添加uglifyjs-webpack-plugin配置时，

运行报错：

UglifyJs Plugin Invalid Options

options should NOT have additional properties

错误原因：

使用插件时，我的webpack配置如下：

let OptimizeCssPlugin = require("optimize-css-assets-webpack-plugin")//压缩css 插件
let UglifyJsPlugin = require("uglifyjs-webpack-plugin")//压缩js 插件
module.exports = {
  optimization: {//优化项
    minimizer: [
      new UglifyJsPlugin({
        cache: true,
        patallel: true,
        sourceMap: true,
        test: /\.js(\?.*)?$/i,
      }),//js优化
      new OptimizeCssPlugin()//css优化插件
    ]
  },
}

报错提示意思是：最小化选项不应具有其他属性

说明我的参数加多了。。。

解决办法：

最后修改配置项，将这两个配置加入plugins配置中：

let OptimizeCssPlugin = require("optimize-css-assets-webpack-plugin")//压缩css 插件
let UglifyJsPlugin = require("uglifyjs-webpack-plugin")//压缩js 插件
module.exports = {
  plugins: [//存放所有插件
    new OptimizeCssPlugin(),//css优化插件
    new UglifyJsPlugin(),//js优化插件
  ],
}

问题得以解决。
