Mac下,nvm安装Node及配置(copy文章)

    1. 安装nvm

    • 为了兼容性和效率,nvm和n进行Node版本管理很有必要,我选择使用nvm控制node版本。首先要说的是不能用brew去安装nvm,官方文档已经说明不支持,这里用以下命令安装:
    curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash
    
    
    • 此时nvm就被安装在了/.nvm下啦,接下来就需要配一下环境变量了,这里以zsh为例,在/.zshrc这个配置文件中配置,如果你的shell用的是bash或其它的,就找找看/.bash_profile或者/.profile,~/.bashrc。
    • 编辑器打开~/.zshrc文件,如果不会就输入open ~/.zshrc
    • 在最下面一行输入:
    export NVM_DIR="$HOME/.nvm"
    [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
    
    

    这一步的作用是每次新打开一个bash,nvm都会被自动添加到环境变量中了。

    • 完成后输入 source ~/.zshrc重新启动一下配置。
    • 输入nvm可以看到如下信息:
     zhao@EchodeMacBook-Pro  ~  source ~/.zshrc
     zhao@EchodeMacBook-Pro  ~  nvm
    Node Version Manager
    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`
    Usage:
      nvm help                                  Show this message
      nvm --version                             Print out the latest released version of nvm
      nvm install [-s] <version>                Download and install a <version>, [-s] from source. Uses .nvmrc if available
        --reinstall-packages-from=<version>     When installing, reinstall packages installed in <node|iojs|node version number>
      nvm uninstall <version>                   Uninstall a version
      nvm use [--silent] <version>              Modify PATH to use <version>. Uses .nvmrc if available
      nvm exec [--silent] <version> [<command>] Run <command> on <version>. Uses .nvmrc if available
      nvm run [--silent] <version> [<args>]     Run `node` on <version> with <args> as arguments. Uses .nvmrc if available
      nvm current                               Display currently activated version
      nvm ls                                    List installed versions
      nvm ls <version>                          List versions matching a given description
      nvm ls-remote                             List remote versions available for install
      nvm version <version>                     Resolve the given description to a single local version
      nvm version-remote <version>              Resolve the given description to a single remote version
      nvm deactivate                            Undo effects of `nvm` on current shell
      nvm alias [<pattern>]                     Show all aliases beginning with <pattern>
      nvm alias <name> <version>                Set an alias named <name> pointing to <version>
      nvm unalias <name>                        Deletes the alias named <name>
      nvm reinstall-packages <version>          Reinstall global `npm` packages contained in <version> to current version
      nvm unload                                Unload `nvm` from shell
      nvm which [<version>]                     Display path to installed node version. Uses .nvmrc if available
    Example:
      nvm install v0.10.32                  Install a specific version number
      nvm use 0.10                          Use the latest available 0.10.x release
      nvm run 0.10.32 app.js                Run app.js using node v0.10.32
      nvm exec 0.10.32 node app.js          Run `node app.js` with the PATH pointing to node v0.10.32
      nvm alias default 0.10.32             Set default node version on a shell
    Note:
      to remove, delete, or uninstall nvm - just remove the `$NVM_DIR` folder (usually `~/.nvm`)
    
    

    至此,nvm安装完成。

    2. 安装Node

    • 查看Node所有版本,用nvm ls-remote命令,如下:
      zhao@EchodeMacBook-Pro  ~  nvm ls-remote
            v0.1.14
            v0.1.15
            v0.1.16
            ...
             v7.7.1
             v7.7.2
             v7.7.3
    
    

    正常安装的话,会超级慢,如果想尝试,就用nvm install v6.10.0试试,不过这里推荐使用国内镜像:

    NVM_NODEJS_ORG_MIRROR=https://npm.taobao.org/mirrors/node nvm install 6
    
    

    需要哪个版本,就在最后将6换成对应的版本号就行,默认下载版本中最新的版本号。

    3. 切换Node版本

    没有常识,目前还没有需求,具体的可以参考如下链接:
