node.js npm 设置http代理

node.js 的npm命令是node.js的包管理工具,安装外部模块时只需npm install packagname 即可,但是对于上网时使用代理的却安装不了:

F:\node.js\learn>npm install formidable
npm http GET http://registry.npmjs.vitecho.com/formidable

对于此种情况只需设置一下npm的环境变量就可以了,只可惜官方说明不是很详细,我在github上问了之后才得到答案。运行如下命令:
npm config set proxy=http://192.168.1.1:8080
就可以了,但是看官方的文档中明明有http_proxy、https_proxy两个变量,设置了却不起作用。
