即使我安装了请求的 MovieWriter (ffmpeg) 也不可用

Question

我正在运行这个命令。

import bar_chart_race as bcr
bcr.bar_chart_race(df=covid_df,filename=None,figsize=(3.5,3),title='Covid-19 Cases by State',n_bars=10)

出现以下错误

Exception: You do not have ffmpeg installed on your machine. Download
                            ffmpeg from here: https://www.ffmpeg.org/download.html.
                            
                            Matplotlib's original error message below:

                            Requested MovieWriter (ffmpeg) not available

已经安装了模块

D:\py\Scripts>pip install ffmpeg-python
Requirement already satisfied: ffmpeg-python in d:\py\lib\site-packages (0.1)

D:\py\Scripts>

Answer 1

ffmpeg-python 模块和 ffmpeg 是两个不同的东西。您需要从错误消息的链接安装 ffmpeg
