vue运行项目报错，完整错误信息如下：

FATAL                                                                                    20:56:01
Vue packages version mismatch:
- vue@2.7.14
- vue-server-renderer@2.6.11
This may cause things to work incorrectly. Make sure to use the same version for both.

从报错信息中可以看出，错误为两者的版本不匹配。

解决办法：

//1、vue去配合vue-server-renderer的版本
npm install vue@2.6.11 --save
//2、vue-server-renderer去配合vue的版本
npm install vue-server-renderer@2.7.14 --save

注：修改其中一个匹配另一个版本即可。
