CleanWebpackPlugin is not a cons

今天在自行配置 webpack.config.js 文件时报了这样的错：TypeError: CleanWebpackPlugin is not a constructor
之后去官方文档看了看，发现是用法变了
以前引入是这样的：

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

现在应该这样引入：

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

总结：加一个花括号引入就可以了，其他不变
