我正在使用解决方案这里用于 scala 支持，但这无法正确地为 scala 代码着色，并且在处理 lstset 时引发许多错误——% ! Package keyval Error: breakatwhitespace undefined.有人能帮我找出这个简单例子的问题吗？

\usepackage{listings}

}
% A number of keyval errors occur here - basically
% nothing in lstset is recognized. Errors look like:
% ! Package keyval Error: breakatwhitespace undefined.

编辑：添加后\listfiles，这是我看到的文件列表

正如 Peter 在其评论中指出的那样，您的 TeX 发行版似乎已经严重过时了。是时候清除它上面的锈迹，并启动您的包管理器了。
另外，后面少了一个逗号breakatwhitespace=true。
此外，自 2013 年 10 月起，该listings软件包附带了 Scala 的语言定义（在lstdvrs.dtx文件）。如果您更新了 TeX 发行版，则您不必在文件中从头开始重新定义该语言.tex即可使用它。
