webpack 用 webpack-parallel-uglify-plugin 加速打包报错

Question

用 UglifyJsPlugin 可以正常打包，就是很慢

new webpack.optimize.UglifyJsPlugin({
   compress: {
     warnings: false
   },
   sourceMap: true
}),

用 ParallelUglifyPlugin 加速打包之后

new ParallelUglifyPlugin({
      cacheDir: '.cache/',
      uglifyJS: {
        output: {
          comments: false
        },
        compress: {
          warnings: false
        }
      },
      sourceMap: config.build.productionSourceMap
    }),

打包失败，报错

ERROR in Encountered an error while minifying static/js/0.feb0ac937597219abdc1.js:
`warnings` is not a supported option

webpack 2.6.1 webpack-parallel-uglify-plugin 1.1.0

Answer 1

删除

compress: {
  warnings: false
}

即可

Answer 2

将：
compress: {
warnings: false
}
改为：
warnings: false

Answer 3

这里有个坑，可以查看一下webpack官网 uglifyoptions 的配置

new UglifyJsPlugin({
  uglifyOptions: {
    compress: {
      drop_console: true,
      drop_debugger: false,
      pure_funcs: ['console.log'] // 移除console
    },
    warnings: false
  },
  sourceMap: false,
  parallel: true
})
