Versuchen, eine Bereitstellungsdatei für AWS Lambda

Question

zu erstellen Ich versuche, eine Alexa-Fähigkeit zu erstellen, die mir sagt, wann die nächste Zugzeit an meinem Bahnhof ist. Ich möchte ein Paket mit dem Namen pygtfs verwenden, bei dem es sich um eine Bibliothek handelt, die Informationen im GTFS-Format (General Transit Feed Specification) von Google darstellt. Ich habe die Dateien, die das JSON-Objekt von Alexa verarbeitet und sie funktionieren gut. Ich habe Probleme, ein Zip-Bereitstellungspaket zum Hochladen auf aws lambda zu erstellen. Ich habe ein Python-Skript, das ein Bereitstellungspaket erstellt, aber ich erhalte einen Fehler. Der Fehler fügt dem Bereitstellungspaket nicht die richtigen Dateien hinzu.

def _copy_deployment_files(deployment_dir): 
    for deployment_file in deployment_files: 
     if os.path.exists(deployment_file): 
      cmd = "cp{0}{1}".format(deployment_file, deployment_dir).split() 
     --->return_code = subprocess.call(cmd, shell=False)<---- 
     else: 
      raise NameError("Deployment file not found [{0}]".format(deployment_file)) 

Im _copy_deployment_files Funktion haben versucht, das Verfahren Subprozess Herstellung Schalenparameter auf true

return_code = subprocess.call(cmd, shell=True) 

aber es enthält nicht die AlexaBaseHandler.py, AlexaDeploymentHandler.py und main.py.

Meine Frage ist, wie bekomme ich create_development, um AlexaBaseHandler.py, AlexaDeploymentHandler.py und main.py zum Bereitstellungspaket hinzuzufügen und wie stelle ich sicher, dass das Paket pygtfs auch im Bereitstellungspaket installiert ist? Hier

ist das Ergebnis, wenn return_code = subprocess.call (cmd, Shell = True)

    Create a zip archive from a directory.

    either no parent directory or just one parent directory, so it will trim any 
    leading directories in the filesystem paths and not include them inside the

    required argument. It can be absolute or relative, but only one or zero 
    leading directories will be included in the zip archive. 

    zipFilePath -- string path to the output zip file. This can be an absolute 
    or relative path. If the zip file already exists, it will be updated. If 
    not, it will be created. If you want to replace it from scratch, delete it 
    prior to calling this function. (default is computed as dirPath + ".zip")

UPDATE

NVM ich fand es heraus. Der Code, den ich kopiert habe, benutzte cp als Kopierbefehl für den Subprozess. Ich schaute den Befehl für mein Betriebssystem (Windows 10) nach und es war COPY nicht cp. Hier ist der neue Aufruf zum Subprozess

cmd = "COPY {0} 
    {1}".format(deployment_file,os.path.abspath(deployment_dir)).split()
