mac下安装nvm的node版本管理工具

背景：由于电脑中装了好几个前端vue项目，但是每个vue项目都依赖不同的node版本，所以打算安装一个node版本控制工具来随时切换node的版本

下载nvm的网址

下载nvm的命令

javascript 复制代码

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash                                                       INT|INT ✘  base Py  at 13:47:26

=> Appending nvm source string to /Users/wuzhanxi/.zshrc
=> Appending bash_completion source string to /Users/wuzhanxi/.zshrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

仔细看上面的输出，它将相应的配置放到下面的文件中 /Users/wuzhanxi/.zshrc

javascript 复制代码

cat /Users/wuzhanxi/.zshrc

但是这会儿在终端下执行nvm的命令，会提示该命令不生效

javascript 复制代码

 ~/Desktop  nvm                                                                                                                                       127 ✘  base Py  at 13:50:03 
zsh: command not found: nvm

原因是上面的配置文件没有生效，解决方案，执行下面的命令，让配置文件立即生效

javascript 复制代码

source /Users/wuzhanxi/.zshrc

然后再次执行nvm即可

javascript 复制代码

nvm

展示远程上的可用node版本

javascript 复制代码

nvm list-remote

安装特定版本的node

javascript 复制代码

nvm install 16.17.1                                                                                                                         3 ✘  base Py  at 14:11:16

展示已经安装的node版本

javascript 复制代码

nvm list

使用特定的node版本

javascript 复制代码

nvm use xxx

设置默认的node版本

javascript 复制代码

nvm alias default 16.17.1

查看当前使用的node版本

javascript 复制代码

 node -v

有疑问，输入展示可用的node版本列表后，显示以下两种不同的效果

nvm list-remote

javascript 复制代码

       v16.11.0
       v16.11.1
