提出NeedDownloadError('需要ffmpeg exe.'NeedDownloadError:需要ffmpeg exe)

Question

我正在尝试执行一个非官方的Instagram API python库的调用,在我修复了几个依赖关系的错误之后,我就陷入了这个问题.

 File "C:\Users\Pablo\Desktop\txts_pys_phps_programacion\Instagram-API-python-master\InstagramAPI.py", line 15, in <module>
    from moviepy.editor import VideoFileClip
  File "C:\Python27\lib\site-packages\moviepy\editor.py", line 22, in <module>
    from .video.io.VideoFileClip import VideoFileClip
  File "C:\Python27\lib\site-packages\moviepy\video\io\VideoFileClip.py", line 3, in <module>
    from moviepy.video.VideoClip import VideoClip
  File "C:\Python27\lib\site-packages\moviepy\video\VideoClip.py", line 20, in <module>
    from .io.ffmpeg_writer import ffmpeg_write_image, ffmpeg_write_video
  File "C:\Python27\lib\site-packages\moviepy\video\io\ffmpeg_writer.py", line 15, in <module>
    from moviepy.config import get_setting
  File "C:\Python27\lib\site-packages\moviepy\config.py", line 38, in <module>
    FFMPEG_BINARY = get_exe()
  File "C:\Python27\lib\site-packages\imageio\plugins\ffmpeg.py", line 86, in get_exe
    raise NeedDownloadError('Need ffmpeg exe. '
NeedDownloadError: Need ffmpeg exe. You can download it by calling:
  imageio.plugins.ffmpeg.download()

Answer 1

错误消息中的最后两行提供了有价值的线索,我今天才安装了moviepy,所以我记得一个补救措施.

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

• 首先(sudo) pip install imageio,如有必要.
• 现在:import imageio然后imageio.plugins.ffmpeg.download().

Answer 2

如果您使用的是Ubuntu,请尝试:

sudo apt-get install ffmpeg

否则,如果您使用的是Windows,请尝试将ffmpeg.py第82行从auto = False更改为auto = True

它会自动将ffmpeg下载到正确的路径一次.然后import imageio写下来imageio.plugins.ffmpeg.download()

将工作.

Answer 3

这个包依赖于ffmpegPATH 中的可执行文件。

所以只需下载它，将其安装在某处，然后将安装目录添加到 PATH 中。确保可以通过键入以下内容访问它：

ffmpeg

从命令行。
