Why does my CGI script complain "Can't locate CGI/Session.pm in @INC"? [duplicate]

Problem resolved after installing CGI-Session-4.42.

Thanks to all of you, for your help.

You need to install CGI::Session. Best way is to use your OS package manager. In Fedora/Redhat or similar it would be yum install perl-CGI-Session. In Debian-based, apt-get install libcgi-session-perl. If you want to install with cpan shell, paste somewhere whole log with errors and publish link to it here.
