有一些关于类似问题的主题，但没有一个被证明是有效的。我尝试在 github 页面上询问也没有运气。
当我尝试标准命令时：
gem install libxml-ruby
我收到安装程序找不到 libxml2.dll 的错误。我发现了一个存在类似问题的 stackoverflow 线程，并在此处遵循用户指南，了解在哪里获取丢失的库以及在哪里包含它们。
如果我使用以下命令向安装命令添加参数以指向缺少库的目录：
gem install libxml-ruby -- with-xml2-include=C:\Ruby200\include\libxml2 --with-iconv-include=C:\Ruby200\include
我现在收到一个错误，安装程序在我的 C:\Ruby200\include 目录中找不到“iconv.h”头文件。

如果有人对下一步调查什么或可能的解决方案有任何建议，我将不胜感激。很长一段时间以来，我一直对此感到困惑，每当我遇到一个带有 libxml 的项目时都会回到它，并且很乐意接受任何建议。
非常感谢。
