Installing and configuring Perl using perlbrew on macOS or Linux

• Installing Perl using Perlbrew. It will be a Perl installation separate from macOS's system Perl (/usr/bin/perl).

    curl -L http://install.perlbrew.pl | bash
  
  

Put the appropriate initialization command into ~/.bashrc:

if <span class="createlink">bashrc </span>; then
    source ~/perl5/perlbrew/etc/bashrc
fi

Open a new terminal.

• Upgrade perlbrew

    perlbrew self-upgrade
  
  

• Install or upgrade perl

Replace with X.Y.Z with the latest stable version found on https://www.perl.org/get.html:

perlbrew install perl-X.Y.Z

Tell perlbrew which version of Perl to use:

perlbrew use X.Y.Z

Upgrade Perl:

perlbrew upgrade-perl

It can be a slow process, monitor the log:

tail -f ~/perl5/perlbrew/build.perl-X.Y.Z.log

• Verify perl installed correctly:

    perlbrew use X.Y.Z
    perl -V
  
  

Verify that $HOME/perl5/lib/perl5 is in @INC.

• Install cpanm

    perlbrew install-cpanm
  
  

• Install Perl modules using cpanm

Markdown::Foswiki, a Perl module for Markdown-to-TWiki conversion:

experimental module:
