安裝前清理原有的 node，環境變數，快取(e.g. "C:\Users\<user>\AppData\Roaming\npm*")

儲存配置(e.g. C:\Users\<user>\.npmrc;C:\Users\<user>\AppData\Roaming\npm\etc\.npmrc)

下載（有安裝版與解壓版，以解壓為例）

https://github.com/coreybutler/nvm-windows/releases

解壓後執行管理員方式執行install.cmd，輸入 MVN 解壓的絕對路徑即可。

指令碼主要就是設定了環境變數，也可自己設定。設定完後會在 shell 的所在路徑生成一個settings.txt，記錄路徑。

NVM_HOME    D:\PcAPP\MVM
NVM_SYMLINK    C:\Program Files\nodejs
Path    %NVM_HOME%;%NVM_SYMLINK%

settings.txt

root: D:\PcAPP\MVM
arch: 64
proxy: none
originalpath: .
originalversion: 
node_mirror: https://npm.taobao.org/mirrors/node/
npm_mirror: https://npm.taobao.org/mirrors/npm/

不設定的話可能會報如下錯誤

ERROR open \settings.txt: The system cannot find the file specified.

然後就可以使用了，在使用之前最好設定一下映象源

nvm node_mirror https://npm.taobao.org/mirrors/node/
nvm npm_mirror https://npm.taobao.org/mirrors/npm/

# 顯示已安裝 node 版本
nvm ls

# 顯示線上所有版本
 nvm ls available

# 顯示 nvm 版本
nvm

# 安裝指定版本
nvm install 14.6.0

# 安裝最新穩定版
nvm install latest

# 使用指定版本(切換版本後，全域性安裝的需要重新安裝)
nvm use 14.6.0

配置 npm 全域性安裝路徑

npm config set prefix "D:\nodejs\npm-global"

在 C:\Users\使用者名稱\ 下會生成 .npmrc 檔案，可以看到：prefix=D:\nodejs\npm-global
