python - 找不到docker discord.py ffmpeg.exe

Question

我的代码在 Windows 上运行良好，出于稳定性原因，我只是不知道如何将它迁移到我的 docker 服务器，而我的旧 vm 把床弄脏了。下面是我的主要播放循环

async def main_playing_loop(vc, ctx):
    global skip
    while len(queued[str(ctx.guild.id)]) > 0:
        try:
            print(vc.is_playing())
            while vc.is_playing() or vc.is_paused():
                await asyncio.sleep(2)
                skip_func(vc)
                pass

        except AttributeError:
            pass
        try:
            url = str(queued[str(ctx.guild.id)][0])
            download_video(ctx, url)
            vc.play(discord.FFmpegPCMAudio(executable="ffmpeg.exe", source=str(ctx.guild.id) + ".mp3"))
            del queued[str(ctx.guild.id)][0]
        except:
            break

它在做什么的日志

我仍然有我在 win 上使用的 ffmpeg 的旧 exe，但这在 Ubuntu 上不起作用。感谢任何帮助。

您似乎正在尝试使用 Windows .exe在 Ubuntu Docker 上可执行。这不起作用，因为 Windows 应用程序只能在 Windows 上运行。因此，您需要找到一种方法来安装 Docker 容器 ffmpeg通过包管理器(apt 用于 Ubuntu)。
为此，我希望这另一个 thread有帮助。
