安装manimlib时遇到UnicodeDecodeError: 'gbk' codec can't decode byte这个问题时，用我以下这种方式安装

今天安装manimlib的时候遇到了一些问题。先说我正确安装成功过程：

1.去https://github.com/3b1b/manim下载zip或者git clone下来，然后进到根目录，也就是进到名为manim的文件夹下，cmd执行：

# 自动安装requirements.txt这个文件里的所有包
python3 -m pip install -r requirements.txt

# 尝试运行一个Demo
python3 ./manim.py example_scenes.py SquareToCircle -pl

如果这两行代码都没问题，就会自动播放一段视频，如果你没设置过mediaplayer播放视频，会先让你设置一下才播放。

2.把第一步下载的manim中的manim.py文件和manimlib文件夹复制到你python安装路径下的Lib目录内，

比如我用的是Anaconda的Python，我的python路径是D:\ProgramData\Anaconda3_x64，那么我就把下载的manim.py文件和manimlib这个文件夹复制D:\ProgramData\Anaconda3_x64\Lib这个目录下。

3.测试是否安装成功，到桌面新建一个文件manim_demo.py然后写入以下内容并保存：

from manimlib.imports import *

class Shapes(Scene):
    def construct(self):
        circle = Circle()
        square = Square()
        line=Line(np.array([3,0,0]),np.array([5,0,0]))
        triangle=Polygon(np.array([0,0,0]),np.array([1,1,0]),np.array([1,-1,0]))

        self.add(line)
        self.play(ShowCreation(circle))
        self.play(FadeOut(circle))
        self.play(GrowFromCenter(square))
        self.play(Transform(square,triangle))

cmd cd到桌面或者Shift+右键，输入：

python -m manim manim_demo.py Shapes -pl

如果成功，会自动播放视频，并在manim_demo.py所在的目录下生成一个media的文件夹，视频就在里面：

至此已完成安装并验证安装成功。

以下是采坑经历：

刚开始我用pip install manimlib直接安装时出现了错误，安装失败：

具体报错代码：
