【问题描述】：
长期以来，我一直在尝试使用 python(2.4) 解析和运行 javascript 网页。不幸的是，我不能使用 qt,webkit，所以大多数基于 python 的无头浏览器都被排除在外。然而，我最近在 perl（使用 perl 5.8.8）中发现了 WWW::Scripter，它似乎也是 javascript 的脚本引擎。我还安装了运行它所需的 javascript 插件。
use WWW::Scripter;
$w = new WWW::Scripter;
$w->use_plugin('JavaScript'); # packaged separately
$w->get('some javascript website');
print $w->content;
好吧，它会打印出很多错误并最终终止，并且输出似乎与预期不符。我尝试了 3-4 个站点，但结果相同。通过预期的输出，我的意思是可以从谷歌浏览器的检查元素中看到的源代码。 知道我在使用 perl 脚本时做错了什么吗？其次，让javascript引擎运行以解析python2.4或perl（甚至ruby，约束不能使用qt）中的网站的任何快速替代方法 希望我能提出我的问题而不会造成太多混乱。

您遇到了什么错误？你到底为什么要使用已有十多年历史的 Perl 5.8？
-
感谢您的回复。我在服务器机器上工作，因此升级需要很多请求:(虽然我已经发起了请求，但在那之前我需要对我所拥有的感到满意。当我在路透社上运行它时，我正在粘贴前几行错误网站。
