nodejs npm包管理的配置方法及常用命令介紹

1. 輸入 npm config ls -l 可以查看當前的目錄設定
複製代碼 代碼如下:
; cli configs
long = true

; builtin config C:\Program Files (x86)\nodejs\node_modules\npm\npmrc
prefix = "C:\\Users\\sam\\AppData\\Roaming\\npm"

; default values
always-auth = false

2. 針對某一項設定，可以通過
複製代碼 代碼如下:
npm config set 屬性名稱 屬性值

的方式來進行配置。

例如:
複製代碼 代碼如下:npm config set prefix "C:\123\"

3. 讀取某一項配置
複製代碼 代碼如下:npm config get prefix

4.npm的常用命令
複製代碼 代碼如下:
npm install xxx 安裝模組
npm install xxx@1.1.1   安裝1.1.1版本的xxx
npm install xxx -g 將模組安裝到全域環境中。
npm ls 查看安裝的模組及依賴
npm ls -g 查看全域安裝的模組及依賴
npm uninstall xxx  (-g) 卸載模組
npm cache clean 清理緩衝
npm help xxx  查看協助
npm view moudleName dependencies  查看包的依賴關係
npm view moduleNames  查看node模組的package.json檔案夾
npm view moduleName labelName  查看package.json檔案夾下某個標籤的內容
npm view moduleName repository.url  查看包的源檔案地址
npm view moduleName engines   查看包所依賴的Node的版本
npm help folders   查看npm使用的所有檔案夾
npm rebuild moduleName    用於更改包內容後進行重建
npm outdated   檢查包是否已經過時，此命令會列出所有已經過時的包，可以及時進行包的更新
npm update moduleName   更新node模組
