I ran into this error using Rakudobrew on appveyor (see after <snip>)
I'm new at using appveyor, so maybe my script is wrong. But I wonder whether its because of a name change to raku without a backward alias to perl6.
<snip> Rakudo has been built and installed. Updating shims Done, moar-2020.05.1 built rakudobrew build zef Cloning into 'zef'... Your branch is up to date with 'origin/master'. rakudobrew: perl6: command not found Command exited with code 1
