Question

Perl : Error during installion of a module of CPAN

Answer 1

A:

Can you post the output of:

cpan RDF::Trine

or even

cpan Bundle::CPAN

A LOT of perl developers develop on MacOS. I'd be surprised if it didn't work out of the box.

Updated, easier to read cpan output here than in a comment. It looks like your cpan is set to ignore dependencies:

---- Unsatisfied dependencies detected during ----

prerequisites_policy is the configuration variable that controls this behavior.

Confirm the setting by running o conf prerequisites_policy and if it's set to anything other than ask, run:

o conf prerequisites_policy ask
o conf commit

(Those are lowercase letter "oh")

Then repeat your cpan commands.

If I apply the sudo cpan Bundle::CPAN, Ive an error : Non-zero exit status: 2 Parse errors: Bad plan.

Downvote for teaching `sudo cpan`. This is not a good idea at all because the tests run with root privileges. Instead, they should be used only for installing into system locations. [`make_install_make_command` and `mbuild_install_build_command`](http://p3rl.org/CPAN#Config_Variables) exist for this reason.

@daxim - Sorry about that. I've been doing it like that for *years*. does the cpan command default to using sudo if it's available automatically?

Jason 2010-08-13 10:18:03

@user376112 -- you can post that output as a new answer, to your question, or edit your original question to include this output. It'd be easier to read in those cases than as a comment. However -- from the snip you did paste, it looks like you also need ExtUtils::MakeMaker. Try installing that via cpan, then retry your original list. cpan is *supposed* to be able to track this and do it for you, so something is not quite kosher here.

Jason 2010-08-13 10:24:36

Undid downvote after edit. No, CPAN does not default to using `sudo` if available. If you want this improvement, you can write up a patch: https://github.com/andk/cpanpm

My output is too long for stackoverflow. I've uploaded my output file at this URL : http://rapidshare.com/files/412708777/outuptRDF.txtIt's for the command : cpan RDF::Trinethanks for your help

2010-08-13 12:48:33

Thanks again for your answer. The problem is the same as I told before. My cpan shell is crashed. If I try to execute a command inside, I've an error. For example, If I apply your command, I've this : cpan[1]> o conf prerequisites_policy askArgument "yes" isn't numeric in numeric ge (>=) at /Library/Perl/5.8.8/Term/ReadLine/readline.pm line 2192Do you know the cause of this problem?

2010-08-13 13:58:00

Try manually editing /System/Library/Perl/5.8.8/CPAN/Config.pm (this is the path to the file on my MacOS 10.5 PPC machine)

Jason 2010-08-13 14:29:46

After you correct that problem, you may want to re-install Term::ReadLine ASAP to correct the readline problems.

Jason 2010-08-13 14:31:04

The path is correct. However, I've no such file in thedirectory /System/Library/Perl/5.8.8/CPAN. Do I have to create this file? If yes, could you show me the content of your file?Thanks

2010-08-13 14:54:09

could I see the content of your file?

2010-08-18 11:38:47

@user376112 - sorry, I vanished for a few days, and I didn't have my mac booted up (it's a slow G4 1ghz :-/) I've dumped my config @ http://pastebin.com/TZFqiph1 , it's good for the next month.
