python3 unicode error

Hi, I’m running Windows 10 with a miniconda3 (python3) I installed gooey (v1.0.2) and pyinstaller (v3.4) today following the ‘packaging’ instructions here: https://chriskiehl.com/article/packaging-gooey-with-pyinstaller

I only changed this line to be added in my python script from this nonbuffered_stdout = os.fdopen(sys.stdout.fileno(), 'w', 0) to this nonbuffered_stdout = os.fdopen(sys.stdout.fileno(), 'w') because of python3 needs (see this stackoverflow topic ) But I’ve got the following error.

> pip install Gooey 
> pip install pyinstaller
> cd c:\mybuildingdir
> python test.py 
# this runs successfully
> pyinstaller build.spec

Any suggestion?

You. Are. Amazing!

I’ve long been bugging people to add their packaging experiences / knowledge to the wiki. You are the first! Thanks for the wiki contribution!

Uh I solved the ‘Fatal Error Detected: Failed to execute script’ error too! Thanks to this issue here https://github.com/chriskiehl/Gooey/issues/295 I changed the build.spec file line console=False, to console=True, and it works! I’ll add a step-by-step user guide to your wiki here: https://github.com/chriskiehl/Gooey/wiki/step-by-step-guide:-python3-gooey-and-pyinstaller I believe it could be useful to the community
