Package command should be more verbose when errors are encountered

I've been using the 'quickly package' command several times in my app, and today for some reason it failed.

However, I cannot really tell what failed or how I could fix it, as the output of the command only tells me "package command failed" (see output below).

It would be extremely useful that the command told me the cause of the failure

$ quickly package
