使用Egg.js编写RestfulAPI接口（一）创建web工程

1.检查node是否已经安装

C:\Users\SYJ>node -v
v10.15.0

2.检查npm是否已经安装

C:\Users\SYJ>npm -v
6.14.11

3.创建并进入egg-example目录

C:\Users\SYJ>mkdir egg-example && cd egg-example

4.快速初始化egg标准web工程

C:\Users\SYJ\egg-example>npm init egg --type=simple

5.安装依赖

C:\Users\SYJ\egg-example>npm install

6.启动web工程，控制台显示启动成功，端口7001

C:\Users\SYJ\egg-example>npm run dev

> example@1.0.0 dev C:\Users\SYJ\egg-example
> egg-bin dev
