解決方案：
官方的解決方案：https://docs.npmjs.com/getting-started/fixing-npm-permissions

官方提供了兩種解決方案：

重新安裝一個node version manager慰照。（官方推薦）
參考地址：https://docs.npmjs.com/getting-started/installing-node

注：這個方法比較繁瑣歧焦，我選擇的是第二種方案叉跛。
2.改變npm默認的路徑组橄。
步驟如下：
進入終端变过，依次輸入一下命令
（1）創(chuàng)建global安裝任務的目錄
mkdir ~/.npm-global
（2）配置npm使用新的目錄
npm config set prefix '~/.npm-global'
（3）在~/.profile文件中增加配置
export PATH=~/.npm-global/bin:$PATH
（4）配置文件立即生效
source ~/.profile （也可以不執(zhí)行）
（5）重新執(zhí)行命令
npm link 完美解決
