我有几个使用 pgfkeys 的宏，是由一位朋友好心编写的（不幸的是，我不是这种高级 pgf/tikz 编码方面的专家）。
其中一个宏绘制了几个正方形及其之间的路径，每个参数都非常灵活且可定制。

问题。虽然正方形和五边形可以完美地协同工作，但当我在同一个主文件中使用五边形和正方形时，就会发生冲突，正方形或五边形的绘制（根据我在主文件中首先调用的那个）会变得奇怪；更准确地说，标签定位会变得混乱。这是一个 MWE：

% The pentagon of pentagons macro itself.
%
% This is the only user callable macro provided here.
%
% Takes a single parameter consisting of a list of key value pairs. These are
% processed using the keys mechanism (pgfkeys) built into TikZ, so they follow
% a familiar format.
%
% /pentagon/label/XXX = .... Set code to typeset label of arrow XXX
% /pentagon/arrowstyle/XXX = ... Set TikZ format for typesetting of arrow XXX.
% Overrides default.
% /pentagon/labelstyle/XXX = ... Set TikZ format for typesetting of label on
% arrow XXX. Overrides default.
%
% Here XXX denotes a sequence of integers identifying a generating cell by
% listing the numbers of the vertices (in order) of the corresponding face of
% the 4-simplex.
%
% You may use the path setting mechanism of pgfkeys to avoid too much path noise
% in a key value list. For example:
%
% \pentagon{/pentagon/label/.cd,
% 0=$0$, 1=$1$, 2=$2$, 3=$3$, 4=$4$,
% 01=$a$, 12=$b$, 23=$c$, 34=$d$, 04=$e$,
% 02=$f$, 03=$g$, 13=$h$, 14=$k$, 24=$l$,
% 012=$\alpha$, 034=$\beta$, 023=$\gamma$, 123=$\delta$, 134=$\epsilon$,
% 014=$\zeta$, 024=$\eta$, 234=$\theta$, 013=$\iota$, 124=$\kappa$,
% 0123=$\Theta$, 0124=$\Phi$, 0134=$\Psi$, 0234=$\Lambda$, 1234=$\Pi$,
% 01234=$\mathcal{F}$}

请注意，对于这些代码的一些细节，可能不适合进行后续提问。我也不确定在这个网站上用这么多行来交换代码是否合适，但只要不让帖子超出限制，就可以了。
