关于manimgl使用中LaTeX出错

Question

电脑配置：
Mac mini
Apple M2 Pro
内存: 16GB
Sonoma 14.6.1

Python: 3.10.11
我在网上找了好多教程，在电脑上装了manimgl。我也一同学习了用manimgl制作动画。
但是在写代码的时候，我遇到了一点小问题，以下是代码：

from manimlib import *


FILL_COLOR = BLUE_E
FILL_OPACITY = 0.5


class ManimScene(Scene):
    def construct(self):
        square = Polygon(np.array([-1, 2, 0]), np.array([-5, 2, 0]), np.array([-5, -2, 0]), np.array([-1, -2, 0]))
        self.play(GrowFromCenter(square))
        square_1 = Polygon(np.array([-3, 2, 0]), np.array([-3, -2, 0]), np.array([-5, -2, 0]), np.array([-5, 2, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_1))
        square_2 = Polygon(np.array([-3, 0, 0]), np.array([-3, -2, 0]), np.array([-1, -2, 0]), np.array([-1, 0, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_2))
        square_3 = Polygon(np.array([-3, 2, 0]), np.array([-3, 0, 0]), np.array([-2, 0, 0]), np.array([-2, 2, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_3))
        square_4 = Polygon(np.array([-2, 0, 0]), np.array([-1, 0, 0]), np.array([-1, 1, 0]), np.array([-2, 1, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_4))
        square_5 = Polygon(np.array([-2, 1, 0]), np.array([-1.5, 1, 0]), np.array([-1.5, 2, 0]), np.array([-2, 2, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_5))
        square_6 = Polygon(np.array([-1.5, 1, 0]), np.array([-1, 1, 0]), np.array([-1, 1.5, 0]), np.array([-1.5, 1.5, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_6))
        square_7 = Polygon(np.array([-1.5, 1.5, 0]), np.array([-1.25, 1.5, 0]), np.array([-1.25, 2, 0]), np.array([-1.5, 2, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_7))
        square_8 = Polygon(np.array([-1.25, 1.5, 0]), np.array([-1, 1.5, 0]), np.array([-1, 1.75, 0]), np.array([-1.25, 1.75, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_8))
        square_9 = Polygon(np.array([-1.25, 1.75, 0]), np.array([-1.125, 1.75, 0]), np.array([-1.125, 2, 0]), np.array([-1.25, 2, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_9))
        square_10 = Polygon(np.array([-1.125, 1.875, 0]), np.array([-1, 1.875, 0]), np.array([-1, 1.75, 0]), np.array([-1.125, 1.75, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_10))
        square_11 = Polygon(np.array([-1.125, 2, 0]), np.array([-1.0625, 2, 0]), np.array([-1.0625, 1.875, 0]), np.array([-1.125, 1.875, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_11))
        square_12 = Polygon(np.array([-1.0625, 1.9375, 0]), np.array([-1.0625, 1.875, 0]), np.array([-1, 1.875, 0]), np.array([-1, 1.9375, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_12))
        square_13 = Polygon(np.array([-1.0625, 2, 0]), np.array([-1.0625, 1.9375, 0]), np.array([-1.03125, 1.9375, 0]), np.array([-1.03125, 2, 0]), fill_color=FILL_COLOR, fill_opacity=FILL_OPACITY)
        self.play(GrowFromCenter(square_13))

        text = TexText("$\frac{1}{3}$")
        text.move_to(RIGHT)
        self.play(GrowFromCenter(text))




if __name__ == "__main__":
    from os import system
    system("manimgl {} ManimScene".format(__file__))

错误信息：

显示：Missing $ inserted.
应该是

text = TexText("$\frac{1}{3}$")

这句话出了问题。
我在网上搜索了LaTeX公式的语法，但是感觉代码没什么问题。
望各位能帮我解决一下，谢谢！

以下回复参考：皆我百晓生、券券喵儿等免费微信小程序作答:

根据你提供的代码和错误信息，问题出在TexText的参数上。在LaTeX中，\frac用于表示分数，但它需要两个参数，分别表示分子和分母。在你的代码中，\frac只有一个参数1，所以会出现错误。

为了解决这个问题，你需要为\frac提供一个分母。例如，如果你想表示分数$\frac{1}{3}$，你可以修改代码如下：

text = TexText("$\frac{1}{3}$")

这样应该可以解决你遇到的问题。
