一、安装nvm

终端输入：

brew install nvm

安装完成后会出现提示：

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 “/opt/homebrew/opt/nvm/nvm.sh” ] && \. “/opt/homebrew/opt/nvm/nvm.sh”  # This loads nvm

[ -s “/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm” ] && \. “/opt/homebrew/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

/opt/homebrew/opt/nvm will destroy any nvm-installed Node installations

upon upgrade/reinstall.

Type `nvm help` for further information.

根据提示输入创建nvm目录：

mkdir ~/.nvm

编辑 ~/.zshrc 配置文件

①法一：直接在终端编辑（:wq 保存并退出）：

vi ~/.zshrc

②法二：找到对应的文件夹（更方便）

在 ~/.zshrc 配置文件后添加如下内容

export NVM_DIR="$HOME/.nvm"
 [ -s "/opt/homebrew/opt/nvm/nvm.sh" ] && . "/opt/homebrew/opt/nvm/nvm.sh" # This loads nvm
 [ -s "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" ] && . "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" # This loads nvm bash_completion

使用 source 命令使配置生效

source ~/.zshrc

查看配置是否生效

echo $NVM_DIR

查看帮助手册

nvm -help

Note:

to remove, delete, or uninstall nvm – just remove the `$NVM_DIR` folder (usually `~/.nvm`)

删除卸载nvm只需要移除$NVM_DIR文件夹，一般是~/.nvm

查看版本

nvm -v

nvm ls-remote // 查看所有的node可用版本

二、安装node

安装指定版本的node

nvm install 版本号

node -v

npm -v
