安装完之后查看版本

// 安装指定版本的node
nvm install 20.11.0
// 查看当前已安装的node
nvm ls
// 使用指定版本的node
nvm use xxx

得到如下结果

C:\Users\fir>nvm install 20.11.0
Downloading node.js version 20.11.0 (64-bit)...
Extracting node and npm...
Complete
npm v10.2.4 installed successfully.


Installation complete. If you want to use this version, type

nvm use 20.11.0

C:\Users\fir>nvm ls

    20.11.0
    
C:\Users\fir>nvm use 20.11.0
Now using node v20.11.0 (64-bit)

C:\Users\fir>nvm ls

  * 20.11.0 (Currently using 64-bit executable)

查看镜像源与npm所有配置

// 查看当前当前版本镜像源
npm get registry
// 查看当放前所有配置
npm config ls

得到如下结果

C:\Users\fir>npm get registry
https://registry.npmjs.org/

C:\Users\fir>npm config ls
; node bin location = D:\Application\work\nodejs\node.exe
; node version = v20.11.0
; npm local prefix = C:\Users\fir
; npm version = 10.2.4
; cwd = C:\Users\fir
; HOME = C:\Users\fir
; Run `npm config ls -l` to show all defaults.

修改镜像源与npm配置

创建node_cache与node_global文件夹(本文安装在nvm同级目录下)

node_cache
node_global

C:\Users\fir>npm get registry
http://registry.npm.taobao.org/

C:\Users\fir>npm config ls
; "user" config from C:\Users\fir\.npmrc

cache = "D:\\Application\\work\\nvm\\node_cache"
prefix = "D:\\Application\\work\\nvm\\node_global"
registry = "http://registry.npm.taobao.org"

; node bin location = D:\Application\work\nodejs\node.exe
; node version = v20.11.0
; npm local prefix = C:\Users\fir
; npm version = 10.2.4
; cwd = C:\Users\fir
; HOME = C:\Users\fir
; Run `npm config ls -l` to show all defaults.

安装其他版本

C:\Users\fir>nvm install 18.19.0
Downloading node.js version 18.19.0 (64-bit)...
Extracting node and npm...
Complete
npm v10.2.3 installed successfully.


Installation complete. If you want to use this version, type

nvm use 18.19.0
C:\Users\fir>nvm ls

  * 20.11.0 (Currently using 64-bit executable)
    18.19.0
    
C:\Users\fir>nvm use 18.19.0
Now using node v18.19.0 (64-bit)
C:\Users\fir>nvm ls

    20.11.0
  * 18.19.0 (Currently using 64-bit executable)

此时再查看npm配置，可知，即使切换版本，配置依然生效

C:\Users\fir>npm get registry
http://registry.npm.taobao.org/

C:\Users\fir>npm config ls
; "user" config from C:\Users\fir\.npmrc

cache = "D:\\Application\\work\\nvm\\node_cache"
prefix = "D:\\Application\\work\\nvm\\node_global"
registry = "http://registry.npm.taobao.org"

; node bin location = D:\Application\work\nodejs\node.exe
; node version = v18.19.0
; npm local prefix = C:\Users\fir
; npm version = 10.2.3
; cwd = C:\Users\fir
; HOME = C:\Users\fir
; Run `npm config ls -l` to show all defaults.

安装结束

node文件都将在nvm同级目录下
