perl模組安裝自訂路徑和使用

 

一 安裝perl模組到非自訂目錄

 

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_baseMakeMaker (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 /whatever2) Use PREFIX / --prefixModule::Build 0.28 added support for --prefix which works like MakeMaker's PREFIX.    perl Makefile.PL PREFIX=/whatever    perl Build.PL    --prefix /whatever

 

 

 

二 使用自訂目錄下的模組 

BEGIN {

    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 ~/perl5use local::lib '~/foo'; # same, but ~/foo

 

# Or...use FindBin;use local::lib "$FindBin::Bin/../support";  # app-local support libraryuse FindBin;use lib "$FindBin::Bin/../lib";

 

# oruse FindBin qw($Bin);use lib "$Bin/../lib";

 

三 尋找已經安裝的模組 

1. Shell 指令碼：find `perl -e ‘print “@INC”‘` -name ‘*.pm’ -print2. Perl 指令碼：#!/usr/bin/perluse strict;use ExtUtils::Installed;my $inst = ExtUtils::Installed->new();my @modules = $inst->modules();foreach (@modules) {my $ver = $inst->version($_) || “???”;printf( “%-12s — %s\n”, $_, $ver );}exit 0;

 

完！
