If you want to put the new module into a custom location that your cpan shell isn t configured to use  then perhaps  the following will be handy     wget  lt URL to the module tgz gt     unpack  perl Build PL   Build destdir  HOME install base  HOME   Build destdir  HOME install base  HOME install

A couple of people mentioned the cpan utility  but it s more than just starting a shell  Just give it the modules that you want to install and let it do it s work     prompt gt  cpan Foo  Bar   If you don t give it any arguments it starts the CPAN pm shell  This works on Unix  Mac  and should be just fine on Windows  especially Strawberry Perl    There are several other things that you can do with the cpan tool as well  Here s a summary of the current features  which might be newer than the one that comes with CPAN pm and perl    -a Creates the CPAN pm autobundle with CPAN  Shell- gt autobundle   -A module   module       Shows the primary maintainers for the specified modules  -C module   module       Show the Changes files for the specified modules  -D module   module       Show the module details  This prints one line for each out-of-date module  meaning  modules locally installed but have newer versions on CPAN   Each line has three columns  module name  local version  and CPAN version   -L author   author       List the modules by the specified authors   -h Prints a help message   -O Show the out-of-date modules   -r Recompiles dynamically loaded modules with CPAN  Shell- gt recompile   -v Print the script version and CPAN pm version

Lots of recommendation for CPAN pm  which is great  but if you re using Perl 5 10 then you ve also got access to CPANPLUS pm which is like CPAN pm but better   And  of course  it s available on CPAN for people still using older versions of Perl  Why not try     cpan CPANPLUS

On Unix  usually you start cpan in your shell    cpan and type install Chocolate  Belgian or in short form  cpan Chocolate  Belgian On Windows   If you re using ActivePerl on Windows  the PPM  Perl Package Manager  has much of the same functionality as CPAN pm   Example    ppm ppm gt  search net-smtp ppm gt  install Net-SMTP-Multipart see How do I install Perl modules  in the CPAN FAQ Many distributions ship a lot of perl modules as packages   Debian Ubuntu  apt-cache search  perl   Arch Linux  pacman -Ss   perl-  Gentoo  category dev-perl  You should always prefer them as you benefit from automatic  security  updates and the ease of removal  This can be pretty tricky with the cpan tool itself  For Gentoo there s a nice tool called g-cpan which builds installs the module from CPAN and creates a Gentoo package  ebuild  for you

Use cpan command as cpan Modulename    cpan HTML  Parser   To install dependencies automatically follow the below    perl -MCPAN -e shell cpan 1  gt   o conf prerequisites policy follow cpan 2  gt   o conf commit exit   I prefer App  cpanminus  it installs dependencies automatically  Just do    cpanm HTML  Parser

I note some folks suggesting one run cpan under sudo  That used to be necessary to install into the system directory  but modern versions of the CPAN shell allow you to configure it to use sudo just for installing  This is much safer  since it means that tests don t run as root   If you have an old CPAN shell  simply install the new cpan   install CPAN   and when you reload the shell  it should prompt you to configure these new directives   Nowadays  when I m on a system with an old CPAN  the first thing I do is update the shell and set it up to do this so I can do most of my cpan work as a normal user   Also  I d strongly suggest that Windows users investigate strawberry Perl  This is a version of Perl that comes packaged with a pre-configured CPAN shell as well as a compiler  It also includes some hard-to-compile Perl modules with their external C library dependencies  notably XML  Parser  This means that you can do the same thing as every other Perl user when it comes to installing modules  and things tend to  just work  a lot more often

A couple of people mentioned the cpan utility  but it s more than just starting a shell  Just give it the modules that you want to install and let it do it s work     prompt gt  cpan Foo  Bar   If you don t give it any arguments it starts the CPAN pm shell  This works on Unix  Mac  and should be just fine on Windows  especially Strawberry Perl    There are several other things that you can do with the cpan tool as well  Here s a summary of the current features  which might be newer than the one that comes with CPAN pm and perl    -a Creates the CPAN pm autobundle with CPAN  Shell- gt autobundle   -A module   module       Shows the primary maintainers for the specified modules  -C module   module       Show the Changes files for the specified modules  -D module   module       Show the module details  This prints one line for each out-of-date module  meaning  modules locally installed but have newer versions on CPAN   Each line has three columns  module name  local version  and CPAN version   -L author   author       List the modules by the specified authors   -h Prints a help message   -O Show the out-of-date modules   -r Recompiles dynamically loaded modules with CPAN  Shell- gt recompile   -v Print the script version and CPAN pm version

Simply executing cpan Foo  Bar on shell would serve the purpose

Lots of recommendation for CPAN pm  which is great  but if you re using Perl 5 10 then you ve also got access to CPANPLUS pm which is like CPAN pm but better   And  of course  it s available on CPAN for people still using older versions of Perl  Why not try     cpan CPANPLUS

On Fedora Linux or Enterprise Linux  yum also tracks perl library dependencies  So  if the perl module is available  and some rpm package exports that dependency  it will install the right package for you   yum install  perl Chocolate  Belgian      most likely perl-Chocolate-Belgian package  or even ChocolateFactory package

On ubuntu most perl modules are already packaged  so installing is much faster than most other systems which have to compile   To install Foo  Bar at a commmand prompt for example usually you just do   sudo apt-get install libfoo-bar-perl   Sadly not all modules follow that naming convention

User · Answer

On Fedora you can use    yum install foo   as long as Fedora has an existing package for the module
