昨天在拉代码下来安装依赖成功后，对项目进行编译启动，结果报错了，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.，再一看发现是因为vue的版本和vue-template-compiler的版本不一样，vue是[email protected]版本，vue-template-compiler是[email protected]版本。

一、报错

Vue packages version mismatch:

- [email protected] (E:\项目xxx-mobile\node_modules\vue\dist\vue.runtime.common.js)
- [email protected] (E:\项目\xxx-mobile\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.

二、解决方法

  将 vue的版本 和 vue-template-compiler的版本改成一致

	npm i [email protected] --save

建议先将原来的 vue-template-compiler 删除，再重新进行安装
