webpack-dev-server打开localhost：8080 / undefined

Question

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

webpack-config.js devServer部分：

devServer：{

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

    compress: true,

    stats: "errors-only",

    hot: true,

    open: true

如果删除URL的/ undefined部分，即使更换热模块也能正常工作，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.

这似乎是由一个错误引起的：https://github.com/webpack/webpack-dev-server/issues/960

提供快速解决方法（here）：

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