manim无法绘制正方形

Question

问题遇到的现象和发生背景

刚安装好manim，全程按照https://docs.manim.org.cn/安装，然后试了一下官方文档的入门教程的代码，结果一试就出问题了

问题相关代码

from manimlib import *

class SquareToCircle(Scene):
    def construct(self):
        square= Square()
        square.set_fill(RED)
        square.rotate(PI / 4)
        self.add(square)

运行结果

运行结果就是那个方形一直不显示，但是我画圆形的时候是没有问题的，也是add(cirle)
全程的提示信息：

我的写法和文档里的一模一样，但是就是运行不了。求解答T-T

Python版本是多少

不知道你的代码具体是什么

我这边操作了下：

from manimlib import *

class SquareToCircle(Scene):
    def construct(self):

        circle = Circle()
        circle.set_fill(BLUE, opacity=0.5)
        circle.set_stroke(BLUE_E, width=4)
        square = Square()
        square.set_fill(RED)
        square.rotate(PI / 4)
        self.add(square)
        self.play(ShowCreation(square))
        self.wait()
        self.play(ReplacementTransform(square, square))
        self.wait()

正常的输出了一个旋转45度的正方形
你看下你是否忘记修改这行代码为

self.play(ReplacementTransform(square, square))

demo里面是

self.play(ReplacementTransform(square, circle))
你如果画正方形的话自己把这个换一下。
上面是我测试的代码

你可以试下是否正常。
