linux 下安装nvm

nvm是nodejs的版本管理工具，用于切换nodejs版本

在windows下使用exe安装包安装，linux下则使用脚本安装

1、下载安装脚本

https://github.com/nvm-sh/nvm/blob/master/install.sh

2、执行install.sh文件

./install.sh 
 

=> Downloading nvm from git to '/root/.nvm'
=> 正克隆到 '/root/.nvm'...

=> Compressing and cleaning up git repository

=> Appending nvm source string to /root/.bashrc
=> Appending bash_completion source string to /root/.bashrc
=> You currently have modules installed globally with `npm`. These will no
=> longer be linked to the active version of Node when you install a new node
=> with `nvm`; and they may (depending on how you construct your `$PATH`)
=> override the binaries of modules installed with `nvm`:

/data/nodejs/lib
├── forever@3.0.4
=> If you wish to uninstall them at a later point (or re-install them under your
=> `nvm` Nodes), you can remove them from the system Node as follows:

     $ nvm use system
     $ npm uninstall -g a_module

=> 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
 

3、source ~/.bashrc

然后执行 source ~/.bashrc命令   nvm -v 查看版本完成
