今天安裝一些模組的時候發現 npm install 到了一個點之後就卡住了一樣等了半天一直不動，接著中斷看了下出現安裝出現了 UNMET DEPENDENCY 的 模組，這個時候如果重新 install 一便的話，又會重頭開始，如果又碰到卡殼就很煩。所以用list 命令檢視之後決定用另外一種解決方案來解決這個問題，即跑到缺失模組的目錄下去安裝：

D:\Users\Ls\AppData\Roaming\npm\node_modules\express\node_modules\connect>npm install uid2
...
D:\Users\Ls\AppData\Roaming\npm\node_modules\express\node_modules\connect>npm list -g

看 log 發現已經解決了一個 uid2 的依賴，剩下的依次類推，在該 connect 模組下手動 install 就可以解決這些 UNMET DEPENDENCY 的問題了。（用 sublime 拼一下很快的）
