I'm trying to figure Ruby on Rails in cygwin, and I;ve used the native cygwin installer, however I get this error message when I try
$ gem install rails. I've also tried another route with RailInstaller and but I don't think Cygwin can locate the correct path.
//錯誤信息 大廈原生擴展。這可能需要一段時間... 錯誤：安裝rails的錯誤： 錯誤：無法構建gem本機擴展。麻煩Cygwin中安裝滑軌

它說它找不到密碼庫。您可能需要從Cygwin安裝程序安裝crypt版本。 – Casper
嗨卡斯帕，感謝您的幫助，我下載了crypt dev版本，但我仍然得到相同的找不到-lcrypt錯誤，有什麼想法？ – google1254
發現了正確的地穴，還有一些錯誤，但我會一一瀏覽它們。謝謝！ – google1254
