安装

安装 nvm

使用 brew 安装比较方便，更新一下 Homebrew 并安装

% brew update % brew install nvm ... ... ... You should create NVM's working directory if it doesn't exist:    mkdir ~/.nvm  Add the following to ~/.zshrc or your desired shell configuration file:    export NVM_DIR="$HOME/.nvm"   [ -s "/usr/local/opt/nvm/nvm.sh" ] && . "/usr/local/opt/nvm/nvm.sh"  # This loads nvm   [ -s "/usr/local/opt/nvm/etc/bash_completion.d/nvm" ] && . "/usr/local/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion  You can set $NVM_DIR to any location, but leaving it unchanged from /usr/local/opt/nvm will destroy any nvm-installed Node installations upon upgrade/reinstall.  Type `nvm help` for further information.  Bash completion has been installed to:   /usr/local/etc/bash_completion.d ==> Summary ?  /usr/local/Cellar/nvm/0.35.3: 7 files, 150.0KB, built in 2 seconds 

根据提示，创建 .nvm 目录

% mkdir ~/.nvm 

编辑 ~/.zshrc 配置文件

% vi ~/.zshrc 

在 ~/.zshrc 配置文件后添加如下内容

export NVM_DIR="$HOME/.nvm" [ -s "/usr/local/opt/nvm/nvm.sh" ] && . "/usr/local/opt/nvm/nvm.sh" [ -s "/usr/local/opt/nvm/etc/bash_completion.d/nvm" ] && . "/usr/local/opt/nvm/etc/bash_completion.d/nvm" 

:wq 保存并退出。

使用 :wq 命令使配置生效

% source ~/.zshrc 

查看一下配置是否生效

% echo $NVM_DIR /Users/your-username/.nvm 

查看帮助

% nvm --help ... ... Note:   to remove, delete, or uninstall nvm - just remove the `$NVM_DIR` folder (usually `~/.nvm`) 

帮助的最后一句话，可以看到删除 nvm 很简单，只要删除 $NVM_DIR 文件夹既可以

安装 node.js

查看 node.js 版本可以使用如下命令

% nvm ls-remote 

可以看到很多版本，接下来安装 LTS 版本

% nvm install 16 Downloading and installing node v16.20.1... ... Computing checksum with shasum -a 256 Checksums matched! 

安装完之后，可以查看一下

% nvm ls ->     v16.20.1 default -> 16 (-> v16.20.1) iojs -> N/A (default) unstable -> N/A (default) node -> stable (-> v18.17.0) (default) stable -> 18.17 (-> v18.17.0) (default) lts/* -> lts/hydrogen (-> v18.17.0) lts/argon -> v4.9.1 (-> N/A) lts/boron -> v6.17.1 (-> N/A) lts/carbon -> v8.17.0 (-> N/A) lts/dubnium -> v10.24.1 (-> N/A) lts/erbium -> v12.22.12 (-> N/A) lts/fermium -> v14.21.3 (-> N/A) lts/gallium -> v16.20.1 

可以看到，安装的是 v16 的稳定版。因为只安装了一个版本，所以使用的版本是 v16
使用其他版本(建议安装稳定版本), 本例安装 v18 的稳定版为例

% nvm install 18 Downloading and installing node v18.17.0... ... Computing checksum with shasum -a 256 Checksums matched! 

可以看到当前 node 版本改为 v18

% nvm ls        v16.20.1 ->     v18.17.0 default -> 16 (-> v16.20.1) iojs -> N/A (default) unstable -> N/A (default) node -> stable (-> v18.17.0) (default) stable -> 18.17 (-> v18.17.0) (default) lts/* -> lts/hydrogen (-> v18.17.0) lts/argon -> v4.9.1 (-> N/A) lts/boron -> v6.17.1 (-> N/A) lts/carbon -> v8.17.0 (-> N/A) lts/dubnium -> v10.24.1 (-> N/A) lts/erbium -> v12.22.12 (-> N/A) lts/fermium -> v14.21.3 (-> N/A) lts/gallium -> v16.20.1 lts/hydrogen -> v18.17.0 

切换默认的版本

% nvm use 18 Now using node v18.17.0 (npm v9.6.7) 

查看一下版本

% node -v v18.17.0
