Upgrading above 4.8.2 adds Ruamel.yaml to fresh environments and causes conflicts

[glassresistor]

The most recent update to the miniconda docker image is causing us to have this error with ruamel.yaml

I'm not sure where this got added to the base dependency tree but my experience with conda outside of this environment is that base install doesnt install ruamel.yaml.

We hit this as soon as your released so i suspect others will as well. Pinning to 4.8.2 fixed it but id like to upgrade eventually.

What are you trying to install? Knowing that will help make it easier to track down this issue.

[glassresistor]

I haven't tracked down which package it is but just trying to upgrade from the systems version of ruamel-yaml should cause the issue. So just running this should trigger the same issue.

pip install ruamel-yaml --upgrade

I think the solution is to just make sure ruamel-yaml is not preinstalled on a conda env on this docker image and that the envs more closely resemble vanilla ones.
