Perl:错误消息:无法在@INC 中找到 ... [英] Perl: error message: can´t locate ... in @INC

问题描述

我正在尝试编译这个脚本，但我有这样的消息:

I am trying to compilate this scrip, but I have this message:

在@INC 中找不到 Email/Address.pm(@INC 包含:C:/strawberry/perl/lib C:/草莓/perl/site/lib C:strawberryperlvendorlib .) 在 C:/strawberry/perl/lib/Regexp/Common/Email/Address.pm 第 9 行.BEGIN 失败——编译在 C:/strawberry/perl/lib/Regexp/Common/Email/中止地址.pm 第 9 行.在 (eval 1) 第 1 行的 require 中编译失败.BEGIN 失败——编译在 C:examplesscript2.pl 第 4 行中止.

Can't locate Email/Address.pm in @INC (@INC contains: C:/strawberry/perl/lib C:/ strawberry/perl/site/lib C:strawberryperlvendorlib .) at C:/strawberry/perl/ lib/Regexp/Common/Email/Address.pm line 9. BEGIN failed--compilation aborted at C:/strawberry/perl/lib/Regexp/Common/Email/ Address.pm line 9. Compilation failed in require at (eval 1) line 1. BEGIN failed--compilation aborted at C:examplesscript2.pl line 4.

我不明白，因为我真的有这个根

I don´t understand because I really have this root

C:/strawberry/perl/lib/Regexp/Common/Email/Address.pm

C:/strawberry/perl/lib/Regexp/Common/Email/Address.pm

有人知道为什么我在编译我的脚本时会出现这个错误信息吗?

非常感谢

我试着用这句话:

使用 lib 'C:/strawberry/perl/lib/Regexp/Common/Email';

use lib 'C:/strawberry/perl/lib/Regexp/Common/Email';

并将这两句话作为注释:

and putting as comment these two sentences:

use Regexp::Common qw[Email::Address];
  use Email::Address

然后我收到此错误

Global symbol "%RE" requires explicit package name at C:examplesscript2.pl lin
e 10.Execution of C:examplesscript2.pl aborted due to compilation errors.

我看过perldiag

全局符号%s"需要明确的包名(F) 您已经说过use strict"或use strict vars"，这表明所有变量必须是词法范围的(使用my"或state")，使用our"预先声明，或者明确限定为说出全局变量在哪个包中(使用::").

Global symbol "%s" requires explicit package name (F) You've said "use strict" or "use strict vars", which indicates that all variables must either be lexically scoped (using "my" or "state"), declared beforehand using "our", or explicitly qualified to say which package the global variable is in (using "::").

但我觉得这对我来说有点理论化，因为我知道你必须在代码的乞求中使用句子使用"来使用包.

but I find it a little theoretical for me by I understand that you have to use packages by using the sentence 'use' at the begging of the code.

顺便说一下，这是我的代码:

By the way this is my code:

 use Regexp::Common qw[Email::Address];
  use Email::Address;
  while (<>) {
  my (@found) = /($RE{Email}{Address})/g;
  my (@addrs) = map $_->address, Email::Address->parse("@found");
  print "X-Addresses: ", join(", ", @addrs), "
";
  }

我从我之前问过的一个问题中获得了这个代码.

I get this code from a question I asked before.

推荐答案

我认为问题是，你确实有 Regexp::Common::Email::Address 已安装.但是，您还需要 Email::Address，这是一个单独的模块.也就是说，你还应该在C:/strawberry/perl/lib/Email/Address.pm中安装了一个模块.

I think the issue is, you do have Regexp::Common::Email::Address installed. However, you also need Email::Address, which is a separate module. That is to say, you should also have a module installed in C:/strawberry/perl/lib/Email/Address.pm.

尝试使用 cpan 安装 Email::Address，参见 安装缺少的 Perl 模块的最简单方法是什么?

Try using cpan to install Email::Address, see What's the easiest way to install a missing Perl module?

更新一点解释:

Perl 模块以分层方式组织.:: 包分隔符等于模块库路径中的一个目录.模块的全名/含义源自包本身的名称和安装路径.假设您有名为 Restaurant::Bill、Hat::Bill 和 Names::Male::Bill 的模块.您将拥有三个名为 Bill.pm 的不同文件，但它们代表非常不同的概念.它们将通过它们在您的模块库中的路径来区分.

Perl modules are organized in a hierarchical manner. The :: package separator is equal to a directory in your module library path. The full name/meaning of the module is derived from both the name of the package itself and the path in which it is installed. Suppose you had modules called Restaurant::Bill, Hat::Bill, and Names::Male::Bill. You would have three different files called Bill.pm, but they would represent very different concepts. They would be distinguished from each other by their paths in your module library.
