IDEA启动时报错：
Module build failed: Error:
Vue packages version mismatch:
- vue@2.6.10
- vue-template-compiler@2.5.16
This may cause things to work incorrectly. Make sure to use the same version for both.
If you are using vue-loader@>=10.0, simply update vue-template-compiler.
If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.
at Object.<anonymous> (I:\Project\LeYou\leyou-manage-web\node_modules\vue-template-compiler\index.js:8:9)
错误原因：
版本冲突
解决方法：
npm install vue@2.5.16 --save
再重新启动：
npm run dev
完美解决问题！
