无法导入moviepy.editor

Question

我试图使用moviepy库创建一个使用python的应用程序.我用它安装了:

pip install moviepy

我从MoviePy崩溃课程中找到了这个:

# Import everything needed to edit video clips
from moviepy.editor import *

尝试运行此行后,我收到此错误:

Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:42:59) [MSC v.1500 32     bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

    raise NeedDownloadError('Need ffmpeg exe. '
imageio.core.fetching.NeedDownloadError: Need ffmpeg exe. You can download it by calling:
  imageio.plugins.ffmpeg.download()

这里有什么问题,我该如何解决？

Answer 1

编辑:您现在可以将moviepy更新为v0.2.3.3,pip install --upgrade moviepy并在导入时自动安装ffmpeg moviepy.editor(#731)

在python控制台/ shell中运行(例如IPython/IDLE shell):

>>> import imageio
>>> imageio.plugins.ffmpeg.download()

Moviepy依赖于库imageio,它使用程序ffmpeg.它需要先下载它才能使用它,你可以使用上面的imageio命令下载它.
