Imageio: ‘ffmpeg-linux64-v3.3.1’ was not found on your computer; downloading it now.

在使用Python的moviepy模块的时候，报出以下错误：

错误原因：
imageio模块下载ffmpeg的时候，无法连接网络。
下载的路径可以参看:
./site-packages/imageio/core/fetching.py:63
./site-packages/imageio/plugins/ffmpeg.py:70

wget https://github.com/imageio/imageio-binaries/raw/master/ffmpeg/ffmpeg.linux64

mv ffmpeg.linux64 ~/.imageio/ffmpeg/
