SymPy's CI that runs asv is breaking (see sympy/sympy#25561) with this error:

Run asv run --config asv.conf.actions.json
Couldn't load asv.plugins.mamba because
No module named 'mamba'
Couldn't load asv.plugins.virtualenv because
No module named 'packaging'
· Unknown environment type 'virtualenv'
· No environments selected
Error: Process completed with exit code 1.

I've looked through the change log and the diff of 0.6.0 to the last release and see that there is a new mamba plugin, but I haven't been able to see why these failures are occurring or if we are supposed to update something on our end to work with the new release. Can you provide a suggestion?
