Question

当我尝试使用npm进行安装时，出现以下控制台文字

 guilherme@guilherme-Aspire-A515-52G:~$  npm install -g react-native-cli  npm WARN checkPermissions Missing write access to /usr/local/lib npm ERR! code EACCES npm ERR! syscall access npm ERR! path /usr/local/lib npm ERR! errno -13 npm ERR!

所以我尝试使用yarn并可以工作，但不能100％因为，这一次我写

react-native init myProject

我收到如下错误：

找不到返回命令！

任何对此的帮助将不胜感激。
