然后在终端输入npm run dev的时候，提示错误信息：
$ npm run dev

一般这种错误发生在vue.config.js中
从上往下查找，发现Proxy大写了也会出错！
devServer: {
port: port,
open: true,
overlay: {
warnings: false,
errors: true
},
Proxy: {
'/api': {
target: 'http://ihrm-java.itheima.net/', // 要代理的地址
changeOrigin: true // 是否跨域
}
}
// before: require("./mock/mock-server.js")
},此时再重新npm run dev

Note that the development build is not optimized.
