安裝node.js
推薦使用Homebrew安裝node.js:
brew install node
筆者這里使用官網(wǎng)pkg安裝出了點問題省艳，卸載時就很麻煩了，卸載pkg安裝的node.js參考鏈接：
How to Uninstall Node.js from Mac OSX
完成安裝之后檢查是否成功安裝：
kidneybro@macbookPro:~$ node -v
v11.10.0
kidneybro@macbookPro:~$ npm -v
6.7.0
kidneybro@macbookPro:~$ which npm
/usr/local/bin/npm
kidneybro@macbookPro:~$ which node
/usr/local/bin/node
安裝angular
使用cli命令安裝：
npm install -g @angular/cli
問題排查
筆者因為第一次安裝的時候出現(xiàn)問題缓呛，問題報錯整理如下：
kidneybro@macbookPro:~$ npm install -g @angular/cli
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules/@angular/cli

定位問題：
cd進入目錄/usr/local/lib/node_modules/有
kidneybro@macbookPro:~$ ll /usr/local/lib/node_modules
total 0

@angular目錄的創(chuàng)建者是root，故沒有權(quán)限操作，安裝失敗，刪除當(dāng)前@angular目錄即可盐肃，之后重新運行安裝指令有
kidneybro@macbookPro:~$ npm install -g @angular/cli
