PyPI does not allow direct references in package deps (this is new)

[oberstet]

the usual python dependencies hassles .. needs some adjusts. in a fresh cpy 3.9 venv:

pip install -U -r requirements-dev.txt =>

• tox has deprecated (without fallback) whitelist_externals for allowlist_externals - the world has waited for that!
• tox doesn't allow / require to specifiy "." anymore:

I am tired of the brokeness of python deps mgmt - anyways:

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

alright, down to one confluent/conflicting deps:

• parsimonious
• eth-abi

 ERROR: Cannot install autobahn, crossbar==23.1.1.dev1 and eth-abi==2.2.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    crossbar 23.1.1.dev1 depends on parsimonious>=0.10.0
ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

    crossbar 23.1.1.dev1 depends on parsimonious>=0.10.0
    eth-abi 2.1.1 depends on parsimonious<0.9.0 and >=0.8.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Error: Process completed with exit code 1.
