直接 npm install -g @vue/cli全域性安裝是會出現錯誤

npm全域性安裝檔案時可以使用 ‘sudo’ 任何管理員賬戶都可以使用sudo來獲取 root 許可權。
使用 sudo npm install -g @vue/cli 進行安裝
1、輸入安裝命令後，命令提醒你輸入Password密碼，目的使用管理員許可權去安裝

asusdeMac:~ asus$ sudo npm install -g @vue/cli
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
Password:密碼輸入完後稍等一會兒就安裝成功啦！
