manim是用python开发的数学可视化的工具, 作者热衷于做一些数学知识的普及视频, 因而做了这个库, 后来开源了这个库, 我们得以使用, 下面这篇文章介绍了如何安装manim以及它所依赖的各种软件, 过程虽然麻烦, 但是并不难。
环境介绍 我使用win10(64位)系统, python3.6已经安装完毕, 并且已经安装好了jupyter notebook ,
使用pip安装manimlib 使用如下命令安装manimlib
如果你安装失败, 并且提示编码错误, 请先将你的win10系统的默认编码改成”utf-8”。
安装FFmpeg FFmpeg是一个视频处理工具, 安装方法很简单, 只需要现在文件, 放到一个你喜欢的位置即可。
下载地址: https://www.gyan.dev/ffmpeg/builds/ffmpeg-git-full.7z
解压得到这几个文件:
接下来需要将ffmpeg的所在文件夹添加到Path路径中, 我们文章后面”设置环境变量”中会介绍
安装pycairo 我们首先下载已经编译好的库, 下载地址在这里:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#pycairo
由于我的python是3.6 64位, 因此我下载的是”pycairo‑1.20.0‑cp36‑cp36m‑win_amd64.whl”;
然后在命令行输入:
1 pip install PathToTheFile/pycairo‑1.20.0‑cp36‑cp36m‑win_amd64.whl
很快就能安装完毕, 输出是:
1 2 3 Looking in indexes: http://mirrors.aliyun.com/pypi/simple/ Processing d:\notebooks\pycairo-1.20.0-cp36-cp36m-win_amd64.whl pycairo is already installed with the same version as the provided wheel. Use --force-reinstall to force an installation of the wheel.
安装Miktex
打开你下载的安装文件, 你会看到这个, 点击”下一步”
一般不需要完整安装, 只需要基本功能, 选择第一个
选择一个服务器, 选择China的服务器, 速度比较快
选项下载文件夹, 点击下一步就开始下载了, 记住你的这个下载文件夹, 后面要打开这个文件夹
打开你下载好的文件, 然后双击’setup-4.1.1-x64.exe’来安装:
安装Sox
下载地址是: https://sourceforge.net/projects/sox/files/sox/14.4.2/
设置安装路径, 点击”install”, 基本上这样就安装完毕了, 后面需要将sox的安装路径添加到环境变量”path”中, 最后会讲
安装 jupyter-manim 使用pip安装:
1 pip3 install jupyter-manim
我们会看到安装成功的提示:

设置环境变量 上面安装了一些windows软件, 然而我们的python想要调用这些软件(比如ffmpeg)需要将这些软件的安装路径配置到Path环境变量中。
编辑”Path”这个变量, 然后新增”ffmpeg”的安装路径:
测试安装是否成功 为了能使用魔法%%manim, 我们首先要引入 jupyter_manim:
下面, %%manim就可以使用了, 我们测试一下:
1 2 3 4 5 6 7 8 9 10 %%manim Shapes from manimlib.scene.scene import Scenefrom manimlib.mobject.geometry import Circlefrom manimlib.animation.creation import ShowCreationclass Shapes (Scene ): def construct (self ): circle = Circle() self.play(ShowCreation(circle))
