我查找了如何使用 TikZ 制作使用鱼尾纹符号的 ERD，并找到了这。当我复制那里提供的代码时，没有任何问题，但是当将序言粘贴到我的代码中并将文档代码粘贴到文档部分时，我得到了使用 的每一行的一长串错误列表\draw。
其中大部分都与单位使用错误有关。修复这些错误后，我最终得到了底部的序言。但是我仍然收到“未定义控制序列”错误，我似乎无法修复。此外，即使我收到错误，我的最终 .pdf.document 也可以正常编译，我觉得这很奇怪。
谁能告诉我什么地方出了问题？
编辑：Marijn，指出我刚刚忘记了 \makeatletter% Crowsfoot notation。添加它并撤消我所做的更改解决了这个问题。可以找到需要它的解释这里。
