NodeJS安裝及全局配置

NodeJS安裝及全局配置

下載nodeJS

首先我們要到nodejs官網（https://nodejs.org）上下載node

查看版本

> node -v
v12.16.1
> npm -v
6.13.4

查看全局配置

> npm config ls

; cli configs
metrics-registry = "https://registry.npm.taobao.org/"
scope = ""
user-agent = "npm/6.13.4 node/v12.16.1 win32 x64"

; userconfig C:\Users\Administrator\.npmrc
cache = "D:\\Develop\\node-all-win-x64\\node_cache"
prefix = "D:\\Develop\\node-all-win-x64\\node_global"
registry = "https://registry.npm.taobao.org/"
registy = "https://registry.npm.taobao.org"

; node bin location = D:\Develop\node-v12.16.1-win-x64\node.exe
; cwd = C:\Users\Administrator
; HOME = C:\Users\Administrator
; "npm config ls -l" to show all defaults.

通過命令修改presfix和cache

進入cmd命令行，輸入一下的命令設置全局模塊的安裝路徑到node_global文件夾，緩存到node_cache文件夾：

> npm config set prefix "D:\Develop\nodejs\node_global"
> npm config set cache "D:\Develop\nodejs\node_cache"

node-sass/phantomjs/electron使用淘寶鏡像站

有些軟件包安裝的時候會下載已預編譯好的二進制格式，比如node-sass/phantomjs/electron等等，這幾個軟件包大多數都將編譯好的成品託管在S3上。

比較幸運的是這些軟件包都有辦法指定下載的路徑，有興趣的可以自己去讀這些包的安裝代碼，會去從環境變量或npmrc配置中讀取下載的路徑，這裏只貼出npmrc方案。同樣也適用於npm環境變量配置方案:

npm config set registry https://registry.npm.taobao.org/
npm config set disturl https://npm.taobao.org/dist/
npm config set electron_mirror https://npm.taobao.org/mirrors/electron/
npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/
npm config set phantomjs_cdnurl https://npm.taobao.org/mirrors/phantomjs/
npm config set chromedriver_cdnurl https://npm.taobao.org/mirrors/chromedriver/
npm config set operadriver_cdnurl https://npm.taobao.org/mirrors/operadriver/
npm config set python_mirror https://npm.taobao.org/mirrors/python/
npm config set electron_builder_binaries_mirror https://npm.taobao.org/mirrors/electron-builder-binaries/
npm config set node_sqlite3_binary_host_mirror https://npm.taobao.org/mirrors
