我是Perl的新手.运行脚本时出现以下错误:

Can't locate URI.pm in @INC (@INC contains: /usr/local/packages/perl_remote/5.6.1/lib/5.6.1/i86pc-solaris /usr/local/packages/perl_remote/5.6.1/lib/5.6.1 /usr/local/packages/perl_remote/5.6.1/lib/site_perl/5.6.1/i86pc-solaris /usr/local/packages/perl_remote/5.6.1/lib/site_perl/5.6.1 /usr/local/packages/perl_remote/5.6.1/lib/site_perl .) at (eval 2) line 3.

可能的原因是什么,以及如何让脚本工作.任何帮助将不胜感激.

我试图使用Perl 复制我的C#/ XPath代码在Linux上的作用.我复制并粘贴了Perl和XML中的例8-6中的代码.如果我理解正确,我应该能够运行该Perl代码,将此代码放在终端中

xmlPerl.pl mydatafile.xml "/inventory/category/item/name"

但是当我尝试运行Perl文件时,它不起作用.这是错误:

[root@Perl ~]# perl xmlPerl.pl
Can't locate XML/XPath.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib64/perl5/site_perl/5.8.7/x86_64-linux-thread-multi /usr/lib64/perl5/site_perl/5.8.6/x86_64-linux-thread-multi /usr/lib64/perl5/site_perl/5.8.5/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl/5.8.7 /usr/lib/perl5/site_perl/5.8.6 /usr/lib/perl5/site_perl/5.8.5 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib64/perl5/vendor_perl/5.8.7/x86_64-linux-thread-multi /usr/lib64/perl5/vendor_perl/5.8.6/x86_64-linux-thread-multi /usr/lib64/perl5/vendor_perl/5.8.5/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl/5.8.7 /usr/lib/perl5/vendor_perl/5.8.6 /usr/lib/perl5/vendor_perl/5.8.5 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at xmlPerl.pl line 3.
BEGIN failed--compilation aborted at xmlPerl.pl line 3.

我究竟做错了什么？我认为它与我的代码开头的XML和XPath名称有关.我是否需要安装一些东西才能使用XPath框架？我在RedHat 5.5上运行.

我正在尝试编译这个脚本,但我有这样的信息:

无法在C中找到@INC中的Email/Address.pm(@INC包含:C:/ strawberry/perl/lib C:/ strawberry/perl/site/lib C:\ strawberry\perl\vendor\lib.):/strawberry/perl/lib/Regexp/Common/Email/Address.pm第9行.BEGIN失败 - 编译在C:/ strawberry/perl/lib/Regexp/Common/Email/Address.pm第9行中止.编译失败需要在(eval 1)第1行.BEGIN失败 - 编译在C:\ examples\script2.pl第4行中止.

我不明白,因为我真的有这个根

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

有人在我尝试编写我的脚本时知道为什么会出现此错误消息吗？

非常感谢

我试着用这句话:

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

并将这两句话作为评论:

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

然后我收到这个错误

Global symbol "%RE" requires explicit package name at C:\examples\script2.pl lin
e 10.Execution of C:\examples\script2.pl aborted due to compilation errors.

我看了一下perldiag

全局符号"%s"需要显式包名(F)您说过"use strict"或"use strict vars",表示所有变量必须是词法范围(使用"my"或"state"),声明预先使用"我们的",或明确限定说明全局变量所在的包(使用"::").

但我发现它对我来说有点理论上我明白你必须在代码的乞讨时使用句子'use'来使用包.

顺便说一下这是我的代码:

 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(", ", …

我需要检索perl库统计信息和分布所在的路径。该路径是运行脚本所必需的。我在计算机集群上。谁能帮我？

谢谢

运行从Oracle数据库获取内容并将结果导出为CSV的Perl脚本时,尝试通过命令行运行时出现此错误:

Can't locate Text/CSV.pm in @INC (@INC contains:

/usr/lib/perl5/site_perl/5.16.2 /usr/lib/perl5/site_perl .) at
./OracleScript.pl line 4. BEGIN failed--compilation aborted at
./OracleScript.pl line 4.

我解释这意味着没有安装模块.所以,我尝试使用以下命令安装它:

/usr/bin/perl -MCPAN -e'install Text::CSV_pm'

我收到此错误:

Database was generated on Mon, 06 Oct 2014 10:41:02 GMT Warning:
Cannot install Text::CSV_pm, don't know what it is. Try the command

    i /Text::CSV_pm/

to find objects with matching identifiers.

任何人都能解释我的问题,以及如何解决这个问题？

如何安装需要编译C代码的perl模块？我确实知道使用PPM和CPAN的一般安装.提前致谢.

我有Solaris 10,我正在尝试运行Perl程序.

我安装了两个perl版本:

/usr/bin/perl 版本5.8.4

和

/usr/local/bin/perl 版本5.12.3

我已经安装了DBI软件包(它已安装在这里/usr/perl5/site_perl/5.8.4/sun4-solaris-64int/auto/DBI/.packlist),我通过执行不同perl版本的Perl程序得到的问题是(在ubuntu中工作正常).

我已经尝试了很多方法,但没有得到如何在solaris上运行我的Perl程序.有人可以帮忙吗.

以下是我的计划.实际上它是由@Borodin重新定义的.非常感谢他.

我尝试在其他 shell 脚本中运行 perl 脚本，但遇到了以下问题：

无法在@INC中找到new.pm（@INC包含：/usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/ perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl

我已经专门设置了附加本地 Perl 脚本的路径，即我的 Perl 脚本（test.pl）中的“new.pm”，但错误仍然出现。(perl -V) 显示我本地 Perl 的路径。我还使用命令“PERL5LIB”在我的配置文件中进一步设置了“new.pm”的路径。

但是，当我在命令行上运行脚本时：

./test.pl 

它确实有魅力。

附言。she-bang 线已正确设置。附言。平台：linux，OS_vers=2.6.32-5-amd64

我试图让我在网站上找到的示例代码工作:

    #!/usr/bin/perl

    use v5.10;
    use WWW::Mechanize;
    use WWW::Mechanize::TreeBuilder;

    my $mech = WWW::Mechanize->new;
    WWW::Mechanize::TreeBuilder->meta->apply($mech);

    $mech->get( 'http://htmlparsing.com/' );

    # Find all <h1> tags
    my @list = $mech->find('h1');

    # or this way

    # Now just iterate and process
    foreach (@list) {
        say $_->as_text();
    }

当我运行它时,我收到此消息:

有没有人对正在发生的事情有任何想法？
