$您不能在垂直模式下使用“\lastsavedimageresourcepages”。在 Linux 上使用 TexLive 2018 时出错$

更新：

感谢下面的评论，在下面的 MWE 中添加\thebefore\lastsavedimageresourcepages有效！但为什么呢？我所有的 latex 文件中有数千个地方使用这种类型的代码，而没有\thein ，而且总是有效。

所以现在我必须去查找并编辑每个地方并\the在那里添加？我不明白为什么要进行这种会破坏当前乳胶代码的更改。

原始问题

下面的 MWE 在lualatex昨晚我在 Vbox 上全新安装 TL 2018 的情况下仅在 Linux Manjaro 上进行编译时出现此错误。

在另一个 Linux ubuntu 上，同一个文件用 lualatex 编译时没有错误，但用 TeXLive 编译时，可能已经一个月或两个月没有更新了。这是唯一的区别。

那么最新的 TL 2018 似乎出了点问题？请注意，此 MWE 仅适用于 lualatex，不适用于 pdflatex。\saveimageresource仅在使用时才定义lualatex。

\documentclass[11pt]{article}
\usepackage{hyperref}
\usepackage{pgffor}  
\usepackage{graphicx}

\begin{document}

\saveimageresource{math_228A_HW1.pdf}%use any other PDF here to run
\foreach \n in {1,...,\lastsavedimageresourcepages} % for lualatex
{
    \includegraphics[width=0.88\textwidth,page=\n]{math_228A_HW1}

}  

\end{document}

查看上述版本，我发现pgffor.sty已更新：

  pgffor.sty    2019/01/05 v3.1 (3.1)
  pgfrcs.sty    2019/01/05 v3.1 (3.1)

这可能是问题所在吗？

任何 pdf 文件都可用于运行上述操作。由于我无法在此处附加 PDF 文件。因此您可以使用任何 pdf 文件。

上面的代码已经运行了很长时间，没有问题。在我全新安装最新的 TL 2018 后，它现在在新的 Linux 上失败了。

您观察到的是 PGF 中的一个错误：https://sourceforge.net/p/pgf/bugs/507/

这是损坏的提交：https://sourceforge.net/p/pgf/git/ci/acdfa1450bd2beda4d6865bb2717e4d6f628c875/

目前的解决方法是在寄存器中添加前缀\the或从旧版本恢复内部定义。

\documentclass{article}
\usepackage{pgffor}

\makeatletter
\def\pgffor@dots@value@process#1{%
        \expandafter\pgffor@dots@stripcontext#1\pgffor@@stop%
        \expandafter\pgffor@dots@charcheck\pgffor@dotsvalue\pgffor@@stop%
  \let#1=\pgffor@dotsvalue% 
}
\makeatother

\begin{document}
\saveimageresource{example-image-a.pdf}
\foreach \n in {1,...,\lastsavedimageresourcepages} { }
\end{document}

~~但是，这样诸如此类的功能\foreach \n in {1,...,1e+1} { }就不再起作用了。~~此功能是在 PGF 3.1 中引入的，所以之前无论如何都无法正常工作。
