我在 ubuntu 22.04 上使用 cpan 安装 XML::LibXML 时遇到问题。我已安装 libxml2 和 zlib1g。CPAN 报告它看到 libxml2：# 针对 libxml2 版本编译：21303# 正在运行

我在 ubuntu 22.04 上使用 cpan 安装 XML::LibXML 时遇到问题。我已安装 libxml2 和 zlib1g。CPAN 报告说它看到了 libxml2：

# Compiled against libxml2 version: 21303
# Running libxml2 version:          21303

所有软件包要求都已安装。（如果您需要查看版本号，我可以列出它们），但所有软件包都已存在）

有一些警告。一些测试失败。但安装本身失败：

我尝试的是：

cpan XML::LibXML

出现了几个关于某些被贬低的警告：
