问题描述
这是安装的标准输出：
$sudo cpanm XML::LibXML
--> Working on XML::LibXML
Fetching http://www.cpan.org/authors/id/S/SH/SHLOMIF/XML-LibXML-2.0014.tar.gz ... OK

Try setting LIBS and INC values on the command line
Or get libxml2 from

If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.
Also, you may try to run perl Makefile.PL with the DEBUG=1 parameter
to see the exact reason why the detection of libxml2 installation
failed or why Makefile.PL was not able to compile a test program.

我尝试手动安装libxml2，但仍然遇到同样的问题。
另外，我检查了libxml2-dev：
sudo apt-get install libxml2-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
libxml2-dev is already the newest version.

这是系统信息：

最佳解决方案
我认为相关的是：
Checking for ability to link against libxml2...libxml2, zlib, and/or the Math library (-lm) have not been found.
所以，你已经覆盖了libxml。你安装了适当的zlib包吗？尝试：
sudo apt-get install zlib1g-dev
然后再次尝试安装XML :: LibXML。
次佳解决方案
你为什么要为此使用CPAN呢？如果您具有标准操作系统安装程序提供的本机程序包，则通常非常不明智地安装CPAN程序包。
Ubuntu本身提供了大量的Perl包，具有以下命名约定：包名始终以lib开头，然后Perl包名如XML::LibXML转换为小写，::替换为dash -(XML::LibXML => xml-libxml)，最后是-perl后缀被添加。换句话说，XML::LibXML的本机包名称为libxml-libxml-perl。
因此，在您的情况下，您只需运行此命令，它将自动提取所有必需的依赖项：
sudo apt-get install libxml-libxml-perl
如果您因任何原因不喜欢此软件包，可以使用sudo apt-get remove将其卸载。如果使用CPAN，则很难可靠地卸载它。
第三种解决方案
忽略了显而易见的：
sudo apt-get install --reinstall zlibc zlib1g zlib1g-dev
然后：
sudo cpanm XML::LibXML
作品！
