compiler.plugin is not a function

TypeError: compiler.plugin is not a function

[Camille Zhao]

when I use it ,my project throw "TypeError: compiler.plugin is not a function"; Why?

const ParallelUglifyPlugin = require("webpack-parallel-uglify-plugin"); plugins: [ new ParallelUglifyPlugin({ uglifyJS: { output: { beautify: false, comments: false, }, compress: { warnings: false, drop_console: true, collapse_vars: true, reduce_vars: true, }, }, }), ],

const ParallelUglifyPlugin = require('webpack-parallel-uglify-plugin')

Plugins:

 // 使用 ParallelUglifyPlugin 并行压缩输出的 JS 代码
    new ParallelUglifyPlugin({
      // 传递给 UglifyJS 的参数
      // (还是使用 UglifyJS 压缩，只不过帮助开启了多进程)
      uglifyJS: {
        output: {
          beautify: false, // 最紧凑的输出
          comments: false, // 删除所有的注释
        },
        compress: {
          // 删除所有的 console 语句，可以兼容 ie 浏览器
          drop_console: true,
          // 内嵌定义了但是只用到一次的变量
          collapse_vars: true,
          // 提取出出现多次但是没有定义成变量去引用的静态值
          reduce_vars: true
        }
      }
    })

There are some errors:

Webpack5 removes compiler.plugin. So I used webpack@4.44.2, that is ok.

The 2.0.0 release has been updated to work with webpack 5, webpack 3 will not work with 2.0.0
