Remove Typing dependencie

I am implementing the service and when I try to execute the following message appears.

[ERROR] AttributeError: type object 'Callable' has no attribute '_abc_registry'
Traceback (most recent call last):

    self._abc_registry = extra._abc_registry

Manually delete the typing.py file, installed from the library dependencies, and do not generate the error.

Details
Python 3.7
cybersource-rest-client-python===0.0.20

Comienza con app.py y la importación de linksys/core/apigateway/response.py; después inspecciona el archivo typing.py mostrado en el traceback y la dependencia cybersource-rest-client-python===0.0.20. Reproduce el error de Python 3.7 y verifica que el ejemplo se ejecuta sin que esté instalado el archivo typing.py conflictivo.
