yarn错误The engine "node" is incompatible with this module

 

今天在用yarn安装vue-cli时出现了错误

../vue-hackernews-2.0> yarn
yarn install v1.12.3
[1/5] Validating package.json...

error [email protected]: The engine "node" is incompatible with this module. Expected version ">=4 <=9". Got "10.14.2"

进行这个设置之后，会正常。 

 yarn config set ignore-engines true

但是这是什么原因那？

解析如下：

我的node.js安装包是8.2版本的，支持vue-cli 3.0版本以上需要v8.9以上

于是我去node.js官网下载了新版本，再次yarn add  g【page】 安装ok了。
