Subject:

Undefined subroutine &CPANPLUS::Dist::MM::can_load

I get this error for EVERY module. cpanp has rendered useless by something. ... [MSG] Extracted 'Data::Table' to '/disk1/src/PERL/.cpanplus/5.9.2/build/Data-Table-1.47' [ERROR] Undefined subroutine &CPANPLUS::Dist::MM::can_load called at /usr/local/lib/perl5/site_perl/5.9.2/CPANPLUS/Dist/MM.pm line 139.

I quit cpanp and restarted and did exactly the same steps as last time but now it's working fine. If it happens again I'll resubmit. Sorry for the false alarm! -- - - Martin 'Kingpin' Thurn

OK This is happening consistently now. Before running the 'o' command, I can install modules. After running the 'o' command, ALL installation attempts fail with [ERROR] Undefined subroutine &CPANPLUS::Dist::MM::can_load called at /usr/local/lib/perl5/site_perl/5.9.2/CPANPLUS/Dist/MM.pm line 139. I can only imagine that during 'o', some module that I have installed has a "bad" $VERSION string that screws up cpanp when it evals it. Any suggestions on how to debug this? -- - - Martin 'Kingpin' Thurn

I've tried reproducing it on my system but failed, which makes me think indeed it's "a" module on your system that's throwing a bad version and perhaps breaking other things all together. The part where the check is done is in CPANPLUS::Shell::Default::_uptodate. You'll notice these lines: for my $mod (@list) { ### skip this mod if it's up to date ### next if $mod->is_uptodate; if you follow that with a: die Dumper($mod) unless CPANPLUS::Dist::MM->can('can_load'); you might find the culprit.. This is a nasty issue indeed... good luck debugging and feel free to ask if you have any more questions.

Cwd.pm is the module that apparently screws things up. Here's what it says about VERSION: % grep VERSION /opt/local/lib/perl5/5.9.2/sun4-solaris/Cwd.pm use vars qw(@ISA @EXPORT @EXPORT_OK $VERSION); $VERSION = '3.18'; XSLoader::load( __PACKAGE__, $VERSION ); __PACKAGE__->bootstrap( $VERSION ); $VERSION = eval $VERSION; -- - - Martin 'Kingpin' Thurn

Well done tracking it down... however, i've been unable to reproduce this error (testing specifically agianst Cwd version 3.18) using the commands you issued. So currently, i'm not sure what a 'fix' for your situation would be. If you have any suggestions or patches, i'm of course happy to take them. Good luck, Jos
