这是安装的标准输出：

$sudo cpanm XML::LibXML

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

libxml2-dev is already the newest version.

这是系统信息：

我认为相关的行是：

Checking for ability to link against libxml2...libxml2, zlib, and/or the Math library (-lm) have not been found.

因此，您已经了解了 libxml。你是否安装了合适的 zlib 包？尝试：

sudo apt-get install zlib1g-dev

然后再次尝试安装 XML::LibXML。

你为什么要为此使用 CPAN？如果您有标准操作系统安装程序提供的本机软件包，那么安装 CPAN 软件包通常是非常糟糕的主意。

Ubuntu 原生提供了很多 Perl 包，命名约定如下：包名总是以 开头lib，然后 Perl 包名 likeXML::LibXML转换为小写::替换为破折号-（XML::LibXML=> xml-libxml），最后-perl加上后缀。换句话说，本机包名称XML::LibXML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要的依赖项：

sudo apt-get install libxml-libxml-perl

如果您出于任何原因不喜欢此软件包，您可以使用sudo apt-get remove. 如果您使用 CPAN，则很难可靠地卸载它。

忽略了明显的：

sudo apt-get install --reinstall zlibc zlib1g zlib1g-dev

然后：

sudo cpanm XML::LibXML

作品！

也许这是新版本。我做了：

sudo apt-get install libxml2-dev

此模块构建并安装成功后
