webpack管理輸出

主要是使用clean-webpack-plugin引發的錯誤

1.這麼寫就會就會引起第一個問題，是因爲引入版本比較高致使的npm install clean-webpack-plugin --save-dev

+ const CleanWebpackPlugin = require('clean-webpack-plugin'); plugins: [ + new CleanWebpackPlugin(['dist']), new HtmlWebpackPlugin({ title: 'Output Management' }) ]

 

 這個錯誤告訴咱們導入的類型不對，須要修改，給導入行加大括號解決

+ const {CleanWebpackPlugin} = require('clean-webpack-plugin'); plugins: [ + new CleanWebpackPlugin(['dist']), new HtmlWebpackPlugin({ title: 'Output Management' }) ]

2.而後運行還會引起第二個錯誤，這個錯誤告訴咱們使用這個類參數得是一個對象

 

 其實不填也能夠，填一個空的{}也行，清除的目錄會默認以輸出口目錄爲準

const {CleanWebpackPlugin} = require('clean-webpack-plugin');    plugins: [        new CleanWebpackPlugin(),        new HtmlWebpackPlugin({            title: 'Output Management'        })    ],
