Describe your issue

conda-smithy has an environment.yml file which specifies the dependencies necessary for the development of smithy.

Recent changes (conda-forge/conda-smithy@86ffbd9 & conda-forge/conda-smithy@814ffed) added new dependencies to that file, but when I do

mamba update --file environment.yml

to update my existing environment (that had been created in the past), after updating my local checkout to upstream main (conda-forge/conda-smithy@814ffed), those new dependencies (py-rattler, etc.) end up not getting installed.

There is no error in the logs, so the fact that the installation of mamba update --file environment.yml succeeds without matching the specification in that file is very misleading. After running this command, the environment needs to match the constraints in the file (ideally), or a clear error needs to be raised if that's not possible for some reason.
