44 perlbrew is a program to automate the building and installation of perl
45 in an easy way. It provides multiple isolated perl environments, and a
46 mechanism for you to switch between them.
47 Everything are installed unter "~/perl5/perlbrew". You then need to
49 include a bashrc/cshrc provided by perlbrew to tweak the PATH for you.
50 You then can benefit from not having to run "sudo" commands to install
51 cpan modules because those are installed inside your "HOME" too.
52 For the documentation of perlbrew usage see perlbrew command on
54 MetaCPAN <https://metacpan.org/>, or by running "perlbrew help", or by
55 visiting perlbrew's official website <https://perlbrew.pl/>. The
56 following documentation features the API of "App::perlbrew" module, and
57 may not be remotely close to what your want to read.

60 It is the simplest to use the perlbrew installer, just paste this
61 statement to your terminal:
62 curl -L https://install.perlbrew.pl | bash
64 Or this one, if you have "fetch" (default on FreeBSD):
66 fetch -o- https://install.perlbrew.pl | sh
68 After that, "perlbrew" installs itself to "~/perl5/perlbrew/bin", and
70 you should follow the instruction on screen to modify your shell rc
71 file to put it in your PATH.
72 The installed perlbrew command is a standalone executable that can be
74 run with system perl. The minimum required version of system perl is
75 5.8.0, which should be good enough for most of the OSes these days.
76 A fat-packed version of patchperl is also installed to
78 "~/perl5/perlbrew/bin", which is required to build old perls.
79 The directory "~/perl5/perlbrew" will contain all install perl
81 executables, libraries, documentations, lib, site_libs. In the
82 documentation, that directory is referred as "perlbrew root". If you
83 need to set it to somewhere else because, say, your "HOME" has limited
84 quota, you can do that by setting "PERLBREW_ROOT" environment variable
85 before running the installer:
86 export PERLBREW_ROOT=/opt/perl5
88 curl -L https://install.perlbrew.pl | bash
89 As a result, different users on the same machine can all share the same
91 perlbrew root directory (although only original user that made the
92 installation would have the permission to perform perl installations.)
93 You may also install perlbrew from CPAN:
95 cpan App::perlbrew
97 In this case, the perlbrew command is installed as "/usr/bin/perlbrew"
99 or "/usr/local/bin/perlbrew" or others, depending on the location of
100 your system perl installation.
101 Please make sure not to run this with one of the perls brewed with
103 perlbrew. It's the best to turn perlbrew off before you run that, if
104 you're upgrading.
105 perlbrew off
107 cpan App::perlbrew
108 You should always use system cpan (like /usr/bin/cpan) to install
110 "App::perlbrew" because it will be installed under a system PATH like
111 "/usr/bin", which is not affected by perlbrew "switch" or "use"
112 command.
113 The "self-upgrade" command will not upgrade the perlbrew installed by
115 cpan command, but it is also easy to upgrade perlbrew by running "cpan
116 App::perlbrew" again.
