使用最新版本的ebproof软件包时，我遇到了编译错误。如何解决这个问题？
这是 MWE：
\documentclass[a4paper,12pt]{article}
\usepackage{mathtools,amssymb}
\usepackage{ebproof}
\begin{document}
\begin{prooftree}
\hypo{ \Gamma, A &\vdash B }
\infer1[abs]{ \Gamma &\vdash A\to B }
\hypo{ \Gamma \vdash A }
\infer2[app]{ \Gamma \vdash B }
\end{prooftree}
\end{document}
并且.log是：

2021年1 月 28 日更新：维护者向ebproofCTAN 发送了更新，因此您可以更新（您的镜像可能需要一两天才能更新），然后您可以删除该undo-recent-deprecations行。
需要ebproof更新以替换已弃用的\box_set_eq_clear:NN。\box_set_eq_drop:N正如错误消息所暗示的那样，一段时间内，您可以通过expl3在undo-recent-deprecations加载之前加载 来解决这个问题ebproof：
