Problem Description

We want to release a plugin to spyder on conda-forge.
Our package must be a noarch type with the twist that python >= 3.8.
conda-forge insists and we run pip check in the recipe (which makes a lot of sense), however this fails because spyder relays on applaunchservices for OSX, but not all it's dependencies are in conda-forge ☹️ and thus the check fails as follows:

Fortunately for us, @goanpeca is the conda-forge reviewer, so I asked him if he could approve our feedstock when I do the following in or recipe:

This will get me up and running, however the cleaner way would be if we take the applaunchservices out of spyder's conda-forge recipe, this way others (like this guy from PROCITEC ?) will not have the same problem as us.

All plugins can then enable the normal pip check without selectors (and discussions with conda-forge) and once the applauchservices work again, then we can enable it again and support for spyder on OSX under CONDA, the plugin recipies don't have to do anything anymore (presumed that the plugins are noarch)

Could this be done in the upcomming 5.3.1 release already ?

Thanks for reporting @nerohmot! We'll take a look at this in our next release.

@impact27 is looking into this already. This is not a Spyder issue but an applaunchservices conda packaging issue, AFIK. See impact27/applaunchservices#1

We can fix this on our side by requiring a more recent version of applaunchservices.
