npm依赖关系parsing – 或 – 帮助！ 我不能安装derbyjs
我一直在试图安装Derby，并且npm坚持不能find合适的express版本。 这是我使用的命令： npm install -g derby 。 以下是输出。 我正在运行Ubuntu 11.10，节点v0.7.6和npm v1.1.17。 难道我做错了什么？ 我怎样才能解决这个问题？

Derby需要express v2.x，并且表示v2.x需要节点v0.4.1 => 0.7.0-pre。 这意味着npm将无法find有效的express版本，因为您的节点版本v0.7.6不受支持。
你最好的select是降级Node。 你也可以手动安装express，并希望它实际兼容，但这可能是一个坏主意。
