Discipulus has asked for the wisdom of the Perl Monks concerning the following question:

Hello monks and nuns,

before submitting a bug to the wonderful people who maintain strawberry perl I ask here just in case i missed something obvious..

The fact hitting me is that I cant get cpan client to report correctly modules versions installed.

about cpanminus option

I know cpan is not the only client to access CPAN and cpanm is the preferred solution for many of us, but it seems it has some issues (even if distributed along the portable edition!) because of paths expressed à la unix and some other strangness like cpanm --self-upgrade failing.

the problem with cpan client

Working with freshly downloaded and unzipped strawberry version and launching the portableshell.bat that come with each strawberry portable edition, and working, for example, with SDL module I have the following: 

----------------------------------------------
 Welcome to Strawberry Perl Portable Edition!
 * URL - http://www.strawberryperl.com/
 * see README.TXT for more info
----------------------------------------------
Perl executable: C:\right\path\strawberry-perl-5.26.0.2-64bit-portable
+BIS\perl\bin\perl.exe
Perl version   : 5.26.0 / MSWin32-x64-multi-thread


cpan> r SDL

..

All modules are up to date for SDL

[download]

But with the non interactive call (I suppose it's the same program anyway):

cpan -D SDL 

SDL
----------------------------------------------------------------------
+---
        (no description)
        F/FR/FROGGS/SDL-2.546.tar.gz
        (no installation file)
        Installed: not installed
        CPAN:      2.546  Not up to date
        Tobias Leich (FROGGS)
        froggs@cpan.org

[download]

All configuarations ( reviewed with o conf ) relative to working dirs ( build_dir cpan_home histfile keep_source_where make make_install_make_command patch prefs_dir ) are correct; absolute paths pointing to the current running version. Also @INC is correct for every portable distribution with strawberry prepended to it. The same for the PATH environment variable.

This happens with versions: strawberry-perl-5.26.1.1-32bit-portable  strawberry-perl-5.26.0.2-64bit-portable strawberry-perl-5.24.2.1-64bit-portable strawberry-perl-5.22.3.1-64bit-portable strawberry-perl-5.20.3.3-64bit-portable

Also happens: 

cpan> r Not_Existing_Module

..

All modules are up to date for Not_Existing_Module

[download]

What can I do? I missing something very simple? Thanks for the attention.

    Hi Lorenzo,

    I see the same with 5.24.0 32bit, however, I think SDL is not installed. At least I don't find it in the Release Notes.
    After installing it, cpan -D SDL reports "up to date".

    Update: The problem seems to be cpan reporting "up to date" for any not installed module:
    cpan> r Nonexisting::Module
All modules are up to date for Nonexisting::Module

    [download]
    This is not restricted to Strawberry, just confirmed it on my hoster's Linux (System Perl, 5.20.something)

    Update 2: What you want is probably cpan's i or m command:

    cpan> m SDL
Module id = SDL
    CPAN_USERID  FROGGS (Tobias Leich <froggs@cpan.org>)
    CPAN_VERSION 2.546
    CPAN_FILE    F/FR/FROGGS/SDL-2.546.tar.gz
    UPLOAD_DATE  2015-04-27
    INST_FILE    (not installed)

    [download]
    (before installing it) versus (afterwards)
    Module id = SDL
    CPAN_USERID  FROGGS (Tobias Leich <froggs@cpan.org>)
    CPAN_VERSION 2.546
    CPAN_FILE    F/FR/FROGGS/SDL-2.546.tar.gz
    UPLOAD_DATE  2015-04-27
    INST_FILE    C:\Install\perl-5.24.0.1\perl\site\lib\SDL.pm
    INST_VERSION 2.546

      Thanks soonix,

      I confirm that >cpan m SDL and the corrispective  CPAN::Shell->m('SDL') and also i works as expected.

      So the bug, if there is one as seems, is in the r command of cpan client and not a strawberry only issue.
