Error: EACCES: permission denied, access ‘/usr/local/lib/node_modules’
新换的笔记本，在安装yarn 的时候报错了， 错误如下图所示：

问题原因：
npm的错误提示已经指出了原因：Error: EACCES: permission denied （权限不够）
并给出了建议 ：Please try running this command again as root/Administrator.（使用管理员权限）
解决办法：
使用加上sudo的npm命令（sudo: 申请root 权限）
sudo npm install -g yarn
有时候就是英文不好，一直在想这要是外语好的人根本不叫事。看来学习外语真的需要提上日程了。
