This dependency was not found: * @/component/firstPage in ./src/router/index.js To install it

vue运行出现这个error：

This dependency was not found:

* @/component/firstPage in ./src/router/index.js

To install it, you can run: npm install --save @/component/firstPage    

原来是我把页面删了，解决这个方法有两个：

1、添加firstPage  页面

2、去/src/router/index.js里把相应的route去掉。
