Cannot build PyCall: InvalidVersionSpec: Invalid version '>=': invalid operator

Hi I am trying to use PyCall on the micromamba-docker image. Everything was working fine until a couple of days ago ( I realise PyCall wasn't updated a couple of days ago but this issue just started appearing).

Whenever I am trying to install one of our packages: RMS, it builds Conda fine but then gets to PyCall and produces this error:

#15 29.18 ERROR: LoadError: Error building `PyCall`:

Now I am not sure what the issue is but I did install mamba in the base environment for micromamba (mamba = 1.4.2). I have also tried to point ENV["CONDA_JL_CONDA_EXE"] to /usr/bin/micromamba but then I get another error from libmamba saying it cannot find the configuration file condarc-jl.yml. Uncertain what that file is.

If this is the wrong repo to ask this issue, please let me know!

JuliaPy / PyCall.jl
