Re: Package VERSIONs not parseable by the cpan module

Have you tried

o conf show_unparsable_versions
[download]

and rerunning the r command?

On my machine, there are 526 such modules. Most of them seem to be helper (sub)modules in distributions, not installable without the main module, e.g.

Module  < Test::Deep::Methods    (RJBS/Test-Deep-1.205.tar.gz)
Module  = App::Ack::Filter::Collection (PETDANCE/ack-v3.9.0.tar.gz)
Module  = Plack::Handler::HTTP::Server::PSGI (MIYAGAWA/Plack-1.0051.ta
+r.gz)
[download]

while some others are really weird, e.g.

Module  = overload::numbers      (BOOK/perl-5.42.0.tar.gz)
[download]

(I'm running this in 5.26.1 and I don't have 5.42.0 installed: I use 5.43.0 instead when experimenting with the new stuff). Update: The message probably shows the latest version at CPAN, which is 5.42.0. The module itself doesn't define a version:

$ perl -Moverload::numbers\ 999 -e1
overload::numbers does not define $overload::numbers::VERSION--version
+ check failed.
BEGIN failed--compilation aborted.
[download]

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

I have always simply used: $ perl -Moverload::numbers -e 'print $overload::numbers::VERSION' I like your method better, not least because it's shorter to type. And, as far as the configuration setting `show_unparsable_versions`, I did set that before using the r command the second time. Without that setting, cpan just ignores unversioned modules with the message: NNN installed modules have no parsable version number (where "NNN" varies by installation).
