Hello
I have installed Pycontact with the mentioned installation commands but I got the following error and I have Python 3 installed in my laptop also I can not find the zip file (pycontact-develop). I would be so thankful If you could help me.

edit: following the fix here (#81) worked wonderfully. If you're looking for the development zip, go here: https://github.com/maxscheurer/pycontact

and make sure the drop down menu on the left hand side of your screen says develop. That way when you download the zip from the code dropdown, it's the correct one.

Thanks @rjdespo for linking the related issue! I'm sorry the installation often causes this problem, which is due to the fact that I have not had the chance to thoroughly maintain this repo anymore..

Using the development zip doesn't fix the problem. I still receive the same error. Is there any other way around to fix this?
Thanks

If you get the exact same error, you're still using an older version of PyContact. The culprit file has been removed more than two years ago 😄 Probably your environment still has an old version around and the re-install didn't update that one? (Explained also in #81.)
