Question

我正在研究Perl，当我运行我的脚本时，我得到错误说：

Can't locate XML/Simple.pm in @INC (you may need to install the  XML::Simple module) (@INC contains: /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl .) at cve_updater.pl line 43.

我搜索问题并得到更新或安装模块的答案。我同时使用两者：

cpan XML::DOM
cpan[1]> install XML::Simple

但结果如下：

我无法理解这是什么问题，感谢任何帮助和评论。

您已经获得了有关使CPAN安装正常工作的注释的帮助，但是大多数常见的Perl模块也可以从Ubuntu存储库安装。在这种情况下，您还应该能够sudo apt-get install libxml-simple-perl从Ubuntu安装它。如果这不是正确的软件包名称（我使用的是Debian而不是Ubuntu，那么Ubuntu可能已将其重命名），您可以使用apt-cache search XML::Simple获取匹配软件包的列表，然后用apt-cache show [package name]检查他们的详细信息，以确定您想要的那个。

但请注意，XML::Simple文档建议＆＃34;您真的不想在新代码中使用此模块。＆＃34; 如果您是编写新代码时，您应该查看另一个XML模块。我个人使用XML::Twig，恰好提供了一个simplify方法，它产生的输出非常类似于XML :: Simple，尽管你可能最好习惯更健壮的节点 - 基于界面。

Perl无法找到XML / Simple.pm
