Node 多版本管理：NVM

分类: IT文章 • 2023-12-16 12:29:13

安装前清理原有的 node，环境变量，缓存(e.g. "C:Users<user>AppDataRoaming pm*")

保存配置(e.g. C:Users<user>.npmrc & C:Users<user>AppDataRoaming pmetc.npmrc)

下载（有安装版与解压版，以解压为例）

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

解压后执行管理员方式执行 install.cmd，输入 NVM 解压的绝对路径即可。

脚本主要就是设置了环境变量，也可自己设置。设置完后会在 shell 的所在路径生成一个 settings.txt，记录路径。

NVM_HOME    D:PcAPPMVM
NVM_SYMLINK    C:Program Files
odejs
Path    %NVM_HOME%;%NVM_SYMLINK%

settings.txt

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

不设置的话可能会报如下错误

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

然后就可以使用了，在使用之前最好设置一下镜像源

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

常用命令

NVM for Windows is a command line tool. Simply type nvm in the console for help. The basic commands are:

  • nvm arch [32|64]: Show if node is running in 32 or 64 bit mode. Specify 32 or 64 to override the default architecture.
  • nvm install <version> [arch]: The version can be a node.js version or "latest" for the latest stable version. Optionally specify whether to install the 32 or 64 bit version (defaults to system arch). Set [arch] to "all" to install 32 AND 64 bit versions.
  • nvm list [available]: List the node.js installations. Type available at the end to show a list of versions available for download.
  • nvm on: Enable node.js version management.
  • nvm off: Disable node.js version management (does not uninstall anything).
  • nvm proxy [url]: Set a proxy to use for downloads. Leave [url] blank to see the current proxy. Set [url] to "none" to remove the proxy.
  • nvm uninstall <version>: Uninstall a specific version.
  • nvm use <version> [arch]: Switch to use the specified version. Optionally specify 32/64bit architecture. nvm use <arch> will continue using the selected version, but switch to 32/64 bit mode based on the value supplied to <arch>. For information about using use in a specific directory (or using .nvmrc), please refer to issue #16.
  • nvm root <path>: Set the directory where nvm should store different versions of node.js. If <path> is not set, the current root will be displayed.
  • nvm version: Displays the current running version of NVM for Windows.
  • nvm node_mirror <node_mirror_url>: Set the node mirror.People in China can use https://npm.taobao.org/mirrors/node/
  • nvm npm_mirror <npm_mirror_url>: Set the npm mirror.People in China can use https://npm.taobao.org/mirrors/npm/ 
# 显示已安装 node 版本
nvm ls

# 显示线上所有版本
 nvm ls available

# 显示 nvm 版本
nvm

# 安装指定版本
nvm install 14.6.0

# 安装最新稳定版
nvm install latest

# 使用指定版本(切换版本后，全局安装的需要重新安装)
nvm use 14.6.0

配置 npm 全局安装路径

npm config set prefix "D:
odejs
pm-global"

在 C:Users用户名 下会生成 .npmrc 文件，可以看到：prefix=D: odejs pm-global

设置 npm 源

npm config set registry https://registry.npm.taobao.org
