=> Appending nvm source string to /root/.bashrc
=> Appending bash_completion source string to /root/.bashrc
=> 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

查看版本

1 2	[root@ol75elk74s ~]# nvm --version 0.35.0

通过git安装

NVM环境变量

如果是以root用户安装，默认被修改的配置文件如下表

操作系统	运行的用户	相对安装路径	实际安装路径	说明
Oracle Linux 7.5	root	~/.nvm	/root/.nvm	安装目录
Oracle Linux 7.5	root	~/.bash_profile, ~/.zshrc, ~/.profile, 或 ~/.bashrc	/root/.bashrc	配置文件

~/.bashrc即/root/.bashrc会被添加如下环境变量

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
