切换到 projectName 这个目录，启动即可：
$ cd projectName
$ npm start
访问项目
如果启动没有任何异常的话，直接在浏览器访问 http://localhost:8080 即可看到效果了。
[!TIP]
使用 npx 命令，要求 npm 的版本 > 5.2.0，如果不会使用 npx 命令可以按下述方式进行安装
$ npm i es10-cli -g
$ es10-cli create projectName
$ cd projectName
$ npm start
如果项目安装失败，请手动下载模板并安装：
git clone https://github.com/cucygh/es-cli.git
cd es-cli
npm install
npm start
三个方法都试过了，1和2 安装失败，第三个显示‘[nodemon] app crashed - waiting for file changes before starting…
’就不动了。求救
