pixi task list should warn if user is running on platform not in platforms #3441
Description
Problem description
Hi,
I was just testing out pixi for the first time using the tooling in array-api-extra. Since I was on an Intel Mac(osx-64), which had been omitted from the array-api-extra project.platforms mistakenly, I wasn't able to run any of the tasks, and got confusing warning messages when I tried to do so.
e.g.
I would get
thomasli@x86_64-apple-darwin13 array-api-extra % pixi task list
No tasks found
and for running a task called coverage
thomasli@x86_64-apple-darwin13 array-api-extra % pixi run coverage
Traceback (most recent call last):
File "/Users/thomasli/opt/miniconda3/envs/scikit-learn/bin/coverage", line 5, in <module>
from coverage.cmdline import main
ModuleNotFoundError: No module named 'coverage'
(From my understanding, when pixi can't find a task it just tries to execute an executable under bin. I don't think this is the correct behavior though, as it made me go down the rabbit hole try to install dependencies myself - which I shouldn't be doing, instead of checking the pixi config.)
It makes sense that tasks shouldn't be runnable on an unsupported platform, however, I would expect a better error message.
e.g.
Found task <xxx> that is only supported on platforms [a,b,c]. You are on platform <yyy>
(Thanks for pixi btw, it seems to work great other than this snag)
