nonempty __slots__ not supported for subtype of 'str' TypeError: Error when calling the metaclass bases #70

Closed emezeta closed 2 years ago

Hi guys, I know it's a pain ... I already see #68 :( After a while of poking around on the net, I found out that this is a very old discussion. Since none of the tips I found have worked for me, I'm leaving the question here to see if anyone can throw me a line of help.

pip2 install suds Downloading/unpacking suds Downloading suds-1.0.0.tar.gz (283kB): 283kB downloaded

my code is silly simple and runs smoothly from a python 2.7.9 prompt:

from suds.client import Client
client = Client(ws_url)

res = client.service.remote_method(...)

The error comes when you call the function where this code live.

    from suds.sax.text import Text
  File "/usr/local/lib/python2.7/dist-packages/suds/sax/text.py", line 25, in <module>
    class Text(str):
TypeError: Error when calling the metaclass bases
    nonempty __slots__ not supported for subtype of 'str'

It is a legacy erp application that I cannot upgrade to py3. Thanks you guys in advance. Marcelo

Hi, I understood that it'll be healthier to split the approach into two different python versions. An external call - maybe subprocess - from the ERP.py2 to the script.py3 in which suds interacts with the WS. Sorry for the noise! I close this topic now.

👋 unfortunately this is due to the change in https://github.com/suds-community/suds/pull/58/ to move from subclassing unicode to subclassing str, which is part of natively supporting python 3.

Please note that suds-community v0.8.5 fully supports python 2.7, my recommendation would be to pin to that version.

is running fine with subprocess now, but naturally it will be easier and cleaner without such version mixing. Thanks a lot for the tip
