Subject: cpan -g Module::Name not working at first (CPAN version is 2.05)
Download (untitled) / with headers
text/plain 2.9k
I have a perl 5.20.1 created with perlbrew running on OSX I tried to use cpan -g Module::Name and got some strange behavior. I have not used the cpan client in this perl earlier so before I tried cpan -g I ran 'cpan', let it autoconfigure and exited the shell. Without letting in download the index files first. I think this was the root of the problem as after it downloaded the index files, the command "cpan -g WWW::Mechanize" worked. Anyway, here is my interaction: $ cpan -g WWW::Mechanize Use of uninitialized value $description in concatenation (.) or string at /Users/gabor/perl5/perlbrew/perls/perl-5.20.1_WITH_THREADS/lib/5.20.1/App/Cpan.pm line 441. -- ignoring other arguments Checking WWW::Mechanize CPAN: Storable loaded ok (v2.51) Bizarre copy of ARRAY in list assignment at /Users/gabor/perl5/perlbrew/perls/perl-5.20.1_WITH_THREADS/lib/5.20.1/Carp.pm line 228. air:Downloads gabor$ air:Downloads gabor$ air:Downloads gabor$ cpanm CPAN --> Working on CPAN Fetching http://www.cpan.org/authors/id/A/AN/ANDK/CPAN-2.10.tar.gz ...

I couldn't reproduce this on my system, but I do notice the odd output of ignoring arguments. That's an unrelated issue, I think, but I'm working on that right now. Some of the features in cpan(1) probably assume a configured CPAN.pm. Maybe I'll have to trace the paths through the program to see which features might not give CPAN.pm a chance to do that.
