I am Perl beginner. I wanted to use Log::Log4perl module as I am familiar how it works in Java. I used cpanm script to download module, but I ran it without "sudo". Then it installed this module to my dir /home/amer/perl5. Afterwards, I installed it as sudoer, but I want to remove installation in my home dir to avoid any conflicts in future. How can I do that? Here is my cmdline execution stack.
Thanks and Regards!
That's quite experimental for the moment being, but now cpanm supports an uninstall option. From MetaCpan :
-U, --uninstall
EXPERIMENTAL: Uninstalls the modules. Will remove the distribution files from your library path using the .packlist file. When used with -l or -L, only the files under the local::lib directory will be removed. NOTE: If you have the "dual-life" module in multiple locations (i.e. site_perl and perl library path, with perl 5.12 or later), only the files in site_perl will be deleted. If the distribution has bin scripts and man, they will be kept in case the core installation still references that, although there's no guarantee that the script will continue working as expected with the older version of .pm files.
Try App::pmuninstall
DESCRIPTION
App::pmuninstall is a fast module uninstaller. delete files from .packlist.
App::cpanminus and, App::cpanoutdated with a high affinity.
From your user account go to shell/command prompt, enter PPM. When PPM opens type "remove [package name]" this will uninstall that particular package for you. type "help remove" in PPM for more details.
I have tried App::pmuninstall and it is worked for me fine.
Install module using command:
$ perl -MCPAN -e shell
Terminal does not support AddHistory. cpan shell -- CPAN exploration and modules installation (v1.9800) Enter 'h' for help. cpan[1]>install App::pmuninstall ... cpan[2]>quit
Usage.
On my local machine it has installed to /home/taras/perl5/bin/pm-uninstall
pm-uninstall [options] Module ...
options:
-v,--verbose Turns on chatty output -f,--force Uninstalls without prompts -c,--checkdeps Check dependencies (defaults to on) -n,--no-checkdeps Don't check dependencies -q,--quiet Suppress some messages -h,--help This help message -V,--version Show version -l,--local-lib Additional module path -L,--local-lib-contained Additional module path (don't include non-core modules)

I used David Farrell's script:
#!/usr/bin/perl # uninstall_perl_module.pl from PerlTricks.com use 5.14.2; use ExtUtils::Installed; use ExtUtils::Packlist; # Exit unless a module name was passed die ("Error: no Module::Name passed as an argument. E.G.\n\t perl $0 Module::Name\n") unless $#ARGV == 0; my $module = shift @ARGV; my $installed_modules = ExtUtils::Installed->new; # iterate through and try to delete every file associated with the module foreach my $file ($installed_modules->files($module)) { print "removing $file\n"; unlink $file or warn "could not remove $file: $!\n"; } # delete the module packfile my $packfile = $installed_modules->packlist($module)->packlist_file; print "removing $packfile\n"; unlink $packfile or warn "could not remove $packfile: $!\n"; # delete the module directories if they are empty foreach my $dir (sort($installed_modules->directory_tree($module))) { print("removing $dir\n"); rmdir $dir or warn "could not remove $dir: $!\n"; } It did the job although it produced some scary looking output :-):
