Issue

The linter passes in CI on conda-forge/scipy-stubs-feedstock#10, but locally I see

[lucascolley]

the error here is resolved by passing recipe_directory or running the command from the directory of the recipe.

So the correct fix here is to improve the error message - it can happen if there is no recipe/meta.yaml, but also if there is no recipe.yaml in the cwd when the command is run.
