Python error - AttributeError: 'module' object has no attribute 'UTC' about bittytax

[grumpydolphin]

I have tried the application with python3 as you suggested, and it's working without the errors. This is using the python distribution installed with homebrew

I was getting the error when using the default Catalina python (which I believe is 2.7).

Can you confirm which version of python you are using? python --version

Also, can you let me know which version of python-dateutil you have installed? pip show python-dateutil

You could try installing it with python3 instead? Using pip3 install BittyTax, it will ask you to install Xcode if you haven't already?

Managed to recreate the issue.

MacOS Catalina comes with python-dateutil v1.5 installed, this version does not contain the dateutil.tz.UTC constant.

It was introduced in v2.7.0 so will update the setup.py script to make this version or newer is used.
