我试图调用 matplotlib.animation.ArtistAnimation 从一系列 png 图像制作动画，但出现与 ffmpeg 连接的错误。我在 Ubuntu 14.04 上安装了 Anaconda。我收到的错误消息是:
UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.
warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')
/home/ohm/anaconda2/lib/python2.7/site-packages/matplotlib/animation.py:782: UserWarning: MovieWriter ffmpeg unavailable

+ ' Try running with --verbose-debug')
RuntimeError: Error creating movie, return code: 1 Try running with --verbose-debug
我尝试过sudo apt-get install ffmpeg，但没有这样的包。有人知道我缺少什么包裹吗？
最佳答案
conda update conda
conda install --channel https://conda.anaconda.org/conda-forge ffmpeg
