also the error messaging when you can't satisfy a rule (in this case, i was trying to

yield Get(Snapshot, PathGlobsAndRoot, ...)

) made me waste several hours today because it just said "no installed rules could satisfy the selection" or something and i'm not sure where to change to make that better

Fun fact - you get exactly the same error message if there are ambiguous routes through the graph, or loops

ambiguous routes gets you a different error, but yea a loop would be the same one.

yeah i was thinking like how could this have been solved in general with like finding paths to things, but upon waking up i realized all i wanted was to note the specific e.g.

yield Get(...)

which caused the failure

Ambiguous routes got you the exact same error as of Thursday...

@average-vr-56795: a repro of that would be good... you should be getting https://github.com/pantsbuild/pants/blob/master/src/rust/engine/src/rule_graph.rs#L176-L193

thanks!
