安装npm。

npm的项目地址：https://github.com/creationix/nvm/blob/master/README.markdown

直接从Github中将git clone nvm到本地。

$ cd ~/git$ git clone https://github.com/cnpm/nvm.git

配置终端启动时自动执行 source ~/git/nvm/nvm.sh, 在 ~/.bashrc, ~/.bash_profile, ~/.profile, 或者 ~/.zshrc 文件添加以下命令:

source ~/git/nvm/nvm.sh

重新打开你的终端, 输入 nvm

```$ nvmNode Version Manager   Usage:nvm help                    Show this messagenvm --version               Print out the latest released version of nvmnvm install [-s]
