【问题描述】：

所以我正在运行以下代码，它是更大文件的一部分。即使我已经安装了 ffmpeg 并将其设置为 $PATH 变量，它仍然会抛出以下错误。我在运行 OSX El Capitan 的 Mac 上。此代码使用 python 3.5.2 的 discord 模块。

            author_channel = (message.author).voice_channel
            voice = await media_bot.join_voice_channel(author_channel)
            player = await voice.create_ytdl_player(video)
            player.start()

Traceback (most recent call last):
      File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/discord/voice_client.py", line 431, in create_ffmpeg_player
        p = subprocess.Popen(args, stdin=stdin, stdout=subprocess.PIPE, stderr=stderr)
      File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 947, in __init__
        restore_signals, start_new_session)
      File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 1551, in _execute_child
        raise child_exception_type(errno_num, err_msg)
    FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'

    The above exception was the direct cause of the following exception:

    Traceback (most recent call last):
      File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/discord/client.py", line 307, in _run_event

【解决方案1】：

对我有用的解决方案是从源代码构建 ffmpeg。

cd /usr/src
sudo git clone https://github.com/FFmpeg/FFmpeg.git
cd FFmpeg
sudo ./configure --enable-openssl
sudo make 
sudo make install

前面的命令应该工作，只是准备等待很长时间才能构建。
