更換淘寶鏡像，加速node下載。
1、添加環境變量：
NODIST_NODE_MIRROR 值：https://npm.taobao.org/mirrors/node
NODIST_IOJS_MIRROR 值：https://npm.taobao.org/mirrors/iojs
2、npm加速。打開命令行窗口，輸入命令：
npm config set registry https://registry.npm.taobao.org
3、常用命令：
nodist //查看當前安裝了的node版本列表
nodist 4.4.6 //設置全局node的版本，如果該版本不存在，會先下載
nodist + 4.4.6 //檢查該版本有沒有安裝，如果沒有，會進行下載
nodist -4.4.6 //移除某個版本
nodist npm list // 查看所有已安裝的npm版本
nodist npm match // 切換到匹配當前node版本的npm版本（沒有則下載）
nodist npm 3.10.5 // 安裝npm 3.10.5版本
