更新至 acro-v2.7b 后，Acro 软件包提供“！缺失数字，视为零。”

tag-icon • tag-icon texlive xparse acro texlive-2017 xtemplate
更新至 acro-v2.7b 后，Acro 软件包提供“！缺失数字，视为零。”

我对 texlive 2017 进行了更新（通过 tlmgr），然后出现了 acro 包错误，这是我以前从未遇到过的。

我已经提供了 MWE：

\documentclass{article}

\usepackage{acro}
\DeclareAcronym{RES}{
    short = RES ,
    long = Renewable Energy Sources ,
}
\listfiles
\begin{document}
    \ac{RES}
\end{document}

这是我对 \listfiles 的输出

这是日志文件中的错误：

! Missing number, treated as zero.
<to be read again> 
                   \l__acro_RES_long-plural_set_bool 
l.7 }

A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)

它可以链接到 acro 所需的软件包吗？它们似乎已更新。

该问题已在 v2.7c (2017/08/28) 中修复，目前正在向 CTAN 提交，并将很快在主要发行版中推出。
