Rollup构建TS项目
安装依赖：
1.全局安装rollup npm install rollup-g
2.安装TypeScript npm install typescript -D
3.安装TypeScript 转换器 npm install rollup-plugin-typescript2 -D
4安装代码压缩插件 npm install rollup-plugin-terser -D
5 安装rollupweb服务 npm install rollup-plugin-serve -D
6 安装热更新 npm install rollup-plugin-livereload -D
7引入外部依赖 npm install rollup-plugin-node-resolve -D
8安装配置环境变量用来区分本地和生产 npm install cross-env -D
9替换环境变量给浏览器使用 npm install rollup-plugin-replace -D
配置json文件：
npm init -y
