Error: clean-webpack-plugin only accepts an options object. 
TypeError: CleanWebpackPlugin is not a constructor

在使用webpack最新版本時 按照文檔操作居然報錯， 報錯提示為上面兩處。。

第一次這樣寫得， 報錯： TypeError: CleanWebpackPlugin is not a constructor

const CleanWebpackPlugin = require('clean-webpack-plugin');
plugins: [
    new CleanWebpackPlugin(['dist']),
  ],

解決方法：

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

第二次報錯：Error: clean-webpack-plugin only accepts an options object.
解決方法：

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

最后執行 npm run build 即成功可用了~
