vue已经成功引入了,为什么还会报这个错呢, 我之前把vue2删了,换成了vue1.
报错内容:

ERROR  Failed to compile with 1 errors                                                                                                                                                                                    

This dependency was not found:

* vue in ./src/main.js

To install it, you can run: npm install --save vue
> Listening at http://localhost:8080

求解决啊~到底是什么问题
