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_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

 

 

 

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 ~/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";

 

三 尋找已經安裝的模組  1. Shell 指令碼： find `perl -e ‘print “@INC”‘` -name ‘*.pm’ -print 2. Perl 指令碼： #!/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 — %s\n”, $_, $ver ); } exit 0;

  完。
