我正在尝试使用 CPAN 安装 XML::Parser perl 模块，但无法使其工作。下面是 CPAN 显示的输出，似乎表明 Expat 是问题所在。我已验证系统上安装了最新版本的 Expat。
安装这个对我们来说至关重要，我不知道下一步该怎么做。任何帮助都将不胜感激！

答案1
缺少的目标xsubpp是现代 perl 的核心 perl 的一部分，安装过程应该能够找到它的位置。您安装了哪个版本的 perl？当您尝试手动安装 XML::Parser（即下载 tarball，运行perl Makefile.PL && make）时会发生什么？听起来好像该perl Makefile.PL步骤无法找到xsubpp。您可能需要安装较新版本的ExtUtils::MakeMaker。
