npm err ( create-react-app 出错了)!! 大爷快来啊

Question

全局安装create-react-app后，创建项目出的错，之前想怎么玩怎么玩，现在懵逼了，node重装了也没用,create-react-app卸了重新全局安装也没用,日志也看不出所以然

报错

设置npm代理,执行命令

npm config set registry http://registry.cnpmjs.org

然后重新create项目

create-react-app my-app
    ...
    Happy hacking!
//完成了...

之前用的淘宝代理

npm config set registry https://registry.npm.taobao.org

装任何东西都ok，create-react-app也没问题，今天就突然挂掉了,只挂这一个啊,换回来居然就好了，无语！
