我可以运行简单的动画，但是当我开始充分利用它时，它给了我一个错误。
为了使用数学表达式，您需要将它们括在
Tex()Tex("$A = \\frac{1}{2} \\times \\text{base} \\times \\text{height}$")
或使用
MathTex()MathTex("A = \\frac{1}{2} \\times \\text{base} \\times \\text{height}")
如果你甚至使用Python的原始字符串，你可以跳过双
\\MathTex("A = \frac{1}{2} \times \text{base} \times \text{height}")
