webpack清理插件錯誤——TypeError: CleanWebpackPlugin is not a constructor

Error: clean-webpack-plugin only accepts an options object.

TypeError: CleanWebpackPlugin is not a constructor

以上兩個錯誤屬於同一個

以前這樣寫的：

const CleanWebpackPlugin = require("clean-webpack-plugin");

plugins:[
 new CleanWebpackPlugin(['dist']),   
]

而後報錯：TypeError: CleanWebpackPlugin is not a constructor

後來這樣寫：

const {CleanWebpackPlugin} = require("clean-webpack-plugin");

plugins:[
 new CleanWebpackPlugin(['dist']),   
]

繼續報錯：Error: clean-webpack-plugin only accepts an options object.

最後這樣寫：

const {CleanWebpackPlugin} = require("clean-webpack-plugin");

plugins:[
 new CleanWebpackPlugin(),   
]

 成功運行~

 

兩點：

一、new CleanWebpackPlugin()中不能寫參數，二、須要用{}
