重启Apache后该功能不可用

我对 perl 和 apache 相当陌生，我的代码似乎有一个小问题。

我有 3 个文件：

hw.pm

package hw;

sub calc {
    my $num1 = shift;
    my $num2 = shift;
    return $num1 + $num2;
}
1;

startup.pl

use lib qw(path to where hw.pm is located);
1;

hel.pl

#!/usr/bin/perl -w
use hw;
use CGI qw(:standard);
print header;

my $ans = calc(5,4);
print $ans;

我重新启动 apache 没有问题，但是当我从浏览器中出现错误 Can't located hw.pm in @INC

Startup.pl 是否应该已将其包含在 @INC 中？或者我错过了什么？

我正在使用 perl v5.10.1 和 Apache2 v2.2.16

I am fairly new with perl and apache and seem to be having a small problem with my code.

I have 3 files:

hw.pm

package hw;

sub calc {
    my $num1 = shift;
    my $num2 = shift;
    return $num1 + $num2;
}
1;

startup.pl

use lib qw(path to where hw.pm is located);
1;

hel.pl

#!/usr/bin/perl -w
use hw;
use CGI qw(:standard);
print header;

my $ans = calc(5,4);
print $ans;

I have no problem restarting apache but when I access hel.pl from the browser I get an error Can't locate hw.pm in @INC

Should the startup.pl have already included it in @INC? Or am I missing something?

I am using perl v5.10.1 and Apache2 v2.2.16

Perl 未找到 hw.pm。

尝试将此行从startup.pl复制

use lib qw(path to where hw.pm is located);

到hel.pl，替换其中的“use hw;”。但首先要确保路径正确。

@INC - 数组 @INC 包含列表
寻找 Perl 脚本的地方
通过 do EXPR 、 require 进行评估
，或使用构造。最初它
由任何 -I 的参数组成
命令行开关，后跟
默认 Perl 库，可能
“/usr/local/lib/perl”，然后是
“.”，代表当前
目录。

Perl is not finding hw.pm.

Try copying this line from startup.pl

use lib qw(path to where hw.pm is located);

to hel.pl, replacing the "use hw;" there. But first make sure the path is correct.

@INC - The array @INC contains the list
of places to look for Perl scripts to
be evaluated by the do EXPR , require
, or use constructs. It initially
consists of the arguments to any -I
command line switches, followed by the
default Perl library, probably
"/usr/local/lib/perl", followed by
".", to represent the current
directory.
