Perl 无法在@INC 中定位模块 [英] Perl cannot locate module in @INC

问题描述

我正在运行 Centos 6.4 和 perl 5.10.我有一个使用 DateTime 模块的简短脚本.但是，当我运行我的脚本时，我收到以下错误消息，告诉我无法找到各种模块，因为它们不在库路径中.

I am running Centos 6.4 and perl 5.10. I have short script which uses the DateTime module. However when I run my script I get the following error message telling me various modules cannot be located as they are not in the library path.

Can't locate Params/Validate.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/lib64/perl5/DateTime/Duration.pm line 11.
BEGIN failed--compilation aborted at /usr/lib64/perl5/DateTime/Duration.pm line 11.

Compilation failed in require at ./jr_fix_western_filestore.perl line 39.
BEGIN failed--compilation aborted at ./jr_fix_western_filestore.perl line 39.

所有这些软件包都是通过 yum 安装的.例如 yum install perl-Params-Validate.x86_64 和 yum install perl-DateTime.x86_64.yum 安装不应该把这些模块放在@INC 中吗?

All of these packages have been installed via yum. eg yum install perl-Params-Validate.x86_64 and yum install perl-DateTime.x86_64. Should the yum install not place these modules in @INC?

我也尝试通过 cpan 安装软件包，但这似乎想先下载大量依赖项，但不可避免地会失败.

I have also tried to install the packages via cpan but this seems to want to download lots of dependencies first and inevitably fails.

当我尝试在 cpan 中安装 Module::Build 时，出现以下错误

When I try to install Module::Build in cpan, I get the following error

有什么指点吗?

rpm -ql perl-Params-Validate 返回

我不确定@INC 是否搜索了这些路径

I'm not sure if these paths are searched by @INC

然而 locate Validate.pm 什么都不返回

推荐答案

似乎您为 RHEL/Centos 4 配置了 RPMforge，但您使用的是 Centos 6:

Seems that you have RPMforge configured for RHEL / Centos 4 but you use Centos 6:

安装:perl-Params-Validate x86_64 0.95-1.el4.rf

Installing: perl-Params-Validate x86_64 0.95-1.el4.rf

按照本网站的说明进行全局 dist 升级以修复损坏的依赖项(我很幸运，不需要重新安装).然后安装你想要的 perl 包.

Follow the instructions from this site and do global dist upgrade to fix broken dependencies (I you're lucky reinstall won't be needed). Then install perl packages you want.
