cross-env vue的版本

laravel 

npm run dev 报错 spawn ENOENT

方法：npm install cross-env

继续报新的错误

Vue packages version mismatch:

- vue@2.4.4

- vue-template-compiler@2.5.2

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.

方法：npm install vue-loader

+ vue-loader@13.3.0 会自动被加入package.json的dependencies

npm install vue-template-compiler

+ vue-template-compiler@2.5.9 

再跑npm run dev，看看有什么问题

哎呀还是同样的错误

把vue-template-compiler的版本改成和vue的版本一样

"vue": "2.4.4"

vue-template-compiler": "2.4.4"

npm update vue-template-compiler

终于可以了
