Linux Perl 无法在@INC 中定位模块

Perl cannot locate module in @INC

提问by moadeep

I am running Centos 6.4 and perl 5.10. I have short script which uses the DateTimemodule. 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.

我正在运行 Centos 6.4 和 perl 5.10。我有使用该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。

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.

All of these packages have been installed via yum. eg yum install perl-Params-Validate.x86_64and yum install perl-DateTime.x86_64. Should the yum install not place these modules in @INC?

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 安装不应该将这些模块放在@INC 中吗？

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

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。

Any pointers?

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

我不确定@INC 是否搜索了这些路径

However locate Validate.pmreturns nothing

但是locate Validate.pm什么都不返回

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

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

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

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

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

按照此站点的说明进行全局 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。

I'm late to the discussion, but had the same problem. Here is how I solved it.

我迟到了讨论，但遇到了同样的问题。这是我解决它的方法。

CPAN was giving me the same error because an older version of was installed under yum. I updated the package via yum and was able to move forward.

CPAN 给了我同样的错误，因为在 yum 下安装了旧版本。我通过 yum 更新了软件包，并且能够继续前进。
