前置说明：在研究别人的开源项目的时候，本地安装好项目依赖。
运行npm run start ,出现如下

- vue@2.5.2 (D:\IDEA_Work\fulingfront\node_modules\_vue@2.5.2@vue\dist\vue.runtime.common.js)
- vue-template-compiler@2.6.10 (D:\IDEA_Work\fulingfront\node_modules\_vue-template-compiler@2.6.10@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.

说明：从错误中，可以看到是由于Vue和vue-template-compiler的版本不匹配导致的

先删除文件夹node_modules文件夹下的vue-template-compiler文件 >cnpm install vue-template-compiler@2.5.2 --save-dev 再次运行 npm run start 即可
