Ich versuche, die chaincode_example02 von IBM zu arbeiten, aber ich mit einigen Fragen habe SchwierigkeitenBluemix: Fehler: Fehler chaincode spec starten (kann nicht Deployment-Transaktion erhält für
ich verbunden mit einem Bluemix Starter Netzwerk. . mehr habe ich gewartet, ohne Erfolg abzufragen, aber jetzt habe ich das Peer-Protokoll lese und ich habe folgende Fragen:.
muss I/hinzufügen importieren Sie die Peer und Shim von meinem lokalen unterwegs Arbeitsverzeichnis?
Was d oes die
