Perl从cron.daily运行时找不到模块 [英] Perl can't find module when run from cron.daily
问题描述
我有perl程序使用Net :: Finger，并从Fedora 11中的cron.daily成功运行。
我刚刚将服务器升级到Fedora 18，这些相同的perl程序不再从cron运行但以root身份登录时从命令行运行良好。
错误是：
无法在@INC中找到Net / Finger.pm（@INC包含：/ usr / ）
（/ lib / perl5 / usr / local / share / perl5 / usr / lib64 / perl5 / vendor_perl / usr / share / perl5 / vendor_perl / usr / lib64 / perl5 / usr /模块的路径是/root/perl5/lib/perl5/Net/Finger.pm，但我不知道如何添加路径而不会导致更多的错误。
提前感谢。
I have perl programs that use Net::Finger and have run successfully from cron.daily in Fedora 11.
I just upgraded a server to Fedora 18 and these same perl programs no longer run from cron but run fine from command line when logged in as root.
The error is:
Can't locate Net/Finger.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .)
The path to the module is /root/perl5/lib/perl5/Net/Finger.pm but I can't figure out how to add the path without causing more errors.
Thanks in advance.

设置
PERL5LIB环境变量
15 15 * * 1-5 PERL5LIB=/root/perl5/lib/perl5 /usr/local/bin/perl my_script.pl
使用 -I 命令行开关
Use the -I command line switch
15 15 * * 1-5 /usr/local/bin/perl -I/root/perl5/lib/perl5 my_script.pl
使用 lib pragma in your perl script
Use the lib pragma inside your perl script
#! /usr/local/bin/perl
# my_script.pl: the script that does my thing
use lib '/root/perl5/lib/perl5';
use Net::Finger;
...
还要注意，cron作业的环境比命令行的环境更加稀疏，特别是cron环境的 $ PATH 变量可能不是你期望的。如果您没有指定Perl可执行文件的完整路径，请验证cron环境正在使用的 $ PATH ，并确保您运行的是正确版本的perl。
Also note that the environment of a cron job is much sparser than the environment of your command line, and in particular the cron environment's $PATH variable might not be what you expect. If you're not specifying the full path to the Perl executable, verify what $PATH the cron environment is using and make sure you are running the right version of perl.
