Error: cpan Out of memory! for update perl modules.

Posted on March 10, 2013 Updated on March 10, 2013

I’m getting an Out of memory! message for all installs. because cpan was not compiled  for unlimiter memory usage.

root@host01 [/home/]# cpan
cpan> install Build

Out of memory!
Lockfile removed.

I did a ulimit on the /.cpan directory and it resulted in unlimited. I used cpanm work with less memory.

root@host01 [~]# curl -L http://cpanmin.us | perl – –self-upgrade

You are running cpanm from the path where your current perl won't install executables to.
Because of that, cpanm --self-upgrade won't upgrade the version of cpanm you're running.

cpanm path : -
 Install path : /usr/bin

It means you either installed cpanm globally with system perl, or use distro packages such
as rpm or apt-get, and you have to use them again to upgrade cpanm.
