包含獨立 TikZ 影像時如何合併子前導碼？

我想將 TikZ 圖像包含到我的文件中。我希望它是獨立的，這樣我就不必用它的所有序言來污染我的主要文件。根據standalone手動的（第 22 頁）可以將這些前導碼包含在subpreambles選項中。但是當我設定時，subpreambles=true我收到一個錯誤，並且前導碼無論如何都會被忽略。如何合併 TikZ 程式碼的前導碼？

這是我的主文檔的程式碼：

\documentclass{book}
\usepackage{tikz}
\usepackage{standalone}
\begin{document}
Text ...
\begin{figure}
    \includestandalone[subpreambles=true]{mytikz}
    \caption{My TikZ picture}
    \label{fig:tikz:my}
\end{figure}
\end{document}

這是我的圖片的程式碼mytikz.tex：

\documentclass[tikz]{standalone}
\usepackage{tikz}
\tikzstyle{object_representation} = [
    align = center,
    draw = black,
    fill = white,
    minimum width = 2cm,
    minimum height = 2cm,
    rectangle,
    rounded corners,
]
\begin{document}
\begin{tikzpicture}[node distance = 3cm]
    \node (foo) [object_representation] {Foo};
\end{tikzpicture}
\end{document}

這是我得到的錯誤：

ABD: EveryShipout initializing macros

Package xkeyval Warning: key `subpreambles' has been disabled on input line 7.

(mytikz.tex

請嘗試以下操作：

\documentclass{book}
\usepackage{tikz}
\usepackage[subpreambles=true]{standalone} % <--- option should be here

\begin{document}
Text ...
\begin{figure}
    \includestandalone{mytikz}
    \caption{My TikZ picture}
    \label{fig:tikz:my}
\end{figure}
\end{document}

編輯：我會mytikz很快寫出您的文件，並使用最近的語法來確定形狀樣式：

\documentclass[tikz]{standalone}% <-- it is sufficient to has `tikz` only here
\tikzset{object_representation/.style = {% <---
    align = center,
    draw = black,
    fill = white,
    minimum width = 2cm,
    minimum height = 2cm,
    rectangle,
    rounded corners}
        }

\begin{document}
\begin{tikzpicture}
    \node (foo) [object_representation] {Foo};
\end{tikzpicture}
\end{document}
