我遇到了模型“squaroid”的编译错误。我检查了代码好几次，但仍然找不到问题所在，这让我开始抓狂。我猜是某个地方缺少了一个标点符号。
相比之下，“三角形”模型运行正常。

答案1
如果你仔细查看错误消息，你会看到它说
I do not know the key '/tikz/below '
表示它正在寻找一个名为 的键below<space>。换句话说，你在某处有一个虚假的空格。在本例中，它是由 定义中的换行符引起的\pv：
\def\pv##1{%
\pgfkeysvalueof{/tikz/squaroid/##1}
}
右括号前的换行符会添加一个空格，因此将此定义更改为
\def\pv##1{%
\pgfkeysvalueof{/tikz/squaroid/##1}% <-- add % here
}
或者
\def\pv##1{\pgfkeysvalueof{/tikz/squaroid/##1}}
