rmgmolecule: supported python version

[oroppas]

Hi,

I installed RMS following https://github.com/ReactionMechanismGenerator/ReactionMechanismSimulator.jl/wiki/RMS-Installation#as-a-user but got the following rmgmolecule-related issue:

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - rmgmolecule -> python==3.7

Your python: python=3.10

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

Will rmgmolecule support python 3.10 or greater?

[mjohnson541]

So rmgmolecule is fundamentally a separately packaged subset of RMG-Py. At the moment RMG-Py doesn't support python > 3.7, although there are long term intentions to support newer python versions.

[mjohnson541]

You should still be able to install it though, but if you need python packages that need a newer python they won't be able to live in the same conda environment.
