Perlbrew cannot run simple scripts IPC::System::Simple required for Fatalised/autodying system()

I am a new perlbrew user, as I wish to upgrade to perl 5.30.0 on Ubuntu.

I have done

perlbrew init
perlbrew install perl-5.30.0
perlbrew switch perl-5.30.0

so I try to run this test script:

#!/usr/bin/env perl

use strict;
use warnings FATAL => 'all';
use feature 'say';
use autodie ':all';

but this gives the long error 

IPC::System::Simple required for Fatalised/autodying system() at /home/con/Scripts/say.pl line 6.
    main::BEGIN() called at /home/con/Scripts/say.pl line 6
    eval {...} called at /home/con/Scripts/say.pl line 6
BEGIN failed--compilation aborted at /home/con/Scripts/say.pl line 6.
Command exited with non-zero status 2

I thought that libraries (especially standard ones) were supposed to be loaded automatically via perlbrew? How can I get this simple script to run?

Solution

  • The solution, according to @ikegami, and that worked for me: /home/con/perl5/perlbrew/perls/perl-5.30.0/bin/perl -e'use IPC::System::Simple'; /home/con/perl5/perlbrew/perls/perl-5.30.0/bin/cpan IPC::System::Simple; /home/con/perl5/perlbrew/perls/perl-5.30.0/bin/perl -e'use IPC::System::Simple'

    of course, for anyone in the future, this will be slightly different for you, as your directories may be set differently, and username isn't con
