:8080/
webpack output is served from /
Content not from webpack is served from /Users/cozarkd/folders/dist
webpack: wait until bundle finished: /undefined
webpack: Compiled successfully.

这似乎是由错误引起的:https://github.com/webpack/webpack-dev-server/issues/960

提供了一种快速解决方法 (here):

devServer: {
  contentBase: path.join(__dirname, 'dist'),
  compress: true,
  stats: "errors-only",
  hot: true,
  open: true,
  openPage: '' // <-- this
}
