root 权限

curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
source ~/.bashrc

非root权限

cd ~ && git clone https://github.com/nvm-sh/nvm.git .nvm
cd ~/.nvm && git checkout v0.40.1

手动添加环境变量

• vim ~/.bashrc

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

简单使用

nvm ls-remote # 查看可用的node版本列表
nvm install vv20.18.1 # 安装指定版本的node
nvm use vv20.18.1 # 切换到指定版本的node
nvm uninstall vv20.18.1 # 卸载指定版本的node
