我在ubuntu上使用npm v1.0.104 / node
0.6.12-在尝试通过npm安装任何新模块时收到以下复制的错误（我之前使用http而不是https测试了socket.io，但我想知道是否可以导致npm
/ unsigned证书出现问题）。一旦npm尝试解析“
https://registry.npmjs.org ”
URL，该错误就会弹出。无论如何，我可以忽略该错误，或​​者定位/将证书添加到受信任的存储中以便继续使用npm。

对于解决该问题需要做什么的任何见解将不胜感激（我更愿意通过配置解决问题，而不是尽可能重新安装）。

错误：“错误：SSL错误：SELF_SIGNED_CERT_IN_CHAIN”
