python - Discord bot python : discord. errors.ClientException: ffmpeg was not found

Question

我正在尝试制作一个在语音 channel 中播放音乐的 discord 机器人。它连接到语音 channel ，但不播放任何内容。它还会在控制台中给出错误。

我在 Windows 上，我正在使用 discord.py 重写。

我的代码:

import discord, random, datetime, asyncio, nacl, ffmpeg

TOKEN = 'What token'

client = discord.Client()

@client.event
async def on_message(message):
if message.content.lower() == '$play':
    if message.content.lower() == '$play':
        channel = client.get_channel(547155964328149007)
        vc = await channel.connect()
        vc.play(discord.FFmpegPCMAudio('mp3.mp3'), after=lambda e: print('done', e))
        vc.is_playing()
        vc.pause()
        vc.resume()
        vc.stop()

@client.event
async def on_ready():
    print('Logged in as {0.user}'.format(client))

client.run(TOKEN)

错误:

Traceback (most recent call last):
  File "D:\Python35\lib\site-packages\discord\client.py", line 218, in _run_event
    await coro(*args, **kwargs)
  File "discord_bot.py", line 90, in on_message
    vc.play(discord.FFmpegPCMAudio('mp3.mp3'), after=lambda e: print('done', e))
  File "D:\Python35\lib\site-packages\discord\player.py", line 165, in __init__
    raise ClientException(executable + ' was not found.') from None
discord.errors.ClientException: ffmpeg was not found.

人们似乎对 ffmpeg/avconv was not found in your PATH environment variable 有类似的问题，但解决方法是从网站下载 ffmpeg 并将其放入他们的 PATH，但这对我不起作用。

此外，我只能在 JavaScript 中找到解决我的问题的方法，而我正在用 Python 3 编写机器人程序。

以下是我研究的一些链接:

You need to add FFmpeg to your path

您可以直接使用参数executable指定FFmpeg可执行文件:

vc = await channel.connect()
vc.play(discord.FFmpegPCMAudio(executable="C:/path/ffmpeg.exe", source="mp3.mp3"))
