我一直在遵循BugZilla 安装文档，并使用mod_perl w / apache2。 一切都相当顺利，bugzilla页面似乎得到渲染和正确服务，但现在重新启动Apache时，我得到了一些错误信息，每当页面加载时，虚拟主机的错误日志中显示大量的错误。
这开始发生后，我添加了这两行文档说在任何其他mod_perl指令之前添加，所以我把它放在我的httpd.conf的顶部附近。
PerlSwitches -w -T PerlConfigRequire /var/www/bugzilla/mod_perl.pl 现在，当apache2重新启动，我得到这个。

Perl开关-w启用警告。 当你编写一个新的Perl脚本的时候，这是很好的，但是当你运行你信任的旧代码的时候，这个脚本可能会适得其反。 在这种情况下，它将喷出有关不推荐使用的语法的警告。
尝试删除-w ，看看是否清理。
我还没有做过很多的testing，看是否会破坏任何东西，但是在我的系统中，如果我在以下位置编辑文件，错误/警告将被删除：
/var/www/bugzilla/lib/Return/Value.pm
注释掉这一行：
#Carp::cluck "Return::Value is deprecated" unless $NO_CLUCK;
可能需要一些testing来检查它是否破坏了任何东西，但是从外观上看，这一行并没有做太多的事情。
