This may cause things to work incorrectly. Make sure to use the same version for both.

npm run serve运行报错：

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.

问题： 版本不统一

解决：

删除node_models 文件夹和 package-lock.json 文件重新 npm install
