我正在尝试从webpack 1转换为2但webpack似乎没有使用devtool生成源映射文件:'source-map'.如果我使用以下配置运行webpack,bundle.js文件/public将按预期创建,但没有bundle.js.map文件,也没有错误.使用webpack 1,它按预期工作:

const webpack = require('webpack')

module.exports = {
  entry: ['babel-polyfill', './src/index.js'],
  output: {
    path: './public',
    filename: 'bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'babel-loader'
      }
    ]
  },
  devtool: 'source-map',
  plugins: [
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
        API_BASE_URL: `"${process.env.API_BASE_URL || '/api/v1'}"`
      }
    }),
    new webpack.optimize.UglifyJsPlugin()
  ]
}

CLI输出:
