Unable to import from smpp.twisted.client

[sbilly-qmedic]

Hello,

For some reason, I can't get past the third line (import from smpp.twisted.client). Here is the stacktrace:

Traceback (most recent call last):
  File "test.py", line 3, in <module>
    from smpp.twisted.client import SMPPClientTransceiver, SMPPClientService
  File "/usr/local/lib/python2.7/site-packages/smpp/twisted/client.py", line 21, in <module>

  File "/usr/local/lib/python2.7/site-packages/smpp/pdu/pdu_types.py", line 20, in <module>
    CommandId = Enum(*constants.command_id_name_map.keys())
TypeError: __call__() takes at most 6 arguments (28 given)

I think the issue may come from the enum module? I have pyOpenSSL (v0.13), enum (v0.4.6), Twisted (v16.6.0), smpp.pdu (v0.3), and smpp.twisted (v0.4) installed.

Not sure why it would fail, though?

Are you using virtual environment ?

[sbilly-qmedic]

Yes, actually - I tried to set it up on an Amazon EC2 instance. Is this a known issue with the Enum module and virtual environments, by any chance?

[gagandce]

I am having the same issue. Is there a fix for this ? Actually I am surprised that using virtual environment will break Enum ???

[davidjmorris]

I have the same issue using python 2.7.12 I think this happens because smpp.twisted required enum PyOpenSSL requires enum34 and this clashes with enum smpp.twisted requires PyOpenSSL so then we have a clash between enum and enum34

I tried to remove enum34 and leave enum alone. Getting the following error

I'm getting the same error. Removed enum34 with no success. Has anyone been past this point?
