Module/Build.pm can not be located for perl - perl

Question

I am not a perl expert (see this page), but for using a package, I have to run some perl commands. The command shows this error
$ perl Build.PL
Can't locate Module/Build.pm in #INC (#INC contains: /home/mahmood/src/bioperl-1.6.1 /home/mahmood/src/ensembl/modules
/home/mahmood/src/ensembl-compara/modules /home/mahmood/src/ensembl-variation/modules
/home/mahmood/src/ensembl-funcgen/modules /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at Build.PL line 20.
BEGIN failed--compilation aborted at Build.PL line 20.
I see this reply which offers running cpan Module::Build first to fix that error. As I run that command, I see a bunch of questions (text wizard) which asks me a mirror url. Then it interactively asks my permission to install the packages. It seems that default answers to the questions has such effect. I also, didn't find which question is responsible for that. Please see the full output at pastebin.
Is there any way to automatically install the module, so that I can put that in a script for future things.
UPDATE:
It seems that I have to enter the cpan.org url however in my previous attempt, I used mirror websites. I tried the three commands proposed in the reply, but still get the same error:
Please enter the URL of your CPAN mirror http://www.cpan.org

Please remember to call 'o conf commit' to make the config permanent!

Answer 1

If you want to install Module::Build into your system libraries, then it's probably far easier to use the pre-built package that is almost certainly available for your system.
If you're using a RedHat-like Linux distribution, try:
$ sudo yum install perl-Module-Build
(Try dnf instead of yum on newer versions of Fedora.)
If you're using a Debian-like Linux distribution, try:
$ sudo apt-get install libmodule-build-perl

Answer 2

Now that you've got cpan configured, you can change the configuration to bypass asking you to install each dependency.
On the command line (note the o characters are literal... they are not points):
cpan
o conf build_requires_install_policy yes
o conf prerequisites_policy follow
o conf commit
To see a description of each item before entering your response manually:
cpan
o conf init build_requires_install_policy
When a module declares another one as a 'build_requires' prerequisite
this means that the other module is only needed for building or
testing the module but need not be installed permanently. In this case
you may wish to install that other module nonetheless or just keep it
in the 'build_dir' directory to have it available only temporarily.
Installing saves time on future installations but makes the perl
installation bigger.
You can choose if you want to always install (yes), never install (no)
or be always asked. In the latter case you can set the default answer
for the question to yes (ask/yes) or no (ask/no).
<build_requires_install_policy>
Policy on installing 'build_requires' modules (yes, no, ask/yes,
ask/no)? [yes]
o conf init prerequisites_policy
The CPAN module can detect when a module which you are trying to build
depends on prerequisites. If this happens, it can build the
prerequisites for you automatically ('follow'), ask you for
confirmation ('ask'), or just ignore them ('ignore'). Choosing
'follow' also sets PERL_AUTOINSTALL and PERL_EXTUTILS_AUTOINSTALL for
"--defaultdeps" if not already set.
Please set your policy to one of the three values.
<prerequisites_policy>
Policy on building prerequisites (follow, ask or ignore)? [follow]
After you've set them, don't forget to do a:
o conf commit
...to save your changes.
Now run:
cpan Module::Build
...and finally, run your build script:
./Build.PL
