我正在写一份文档，其中包含一些有关该listings包的定制内容：
lstjson通过以下方式定义的环境\lstnewenvironment\restsection用作命令，但用以下命令\section包装节头：\lstinline- 一个
\lstitem命令，它的作用与上面一样\item
该结构似乎有效，但随着文档的增长，它停止编译。错误是
Package xkeyval: `LANGUAGE' undefined in families `lst'
下面是一个（非）工作示例。奇怪的是，它似乎取决于我使用列表的次数：如果您删除足够多的\lstitems 或“某种字段”行，它将编译。

答案1
我通过评论收到了对提供的 mwe 的答复（感谢 daleif），但主文档中仍然出现问题。然而，我仍然必须将它们隔离到新的 mwe 中，因为文档现在由于解决方法而正常工作\clearpage。与此同时，我将用 daleif 的答复结束此篇。
LANGUAGE 是此处的关键提示。您是否尝试过将此添加到序言中：\nouppercaseheads\pagestyle{headings}回忆录中的默认标题是大写的，因此大写也会影响变量参数。关闭它们更容易，无论如何，我认为不再推荐使用大写标题。
