perlbrew is a program to automate the building and installation of perl in an easy way. It provides multiple isolated perl environments, and a mechanism for you to switch between them.
Everything are installed unter
~/perl5/perlbrew. You then need to include a bashrc/cshrc provided by perlbrew to tweak the PATH for you. You then can benefit from not having to run
sudocommands to install cpan modules because those are installed inside your
For the documentation of perlbrew usage see perlbrew command on MetaCPAN, or by running
perlbrew help, or by visiting perlbrew's official website. The following documentation features the API of
App::perlbrewmodule, and may not be remotely close to what your want to read.
It is the simplest to use the perlbrew installer, just paste this statement to your terminal:
curl -L https://install.perlbrew.pl | bash
Or this one, if you have
fetch(default on FreeBSD):
fetch -o- https://install.perlbrew.pl | sh
perlbrewinstalls itself to
~/perl5/perlbrew/bin, and you should follow the instruction on screen to modify your shell rc file to put it in your PATH.
The installed perlbrew command is a standalone executable that can be run with system perl. The minimum required version of system perl is 5.8.0, which should be good enough for most of the OSes these days.
A fat-packed version of patchperl is also installed to
~/perl5/perlbrew/bin, which is required to build old perls.
~/perl5/perlbrewwill contain all install perl executables, libraries, documentations, lib, site_libs. In the documentation, that directory is referred as
perlbrew root. If you need to set it to somewhere else because, say, your
HOMEhas limited quota, you can do that by setting
PERLBREW_ROOTenvironment variable before running the installer:
export PERLBREW_ROOT=/opt/perl5 curl -L https://install.perlbrew.pl | bash
As a result, different users on the same machine can all share the same perlbrew root directory (although only original user that made the installation would have the permission to perform perl installations.)
You may also install perlbrew from CPAN:
In this case, the perlbrew command is installed as
/usr/local/bin/perlbrewor others, depending on the location of your system perl installation.
Please make sure not to run this with one of the perls brewed with perlbrew. It's the best to turn perlbrew off before you run that, if you're upgrading.
perlbrew off cpan App::perlbrew
You should always use system cpan (like /usr/bin/cpan) to install
App::perlbrewbecause it will be installed under a system PATH like
/usr/bin, which is not affected by perlbrew
self-upgradecommand will not upgrade the perlbrew installed by cpan command, but it is also easy to upgrade perlbrew by running
perlbrew project uses github https://github.com/gugod/App-perlbrew/issues for issue tracking. Issues sent to these two systems will eventually be reviewed and handled. To participate, you need a github account.
