mac 安装 nvm官方文档：https://github.com/nvm-sh/nvm/blob/master/REA

两个二选一都可：

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

然后执行在终端执行nvm,若提示 zsh: command not found: node

执行下面

cd ~
//若有.zshrc 文件 直接 open .zshrc
//若无
 
touch ~/.zshrc

复制以下内容

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm关闭终端后执行

source ~/.zshrc
