Failed to install CPAN Perl module(s) LWP::UserAgent

Today I stuck in this error when recompiling php using easyapache. It was giving error to fail to install the given perl module.

!! Failed to install CPAN Perl module(s) LWP::UserAgent !!

Failed to install CPAN Perl module(s) LWP::UserAgent

When i check it using cpan , It says that this module is already installed and up to date. 

I tried different solutions to check why it is not getting installed.

Some on them was using cpan

root@server [~]# cpancpan>cpan> install  LWP::UserAgent

CPAN: Storable loaded ok (v2.20)

Reading '/home/.cpan/Metadata'

  Database was generated on Thu, 13 Jun 2013 21:53:03 GMT

CPAN: Module::CoreList loaded ok (v2.18)

LWP::UserAgent is up to date (6.05).

I even tried opening a support ticket but could not process free cpanel ticket due to some error .

Solution:

Then i tried to uninstall the given perl module so i can re-install it. Inorder to un-install the perl module I downloaded cpanminus.

curl -L http://cpanmin.us | sudo perl - App::cpanminus
sudo cpanm LWP::UserAgent

Then I run the command to uninstall the perl module using

 cpanm -U LWP::UserAgent

and then installed the module again using

 root@server [~]# cpan
cpan>
cpan> install LWP::UserAgent

And then run easyapache again and it all went successfully.. So writing this so some one might get benefit of it.

function sumArraykey($array,$key){
 foreach($array as $first){
                $first[$key]="";
                $distinct[]=$first;
        }

        $unique = array_map("unserialize", array_unique(array_map("serialize", $distinct)));
        foreach($unique as $first){
                $sum=0;
                foreach($array as $second){
                        $val=$second[$key];
                        $second[$key]="";
                        $matchcounter=1;
                        if($second == $first){
                                $matchcounter++;
                                $sum+=$val;
                        }
                }

Example use!!!


$test[]=array(0=>1,1=>2,2=>3,3=>4,4=>5,5=>6,6=>10);
$test[]=array(0=>1,1=>2,2=>3,3=>4,4=>5,5=>6,6=>10);
$test[]=array(0=>1,1=>2,2=>3,3=>4,4=>5,5=>6,6=>10);
$test[]=array(0=>3,1=>2,2=>3,3=>4,4=>5,5=>6,6=>10);
$test[]=array(0=>3,1=>2,2=>3,3=>4,4=>5,5=>6,6=>10);

$output=sumArraykey($test,6);
print_r($output);
