在用vue-cli创建project时，

vue create project

出现了vue packages version mismatch的报错

/usr/local/lib/node_modules/@vue/cli/node_modules/vue-template-compiler/index.js:10
  throw new Error(
  ^

Error: 

Vue packages version mismatch:

- vue@2.5.13 (/node_modules/vue/dist/vue.runtime.common.js)
- vue-template-compiler@2.6.10 (/usr/local/lib/node_modules/@vue/cli/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.

一般的解决方法是更新vue到与vue-template-compiler同版本

npm install vue@2.6.10 --save

如果安装后还是出现相同的报错，有可能是vue的安装与运行环境不符，可尝试加上 `-g` 再装一遍

npm install vue@2.6.10 --save -g
