Error:

Vue packages version mismatch:

- vue@2.5.13 (C:\Users\DELL\node_modules\vue\dist\vue.runtime.common.js)
- vue-template-compiler@2.6.11 (C:\Users\DELL\AppData\Local\Yarn\Data\global\node_modules\vue-template-compiler\package.json)

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.

将vue的版本改成和vue-template-compiler@2.6.11 一样即可

npm install vue@2.6.11 --save
