Debugging a failed solve

When trying to install a large metapackage:


mamba install -c stanwell/uat -c https://conda.anaconda.org/fastai quantdev

mamba fails to solve and spits out the below message:


Looking for: ['quantdev']

Encountered problems while solving.
Problem: nothing provides vc 10.* needed by python-3.4.5-0

The is obviously because of inconsistent dependencies but the only python specification in the metapackage is for version 3.7 so I've no idea what package wants to use python-3.4.5-0

IIUC I can't use repoquery as it queries currently installed packages rather than the dependencies of a yet-to-be-installed package.

Is there any way I can get more info to debug this?

    I think what I want is depends --tree! :rocket:

    Unfortunately the output on my Windows box (powershell/cmd) is a bit garbled:

    Is the output correct for others on Windows? i.e. is it just my environment which is uniquely broken?
