在Fedora/RHEL/CentOS中，perl 的library默认安装路径为：

@INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .)?

如果要使用自定义的perllib，就需要参考以下的设置了。

EDIT: Putting the right solution first,originally from?this question. It's the only one that searches relative to the?module?directory:

use FindBin; ? ? ? ? ? ? ? ? # locate this script
use lib "$FindBin::Bin/.."; ?# use the parent directory
use yourlib;

There's many other ways that search for libraries relative to the?current?directory. You can invoke perl with the -I argument,passing the directory of the other module:

perl -I.. yourscript.pl

You can include a line near the top of your perl script:

use lib '..';

You can modify the environment variable PERL5LIB before you run the?script:

export PERL5LIB=$PERL5LIB:..

The push(@INC) strategy can also work,but it has to be wrapped in BEGIN{} to make sure that the push is run before the module search:

BEGIN {push @INC, '..'}
use yourlib;
