perl模塊的安裝,查詢

linux下cpan安裝:# perl -MCPAN -e shell ? ? ? ? ? ? // 一路回車配置cpan,個別地方需要輸入cpan> install 模塊名
以后安裝就可以:
# perl -MCPAN -e 'install 模塊名'
windows下ActivePerl安裝:直接用Perl Packge Manager圖形安裝就可以了

查詢安裝好的模塊:當你需要使用模個模塊,不知道是不是安裝了的時候,可以使用下面的命令查看:# perldoc perllocal有類似下面的東西出來:PERLLOCAL(1) User Contributed Perl Documentation PERLLOCAL(1)

Thu Feb 18 11:24:54 2010: "Module" Digest::HMAC

· "installed into: /usr/lib/perl5/site_perl/5.8.8"

· "LINKTYPE: dynamic"

· "VERSION: 1.02"

· "EXE_FILES: "

· "installed into: /usr/lib/perl5/site_perl/5.8.8"

· "LINKTYPE: dynamic"

· "VERSION: 2.56"

· "EXE_FILES: "



另外還可以使用下面的命令:# perl -MConfig::IniFiles -e 1如果不報錯就是已經安裝了.
shell下直接輸入下面命令,可以找到所有已經安裝的模塊.路徑# find `perl -e 'print "@INC"'` -name '*.pm' -print


或者用這個腳本: ?很詳細.http://cpansearch.perl.org/src/MLFISHER/pmtools-1.01/pminst#!/usr/bin/env perl
# pminst -- find modules whose names match this pattern

}????

$pattern = shift();

=head1 NAME

pminst - find modules whose names match this pattern

=head1 SYNOPSIS

pminst [B<-s>] [B<-l>] [I<pattern>]

=head1 DESCRIPTION

Without argumnets, show the names of all installed modules.????Given a
pattern, show all module names that match it.????The B<-l> flag will show
the full pathname.????The B<-s> flag will separate the base directory from
@INC from the module portion itself.


=head1 EXAMPLES

????????$ pminst
????????(lists all installed modules)

????????$ pminst Carp
????????CGI::Carp
????????Carp

????????$ pminst ^IO::
????????IO::Socket::INET
????????IO::Socket::UNIX
????????IO::Select
????????IO::Socket
????????IO::Poll
????????IO::Handle
????????IO::Pipe
????????IO::Seekable
????????IO::Dir
????????IO::File

????????$ pminst '(?i)io'

????????IO::Socket
????????IO::Poll
????????IO::Handle
????????IO::Pipe

????The -s flag provides output with the directory separated
????by a space:

????????$ pminst -s | sort +1
????????(lists all modules, sorted by name, but with where they????
???????? came from)

????????$ oldperl -S pminst -s IO
????????/usr/lib/perl5/i386-linux/5.00404 IO::File

最后一個腳本,是查找你安裝的所有第三方模塊及其版本號:#!/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;




windows下還是那個東西,圖形的.
