每次我尝试用 NPM 做某事时，它都不起作用。我已经安装了 nodeversion 0.10.7和 npm version 1.2.21。我需要安装咖啡脚本，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

我看到了这个链接： 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
后来在那篇文章中，有人说要更改令牌/usr/local/etc/npmrc但我没有那个文件。之后我将节点更新为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。
已编辑的问题：我已删除npm proxy并且npm https-proxy现在已安装咖啡脚本，但显示了一些警告
sudo npm install -g 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？
