Calabash Android 런타임 오류 : 키 가드를 제거 할 수 없습니다.

테스트 서버를 시작할 때 아래 오류가 발생합니다. 내가 따랐던 단계는 다음과 같습니다.

1) calabash-android 사임 기능 \ com.whatsapp-v2.12.114-450480-Android-2.1.apk

2) calabash-android 빌드 기능 \ com.whatsapp-v2.12.114-450480-Android-2.1.apk

테스트 서버 서명을 완료했습니다. test_servers / 55a1d403d4a789d5d979742ac47bc35c_0.5.10.apk로 이동했습니다.

3) adb 장치

연결된 장치 목록 192.168.231.101:5555 장치

4) calabash-android 콘솔 기능 \ com.whatsapp-v2.12.114-450480-Android-2.1.apk

5) irb(main):001:0> start_test_server_in_background

그러면 아래 오류가 표시됩니다 .. 도와주세요.
