webpack使用compression-webpack-plugin插件的时候报错Cannot read property 'emit' of undefined

相关代码

const CompressionPlugin = require('compression-webpack-plugin')

webpackConfig.plugins.push(

new CompressionPlugin({
  // asset: '[path].gz[query]',
  algorithm: 'gzip',
  test: new RegExp(
    '\\.(js)$' 
    // '\\.(' +
    // configItem.productionGzipExtensions.join('|') +
    // ')$'
  ),
  threshold: 10240,
  minRatio: 0.8
})

错误如下

compiler.hooks.emit.tapAsync({ name: 'CompressionPlugin' }, emit);

TypeError: Cannot read property 'emit' of undefined

at CompressionPlugin.apply (C:\MyWayProject\2018\vue\ehrAdmin\node_modules\compression-webpack-plugin\dist\index.js:175:20)
 

 

把compression-webpack-plugin降到1.1.12就不会报错了
