我上次更新MiKTeX已经是一年多了，到目前为止，下面的 MWE 仍然有效：
\begin{filecontents*}{tst.tex}
\begin{tikzpicture}[auto]
% placing the nodes
\node[signal] (input) {};
\node[
sum,
right = of input
] (left sum) {};
\node[
block,
right = of left sum
] (controller) {$#3$};
\node[
block,
right = of controller
] (system) {$#5$};
\node[
sum,
right = of system
] (right sum) {};
\node[
block,
above = of right sum
] (Gd) {$#7$};
\node[
signal,
above = of Gd
] (disturbances) {};
\node[
branch,
right = of right sum
] (branch) {};
\node[
signal,
right = of branch
] (output) {};
\node[
signal,
below = of left sum
] (feedback) {};
% connecting the nodes
\draw
[->] (input) -- node {$#1$} (left sum);
\draw
[->] (left sum) -- node {$#2$} (controller);
\draw
[->] (controller) -- node {$#4$} (system);
\draw
[->] (system) -- (right sum);
\draw
[->] (disturbances) -- node {$#6$} (Gd);
\draw
[->] (Gd) -- node {$#8$} (right sum);
\draw
(right sum) -- (branch);
\draw
[->] (branch) -- node {$#9$} (output);
\draw
(branch) |- (feedback);
\draw
[->] (feedback) -- node[pos = .95] {$-$} (left sum);
\end{tikzpicture}
\end{filecontents*}
\documentclass{scrartcl}
\usepackage{
tikz,

\usepackage{siunitx} % for test reasons
\usetikzlibrary{positioning}
\tikzset{

sum/.style = {
draw,

inner sep = 0pt,
minimum size = 2mm

\newcommand*\Y{\underline Y}
\newcommand*\G{\mathbf G}
\newcommand*\D{\underline D}
\newcommand*\K{\mathbf K}
\newcommand*\E{\underline E}
\newcommand*\R{\underline R}
\ExplSyntaxOn
\cs_generate_variant:Nn
\cs_set_protected:Nn {cV}
\NewDocumentCommand{\loadFile}{mO{0}m}{\tl_set_from_file:Nnn
\l_tmpa_tl {}{#3}
\cs_set_protected:cV {__tempFuction:\prg_replicate:nn {#2}{n}}
\l_tmpa_tl
\cs_new_eq:Nc #1 {__tempFuction:\prg_replicate:nn {#2}{n}}}
\ExplSyntaxOff
\loadFile\controlWithoutNoise[9]{tst}
\begin{document}
\controlWithoutNoise{\R}{\E}{\K}{\underline0}{\G}{\D}{\G_d}{}{\Y}
\end{document}
因此，我认为这部分的语法（我从这里)：
\ExplSyntaxOn
\cs_generate_variant:Nn
\cs_set_protected:Nn {cV}
\NewDocumentCommand{\loadFile}{mO{0}m}{\tl_set_from_file:Nnn
\l_tmpa_tl {}{#3}
\cs_set_protected:cV {__tempFuction:\prg_replicate:nn {#2}{n}}
\l_tmpa_tl
\cs_new_eq:Nc #1 {__tempFuction:\prg_replicate:nn {#2}{n}}}
\ExplSyntaxOff
这次改变了。有办法让它重新工作吗？
提前感谢您的帮助和努力！
答案1
\tl_set_from_file:Nnn已被弃用。您必须替换它并更改参数的顺序：
\begin{filecontents*}{tst.tex}

right = of input

\node[

\node[

\node[

\node[
