前言

本文以Debian或者Ubuntu系统为例，CentOS的话，只需把apt换成yum即可。

更新相关系统包

在安装任何软件之前，通过apt在终端中运行以下命令来确保您的系统是最新的

sudo apt updatesudo apt upgrade

通用运行下面的命令来下载并运行 NVM 安装脚本

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

如果报找不到curl命令，则使用apt install curl进行安装

在.bashrc文件中添加环境变量

安装成功后，NVM会提示让你配置环境变量，如下：

root@junyang:~# curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                 Dload  Upload   Total   Spent    Left  Speed100 15916  100 15916    0     0  82895      0 --:--:-- --:--:-- --:--:-- 83329=> Downloading nvm from git to '/root/.nvm'=> Initialized empty Git repository in /root/.nvm/.git/=> Compressing and cleaning up git repository=> nvm source string already in /root/.bashrc=> bash_completion source string already in /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

编辑root目录下的.bashrc文件，把下面内容添加到文件中
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

重载.bashrc配置文件

source ~/.bashrc

查看NVM版本

nvm --version
