Mac NVM 配置

1、NVM 简介

  • NVM(node version manager)是一个可以让你在同一台机器上安装和切换不同版本 node 的工具。

  • GitHub 地址

2、NVM 环境配置

2.1 安装 NVM

  • 如果系统没有安装 git 的话,需先安装 git

  • 在终端输入以下命令安装 NVM。

    # 安装 NVM
    $ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
  • 安装完成后在终端中输入以下命令配置环境变量。

    # 打开环境变量配置文件
    $ vim ~/.bash_profile
  • 在 .bash_profile 文件中添加一下字段。

    source ~/.bashrc
  • 保存文件退出,在终端中输入以下命令使配置生效。

    # 使环境变量配置生效
    $ source ~/.bash_profile

2.2 NVM 常用命令

  • 常用命令

    # 查看该系统已经安装的版本,这个命令也能看到当前使用的是哪个版本
    $ nvm ls
    
    # 列出全部可以安装的版本号
    $ nvm ls-remote
    
    # 安装指定版本
    $ nvm install [version]
    $ nvm install v10.2.0
    
    # 切换到指定版本,切换效果是全局的
    $ nvm use [version]
    $ nvm use v10.2.0
    
    # 查看当前使用的版本
    $ nvm current
    Note: <version> refers to any version-like string nvm understands. This includes:
      - full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
      - default (built-in) aliases: node, stable, unstable, iojs, system
      - custom aliases you define with `nvm alias foo`
    
     Any options that produce colorized output should respect the `--no-colors` option.
