代码片段
const HtmlWebpackPlugin = require('html-webpack-plugin')

new HtmlWebpackPlugin({
  filename: 'index.html',
  template: 'index.html',
  favicon: resolve('favicon.ico'),
  inject: true,
  templateParameters: {
    conf: require('../conf.json')
  }
}),

"html-webpack-plugin": "^3.0",

当前解决办法 版本问题，改成下面的版本就正常了。

"html-webpack-plugin": "^2.30.1",
