我最近升级到 El Capitan，并打算升级到最新的 Kivy。按照OSX 安装说明后，我进入$/Applications/Kivy.app/Contents/MacOS/Kivy了终端，它崩溃并显示以下错误消息
2016-05-21 16:58:39.406 Kivy[29012:817803] NSDocumentController Info.plist warning: The values of CFBundleTypeRole entries must be 'Editor', 'Viewer', 'None', or 'Shell'.
2016-05-21 16:58:39.419 Kivy[29012:817803] Application did finish launching

出于兴趣，我打开了 Info.plist，CFBundleTypeRole 没有出现在任何地方。应该采取哪些步骤来让 Kivy 运行？
