deno compile -A npm:cowsay not working

Hello, I am trying

deno compile -A npm:cowsay

deno compile -A npm:cowsay

and then following that with

./cowsay Hello World!

./cowsay Hello World!

but the result is:

error: Failed caching npm package 'cowsay@1.5.0'.

Caused by:
    An npm specifier not found in cache: "cowsay", --cached-only is specified.

error: Failed caching npm package 'cowsay@1.5.0'.

Is there something I'm missing? I'm currently on macOS. Deno version 1.36.4
