为了在每一页的页脚中显示当前页码和总页数（例如，12 页中的第 4 页），我使用了lastpage包并放置了语句：
\rfoot{\thepage\ of \pageref{LastPage}}
就在\begin{document}声明之前。
当我运行时lualatex doc-1.tex，最后收到以下警告。
LaTeX Warning: Reference `LastPage' on page 11 undefined on input line 209.
[11]
Package lastpage Warning: Rerun to get the references right on input line 210.
AED: lastpage setting LastPage
LaTeX Warning: Reference `LastPage' on page 12 undefined on input line 210.
[12] (/Users/amanda/ltx/s/build/store/upload/doc-1.aux)
LaTeX Warning: There were undefined references.
LaTeX Warning: Label(s) may have changed. Rerun to get cross-references right.
这使得页脚看起来类似于：
4 of ??
并且生成的文档没有\tableofcontents。重新运行它可以解决问题。
有没有办法可以避免这种情况？我不想第二次重新运行命令来确保正确（因为会同时生成许多不同的文档）。
如果有帮助，我已经分享了我运行的用于生成文档的 lualatex 代码。
