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()
才能下载 ffmpeg。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。我找到了这个链接,并尝试使用 Homebrew 和静态版本进行安装,但都没有成功。似乎自己编译它对我来说有点太高级了(我只是简单地研究了一下)。我imageio.plugins.ffmpeg.download()
在 IDLE 上使用过。我读了一些关于使用 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
文件夹中。欢迎任何建议。感谢您的帮助。
编辑:我正在使用 Python 3.6.1
