perl模块安装自定义路径和使用

How do I get MakeMaker and Module::Build to install to the same place?

Module::Build,as of 0.28,supports two ways to install to the same location as MakeMaker.

1) Use INSTALL_BASE / --install_base

MakeMaker (as of 6.31) and Module::Build (as of 0.28) both can install to the same locations using the "install_base" concept. See "INSTALL_BASE" in ExtUtils::MakeMaker for details. To get MM and MB to install to the same location simply set INSTALL_BASE in MM and --install_base in MB to the same location.

? ? perl Makefile.PL INSTALL_BASE=/whatever

? ? perl Build.PL ? ?--install_base /whatever

2) Use PREFIX / --prefix

Module::Build 0.28 added support for --prefix which works like MakeMaker's PREFIX.

? ? perl Makefile.PL PREFIX=/whatever

? ? perl Build.PL ? ?--prefix /whatever

? ? push (@INC,'/opt/perl/lib');

}

BEGIN {

? ? unshift @INC,'/opt/perl/lib';

}

use lib '/opt/perl/lib';

use local::lib; # sets up a local lib at ~/perl5

use local::lib '~/foo'; # same,but ~/foo

# Or...

use FindBin;

use local::lib "$FindBin::Bin/../support"; ?# app-local support library

use FindBin;

use lib "$FindBin::Bin/../lib";

# or

use FindBin qw($Bin);

use lib "$Bin/../lib";

1. Shell 脚本：

find `perl -e ‘print “@INC”‘` -name ‘*.pm’ -print

2. Perl 脚本：

#!/usr/bin/perl

use strict;

use ExtUtils::Installed;

my $inst = ExtUtils::Installed->new();

my @modules = $inst->modules();

foreach (@modules) {

my $ver = $inst->version($_) || “???”;

printf( “%-12s — %sn”,$_,$ver );

}

exit 0;

完！
