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 fromthis question. It's the only one that searches relative to themoduledirectory:
use FindBin; # locate this script
use lib "$FindBin::Bin/.."; # use the parent directory
use yourlib;
There's many other ways that search for libraries relative to thecurrentdirectory. You can invoke perl with the -I argument, passing the directory of the other module:
perl -I.. yourscript.pl
You can include a line near the top of your perl script:
use lib '..';
You can modify the environment variable PERL5LIB before you run thescript:
export PERL5LIB=$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;
