未定义控制序列 \draw 和 \end{tikzpicture}

我正在尝试用 LaTex 画一幅画。当我编译文件时，它给出了未定义的控制序列错误。我尝试将它与我的其他文档进行比较，但找不到错误所在。我在这里附上了我的文件。提前感谢您的帮助！

您的其中一个复制/粘贴内容中有此行

(-5,1) node (28) [] {$\bullet$)

因此它会打开括号，其余部分是 TeX 的正常行为；抱怨代码中遇到的最遥远和最不相关的事情。我有时认为 TeX 会读取两次以找到最模糊的错误消息。

另请检查您的包裹申报，您实际上装载了graphicx五次，pgf三次。

TikZ 加载pgf所有pgf*模块并且也加载graphicx。
