I could not reproduce this in a python3.9 docker container. What I did was:

$ docker run -ti python:3.9 bash
root@35f96f99f449:/# pip install linode-cli
root@35f96f99f449:/# linode-cli linodes list

This worked as expected, accepting a token and then listing my Linodes.

What command is giving you this error?

Could you also include the output of the following commands?

pip show colorclass
pip show linode-cli
python --version

It looks like there's a patch for the colorclass library that corrects this import, but I'm not completely sure why it's not working in python 3.9 for you, as the deprecation warning says this:

DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working

The actual commit that removes Mapping from collections is here, and is only tagged v3.10.0a6 and v3.10.0a5 - I don't believe this should be an issue in 3.9.x.

The upstream fix for colorclass is here: Robpol86/colorclass#27

If you can get me more info on your environment, I'll see if I can reproduce it and figure out what the issue is for 3.9. Otherwise, if the maintainers of that library won't fix it (and since the repo is archived, that seems unlikely), I might have to transition to a new library or fork that one.

I was able to reproduce this with python 3.9.0a1:

root@8807f71bd9b2:/# linode-cli linodes list

According to the release page, this was an "early developer preview" of python 3.9 from Nov 2019, with the official 3.9.0 being released in Oct 2020. It looks like this is a bug in the alpha release, and that this feature is not supposed to be removed until 3.10.0.

That said, since the library that is causing this issue appears to be unmaintained, I'm going to leave this issue open and work on replacing it before 3.10.0 comes out in Oct 2021.

OK thank you very much

FYI for anyone interested...
I have not had any issues with linode-cli and python 3.9.4.
As previously mentioned, probably something related to an alpha release.

python3 --version
Python 3.9.4

pip3 show linode-cli
