我通常在我的电脑上工作，但出于奇怪的原因，我不得不在另一台电脑上工作。以下代码以前可以正常工作，但在新电脑上却无法正常工作。我收到了很多我不明白的错误消息（我对 latex 的了解很少）。
我已经在 Windows 10 中安装了 basic-MiKTeX-2.9.7269-x64 和 Texmaker 5.0.3。代码是：

错误内容是：

还有更多。
我已经在很多论坛中寻找解决方案，但没有找到任何解决方案。
谁能帮我？
提前致谢。

我刚刚回答了一个非常相似的答案，问题总是一样的：您正在使用圆的弃用语法，，circle(<radius>)但应该使用circle[radius=<radius>]，这可以解决问题。

注意此问题已报告但使用非弃用的语法也可以解决这个问题。
