Installation fails due to conflicting python-dateutil version

[NeolithEra]

Hi, users are unable to run pygenealogicaltools due to dependency conflict with python-dateutil package. As shown in the following full dependency graph of pygenealogicaltools, mapbox requires _ python-dateutil >=2.5.0_，while botocore requires python-dateutil <2.8.1,>=2.1.

According to pip’s “first found wins” installation strategy, python-dateutil 2.8.1 is the actually installed version. However, python-dateutil 2.8.1 does not satisfy <2.8.1,>=2.1.

Suggested Solution

1. Ask your upstream project mapbox to fix his direct dependency to be python-dateutil <2.8.1,>=2.5.0. I have checked this revision will not affect your downstream projects now.
2. Ask your upstream project botocore to loose the version range of python-dateutil.

@Thimxx Which solution do you prefer, 1 or 2?
Please let me know your choice. I can submit a PR to solve this issue.

Interesting.... in fact, it should fail the installation of mapbox itself, isn't it? I have been able to install it.
Just noticed you have made the suggestion already. It looks mapbox is no longer maintained... I might need to change the library is no response.

Keep this link as tracking mapbox/mapbox-sdk-py#276

Which version of python are you using?
Just checked and ideally the low level botocore should be compatible with <3.0.0 dateutils

Version 2.8.1 of python-dateutil was created one month ago, likely this is the problem, dependencies look not to be updated.

Fixed in version 0.4.2, I introduced the dependencies, but in parallel I am trying to work to free the dependencies in the other packages... I would prefer to have more flexibility. So I keep the issue open until that is fixed.Now is accessible through pip

The mapbox development is paused. To be carefully looked as we might have an obsolescence of code.
