訪問Nodist主頁，下載安裝包，安裝好軟件。注：如果電腦之前安裝了Node，安裝Nodist之前需要卸載掉Node；

更換淘寶鏡像，加速node下載。

1、添加環(huán)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(dāng)前安裝了的node版本列表
 nodist 4.4.6 //設(shè)置全局node的版本，如果該版本不存在，會(huì)先下載
 nodist + 4.4.6 //檢查該版本有沒有安裝，如果沒有，會(huì)進(jìn)行下載
 nodist -4.4.6 //移除某個(gè)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(dāng)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

使用說明

Usage:

nodist                          List all installed node versions.
nodist list

nodist dist                     List all available node versions.
nodist ds

nodist add <version>            Download the specified node version.

nodist <version>                Use the specified node version globally
nodist global <version>         (downloads the executable, if necessary).

nodist local <version>          Use <version> in this directory and its subdirectories.
                                (will add a ./node-version file)

nodist use <version>            Use <version> in the current environment only
nodist env <version>            (usually the current terminal window).

nodist run <version> -- <args..>    Run <args> with the specified node version
nodist r <version> -- <args..>      (downloads the executable, if necessary).

nodist bin <version>            Get the path to the specified node executable

                                (Get yourself a cuppa in the meantime...)
