首先查看node镜像安装路径

which node

    返回nvm正确变量示例：/home/username/.nvm/versions/node/v18.16.0/bin/node

部署nvm

 curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash   

添加环境变量:

vim ~/.zshrc

        window按i进入编写模式

        Mac按E进入编写模式

 末尾添加:

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"   

        Mac电脑按 control+c  后根据提示:qa!退出 window电脑按esc输入:wq!退出

然后重载一次配置就可以使用 nvm 运行适合当前环境的命令

source ~/.zshrc
/Users/tong/.zshrc:5: bad assignment

再次查看镜像是否改变

which node

返回nvm正确环境为 :/home/username/.nvm/versions/node/v18.16.0/bin/node
