我是一個紅寶石和RoR新手，在我的本地機器上工作正常。我GIT推，然後拉到另一臺機器，現在我收到此錯誤標題Errno :: ENOENT在ArtsController＃創建
Errno::ENOENT in ArtsController#create
Extracted source (around line #29):

28 def create
29 @art = Art.new(art_params)

謝謝大家提前。
也許你沒有在那裏你想保存第二臺機器上的目錄？ – zrl3dx
但問題是在第29行與art_params。另外，我相信art.save只是一個布爾值，用於顯示內容是否已成功上載所有必需的信息字段。 – user1452494
的確，但是'Errno :: ENOENT'類似文件系統錯誤，'new'只在內存中創建對象。 – zrl3dx
