rollup

• 1、@rollup/plugin-commonjs ：Since most packages in your node_modules folder are probably legacy CommonJS rather than JavaScript modules, you may need to use @rollup/plugin-commonjs:

• 2、@rollup/plugin-node-resolve：using third party modules in node_modules

• 3、@rollup/plugin-babel
  并且使用@rollup/plugin-commonjs
  babel({
  exclude: 'node_modules/**' // 解决打包后存在require 问题
  }),
  commonjs()
