This is with KiPart 0.1.43 and I have tried python2 and python3.

mattvenn commented 3 years ago

I was still able to create the part by unzipping the zip file and making the symbol I wanted individually.

xesscorp commented 3 years ago

I wasn't able to recreate this problem on my machine running 0.1.43/Python 3.7/Ubuntu 20.04. Is there any other information on your environment that might be pertinent?

mattvenn commented 3 years ago

I'm on ubuntu 18.04. Python is python3.6

I can't think of anything else. Maybe the zipfile module for 3.6 doesn't allow seeking? Let me know if you want a specific test running.

xesscorp commented 3 years ago

Strangely enough, this seems to be a problem with Python 2.7, 3.5 and 3.6. It works OK on Python 3.7 and 3.8.

mattvenn commented 3 years ago

I confirm it works with python3.7 on my machine.
