为了让我的calabash运行，我需要debug.keystore文件来获得MD5指纹。我运行了以下命令：
keytool -list -alias androiddebugkey -keystore debug.keystore -storepass android -keypass android -v
但我并没有告诉我它创建了一个MD5指纹：
Alias name: androiddebugkey
Creation date: Nov 21, 2016
Entry type: PrivateKeyEntry
Certificate chain length: 1
Certificate[1]:

任何人都知道解决方案吗？
