Node.js ECONREFUSE错误无法安装npm

安装npm时出错。下面是节点及其依赖项

$ npm -v
2.7.4
$ node -v
v0.12.2
$ nvm list
->      v0.12.2
stable -> 0.12 (-> v0.12.2) (default)

这是完整的错误跟踪

我尝试卸载并重新安装。但它仍然可能发生。有任何答案吗？

尝试：npm安装--没有bin链接

显然

npm

无法连接到npm存储库。您是否配置了一个（在

~/.npmrc

中），您是在使用代理服务器还是在阻止传出网络连接？此回答没有提供任何解释，说明为什么这会提供解决方案。你能详细说明一下为什么会这样吗？
