我在使用 degruyter latex 模板处理文章时遇到了一些问题。除了语法树和 lfg AVM 之外，其他一切都正常。我正在使用 xelatex 进行编译，并且使用 forest 和 langsci-avm 进行编译语言学和左转作为选项。有人能帮我吗？谢谢。这是最简代码。

\usepackage[linguistics]{forest}
\usepackage[lfg]{langsci-avm}

\begin{document}
\begin{forest}
[IP[DP][I']]
\end{forest}
\avm[style=plain]{
[pred & `silue']}
\end{document}
错误信息如下：
! Misplaced \noalign.
\bottomrule ->\noalign
{\ifnum 0=`}\fi \@aboverulesep =\aboverulesep \global...
l.67 \end{forest}
I expect to see \noalign only after the \cr of
an alignment. Proceed, and I'll ignore this case.
! Missing } inserted.
<inserted text>
}
l.67 \end{forest}
I've inserted something that you may have forgotten.
(See the <inserted text> above.)
With luck, this will get me unwedged. But if you
really didn't forget anything, try typing `2' now; then
my insertion and my current dilemma will both disappear.
! Missing \endgroup inserted.
<inserted text>
\endgroup

DeGruyter 包将所有 tabular 重新定义为booktabstabular，这搞砸了内部使用常规 tabular 环境的包。幸运的是，他们还提供了一种撤消更改的方法，因此对于任何forest导致此错误的环境，您都可以使用：
\AtBeginEnvironment{forest}{\baretabulars}
如果langsci-avm命令是宏而不是环境，则可以使用from\avm修补命令：\pretocmdetoolbox
\usepackage{etoolbox}
\pretocmd{\avm}{\baretabulars}{}{\fail}
如果修补由于您尝试修补的特定命令的定义方式而失败，则宏\fail将返回未定义的控制序列错误，在这种情况下您需要找到另一种方法来修补该特定命令。
这是一个最小的工作示例（并且您的非工作示例应该是这样的）。
