我正在尝试编写一个 Python 程序,在 Mac OS 10.11.16 上使用 MoviePy 将 MP4 文件转换为 GIF。我用:
import moviepy.editor as mp
我收到一条错误消息,说我需要打电话imageio.plugins.ffmpeg.download()
这样我就可以下载ffmpeg了。我用:
import imageio
imageio.plugins.ffmpeg.download()
这给了我以下错误:
Imageio: 'ffmpeg.osx' was not found on your computer; downloading it now.
Error while fetching file: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)>.

我肯定有互联网连接。我发现this https://superuser.com/questions/624561/install-ffmpeg-on-os-x链接,并尝试使用 Homebrew 和 Static 版本进行安装,但都不起作用。看来自己编译它对我来说有点太先进了(我只是简单地研究了一下)。我用了imageio.plugins.ffmpeg.download()
处于空闲状态。我读到了一些有关使用 PyCharm 运行 MoviePy 代码的内容,但我得到了相同的初始错误。 ffmpeg 目前在我的/usr/local/bin
文件夹。欢迎任何建议。感谢您的帮助。
编辑:我正在使用Python 3.6.1
