我的机器上有 perl 版本 5.008003。我正在尝试使用 CPAN 安装 XML::Twig，但由于以下错误而失败。任何人都可以帮忙。

我所有的环境都有这个版本的 perl，所以我无法升级到最新版本。我只能解决这个版本的问题。

谢谢，

根据测试摘要，失败的似乎是 t/test_3_36.t 中的测试 43。如果你看它，它会测试 HTML::TreeBuilder&Amp;在解析 HTML 时如何处理（注意大写的 A）。取决于 HTML::TreeBuilder 的版本，&Amp; 可以处理为&amp;，实体为&。看来，在您的机器上安装的版本（3.13）中，它被（正确地）处理为&Amp;测试没有预料到的文字。

HTML::TreeBuilder 在使用 XML::Twig 解析 HTML 时使用。您也可以改用 HTML::Tidy（您需要安装它）。

这个问题是否重要到让你不安装模块，我不知道，你必须应用你最好的判断。

正如 ikegami 提到的，您在问题中给出的输出不是最佳的。没有必要复制所有警告（警告很多，我可能会显示较少的警告，但由于我希望他们鼓励用户安装 XML::XPathEngine，所以我将保持输出不变）。
