A version string consists of a semantic version number or version label
("lts" or "latest"), optionally preceeded by a remote name, optionally
followed by an architecture, separated by slashes.
Examples: "lts", "4.6.0", "6.3.1/x86", "node/6.7.0/x64"
Aliases may also be used anywhere in place of a version string.
共用 npm 全局模块
使用 nvs 时，默认的 prefix 是当前激活的 Node.js 版本的安装路径。
带来一个问题是：切换版本之后，之前安装全局命令模块需要重新安装，非常不方便。
解决方案是配置统一的全局模块安装路径到 ~/.npm-global，如下：
$ mkdir -p ~/.npm-global
$ npm config set prefix ~/.npm-global
还需配置环境变量到 ~/.bashrc
echo "export PATH=~/.npm-global/bin:$PATH" >> ~/.bashrc
windows使用gitbash 事项
会出现找不到命令情况，应在.bash_profile加入以下命令
export NVS_HOME=$LOCALAPPDATA/nvs
. $NVS_HOME/nvs.sh
