Ensure that a matplotlib writer library is installed 如何确保安装 matplotlib writer library？

问题遇到的现象和发生背景

https://github.com/JackMcKew/pandas_alive 项目中 python绘制动图气泡图
作者原文提到了:

If you get an error such as `TypeError: 'MovieWriterRegistry' object is not an iterator`, this signals there isn't a writer library installed on your machine.
如果出现诸如“TypeError:”MovieWriterRegistry“对象不是迭代器”之类的错误，这表示您的计算机上没有安装writer库。
此软件包使用[matplotlib.animation函数](https://matplotlib.org/3.2.1/api/animation_api.html)，因此需要编写器库。

)

报错内容

This package utilises the https://matplotlib.org/3.2.1/api/animation_api.html, thus requiring a writer library.

Ensure to have one of the supported tooling software installed prior to use!
