Command `zef install ...` results in `Type check failed for return value; expected IO::Path but got Any (Any)`

Context

I've used Zef in the distant past to install Perl6/Raku modules. When I try to do it recently, it always results in "Type check failed for return value; expected IO::Path but got Any (Any)", sometimes accompanied by other messages. But the quoted message is common to every run and is sometimes the only message.

Expected Behavior

Zef should install the module I ask it to.

Actual Behavior

I also tried running zef install .. This gives only the message above, even when running with --verbose and --debug flags: (base) mgipson-ltmx7ad:my_naive_dir mgipson$ zef --verbose --debug install . Type check failed for return value; expected IO::Path but got Any (Any)
