webpack清理插件错误——TypeError: CleanWebpackPlugin is not a constructor

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

TypeError: CleanWebpackPlugin is not a constructor

以上两个错误属于同一个

之前这样写的：

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

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

然后报错：TypeError: CleanWebpackPlugin is not a constructor

后来这样写：

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

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

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

最后这样写：

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

plugins:[
 new CleanWebpackPlugin(),   
]

 成功运行~

两点：

1、new CleanWebpackPlugin()中不能写参数，
2、需要用{}
