我正在尝试在我的系统上运行一个项目。我通过 GITHub 导入源代码，并在本地使用 WEBrick 运行它。当我这样做时，会打印以下错误：

我在“Sequel::AdapterNotFound”、“LoadError126”、“mysql_api.so”上搜索，但似乎无法获得任何有价值的信息。

我找到了这个页面：http ://permalink.gmane.org/gmane.comp.lang.ruby.sequel/2645 有人似乎有类似的问题，回复询问运行是否irb -rubygems -rmysql返回错误。我这样做了，它给了我一个错误，说计算机上缺少 LIBMYSQL.dll。我不确定这是否有用，但我想在这里提一下。

有没有人知道解决问题的线索，或者我要研究的方向？

重要的部分在这里：

LoadError: 126: Det går inte att hitta den angivna modulen(*Translation: Cannot find the given module*.) - C:/Ruby192/lib/ruby/gems/1.9.1/gems/mysql-2.8.1-x86-mingw32/lib/1.9/mysql_api.so

Ruby MySQL gem 引发了该错误，您通过运行该 IRB 命令确认了该错误。您可能需要将 LIBMYSQL.dll 文件添加到计算机，就像它说的那样。
