perl - 在 Perl 中，无法在 @INC 错误中找到 packgeName.pm

Question

这是一个模块math.pm有 2 个基本函数加法和乘法:

package Math;
use strict;
use warnings;
use Exporter qw(import);
our @EXPORT_OK = qw(add multiply); 

sub add {
my ($x, $y) = @_;
return $x + $y;
}

sub multiply {
my ($x, $y) = @_;
return $x * $y;
}

1;

这是脚本 script.pl调用 add 函数:

#!/usr/bin/perl
use strict;
use warnings;

use Math qw(add);
print add(19, 23);

它给出了一个错误:

can't locate math.pm in @INC <@INC contain: C:/perl/site/lib C:/perl/lib .> at C:\programs\script.pl line 5. BEGIN failed--compilation aborted at C:\programs\script.pl line 5.

如何解决这个问题呢？

Answer 1

use lib

Adding a use lib statement to the script will add the directory to @INC for that specific script. Regardless who and in what environment runs it.

You just have to make sure to have the use lib statement before trying to load the module:

use lib '/path/to/module';
use Math qw(add);
