如果这是非常基础的，请原谅，但我是一个初学者。
我在 tkz-euclide 示例中收到错误：我不知道密钥/tikz/triangle和错误：我不知道密钥。/tikz/input我猜我缺少某个包或某些库，但我如何找出是哪些呢？
非常感谢
抱歉，这是代码和错误消息：

And here are the errors:

答案1
您需要定义三种样式（在 pgfmanual 中定义的颜色）并在我的源代码中。这是我的错，我应该对它们进行评论。这个想法是与 pgfmanual 示例的代码进行比较，供主要想做数学运算的用户使用。
.log 文件中指示的错误是： Package pgfkeys Error: I do not know the key '/tikz/triangle'。这是由于 管理不善而导致的错误pgfkeys。此处的tkz-euclidepgfkeys 用于管理选项和样式。我建议您查看 中如何使用样式，pgfmanual因为您可以在 中使用它们tkz-euclide。
help lines不是 的选项\tkzDrawCircles。这里的选项是线条的粗细、颜色、样式（虚线或实线）（请参阅下面如何获取网格）
\colorlet{input}{red!80!black}
\colorlet{output}{red!70!black}
\colorlet{triangle}{orange!40}
