Install issues with httpx

[iconoclasthero]

I had an issue installing audible and audible-cli on my ubuntu 20.04 machine with an error message about the version of httpx required so I pip install httpx==0.91.0 then I get an error on both of them that says...

Requirement already satisfied: idna; extra == "idna2008" in /usr/lib/python3/dist-packages (from rfc3986[idna2008]<2,>=1.3->httpx==0.19.0) (2.8) ERROR: audible 0.5.5 has requirement httpx==0.18.*, but you'll have httpx 0.19.0 which is incompatible. ERROR: audible-cli 0.0.dev19 has requirement httpx==0.16.*, but you'll have httpx 0.19.0 which is incompatible. Installing collected packages: httpcore, httpx Attempting uninstall: httpcore Found existing installation: httpcore 0.12.3 Uninstalling httpcore-0.12.3:

How can I have a newer version of httpx than both required but it doesn't install AND they need to have two different versions of the same pip package?

I think they actually installed, but...
