【问题描述】：
我正在运行 Centos 6.4 和 perl 5.10。我有使用 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。
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 ./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 install 不应该把这些模块放在@INC 中吗？
我也尝试过通过 cpan 安装软件包，但这似乎想先下载很多依赖项并且不可避免地失败。

当我尝试在 cpan 中安装 Module::Build 时，出现以下错误

任何指针？

我不确定@INC 是否搜索了这些路径
但是locate Validate.pm 什么也没返回
【问题讨论】：
-
检查 yum 安装包的位置。
-
rpm -ql perl-Params-Validate，另外你是否安装了 make (yum groupinstall "Development Tools")？ -
要检查包的位置，请尝试在终端中使用
locate。例如。检查locate Validate.pm -
rpm -ql的输出清楚地表明你安装的包是perl 5.8 包。但是，您告诉我们您使用的是 5.10。很奇怪。 -
perl -V将回答您关于是否搜索这些目录的最后一个问题。
