node.js - Npm 肯定不行

Question

每次我尝试用 NPM 做某事时，它都不起作用。我用 version 0.10.7 安装了 Node 和 npm version 1.2.21 .我需要安装 CoffeeScript ，它给了我这个错误:

npm http GET https://registry.npmjs.org/coffee-script
npm http GET https://registry.npmjs.org/coffee-script
npm http GET https://registry.npmjs.org/coffee-script
npm ERR! network tunneling socket could not be established, cause=getaddrinfo ENOTFOUND
npm ERR! network This is most likely not a problem with npm itself
npm ERR! network and is related to network connectivity.
npm ERR! network In most cases you are behind a proxy or have bad network settings.

npm ERR! network 'proxy' config is set properly.  See: 'npm help config'

我看过这个链接:
https://github.com/isaacs/npm/issues/2677
但是在我尝试检查代理后，我得到了这个:

~ > npm config get proxy
proxy-url:port
~ > npm config get https-proxy
proxy-url:port

后来在那篇帖子中，有人说要在 /usr/local/etc/npmrc 更改 token 但我没有那个文件。之后我将 Node 更新为 v0.10.18但我仍然有同样的错误。我正在使用 Ubuntu 12.04，但我仍然不知道如何解决这个问题。请帮忙。

编辑问题:
我已删除 npm proxy和 npm https-proxy现在已经安装了coffeescript，但显示了一些警告

sudo npm install -g coffee-script
npm http GET https://registry.npmjs.org/coffee-script
npm http 200 https://registry.npmjs.org/coffee-script

在我输入咖啡后，它就存在并给了我 REPL 提示。即使在安装时出现这些警告，这是否仍能正常工作？

解决方案在这里:

Manually installing NPM packages

npm set proxy $PROXY
npm set https-proxy $PROXY
