nodeJS设置淘宝镜像

node.js安装

下载node.js安装包：https://nodejs.org/en/download/，下载相应版本的node.js.

需注意，在window中，node的安装目录中，最好不要有空格或中文字符。

nodeJS的资源仓库在国内使用过程中，偶尔会遇到各种资源问题，通常设置为淘宝的镜像，网上很多说法是安装淘宝镜像，即

$ npm install -g cnpm --registry=https://registry.npm.taobao.org

然后再用到npm install的时候，使用cnpm install进行安装node_modules。

但是该种方式，在集成到IED的时候，你如在IDEA中，如果想在IDEA中，直接使用node的命令，进行install，就行不通了。这个时候，可以使用第二种方式：

npm config set registry " https://registry.npm.taobao.org "

更改npm的config的registry 为淘宝镜像，然后再使用npm的时候，就是从淘宝镜像拉取数据了。

在更新node-sass中，有时候也会出现资源下载不了的问题，通常是git上的资源下载不了，这时候，可以更改node-sass的资源路径为淘宝的

npm config set sass_binary_site=https://npm.taobao.org/mirrors/node-sass/

phantomjs的源

npm config set phantomjs_cdnurl=https://npm.taobao.org/mirrors/phantomjs/

electron源

npm config set electron_mirror=https://npm.taobao.org/mirrors/electron/

2.4 设置全局安装目录

npm config set cache "D:\nodejs\node_cache"

npm config set prefix "D:\nodejs\node_global"

然后就可以愉快的使用cnpm安装工具了

3 常用命令集合

1. node -v #查看安装版本

2. npm -v #查看npm安装版本

3. npm config ls -l #查看配置项
