Twitch 聊天记录器在 python3.7 中因 websocket 错误而崩溃

Question

所以，我今天尝试在 Python 3.7 中制作 Twitch Chat(IRC) 记录器。运行 python -m pip install pipenv pipenv --python 3.7 pipenv install setproctitle pipenv install twitchio pipenv run pip install --upgrade git+https://github.com/Gallopsled/pwntools.git@dev3 后，当我运行 logger.py 时出现此错误：

2019-12-20
Task exception was never retrieved

  File "/usr/lib/python3.7/asyncio/tasks.py", line 449, in wait_for
    raise futures.TimeoutError()

During handling of the above exception, another exception occurred:

这是来自 logger.py 的相关代码，它似乎已连接，但在 10 秒超时后崩溃。我在使用 .env 文件的 TMI_TOKEN 环境变量中使用 oauth:oathkeyFromTwitch 作为我的密码。

#!/usr/bin/env python3

if len(sys.argv) > 1:
    channel = sys.argv[1]

bot = commands.Bot(
    # set up the bot
    irc_token=os.environ['TMI_TOKEN'],
    client_id=os.environ['CLIENT_ID'],
    nick=os.environ['BOT_NICK'],
    prefix=os.environ['BOT_PREFIX'],
    initial_channels=[os.environ['CHANNEL'], channel]
)

@bot.event
async def event_ready():
    'Called once when the bot goes online.'
    print(f"{os.environ['BOT_NICK']} is online!")
    ws = bot._ws  # this is only needed to send messages within event_ready
    await ws.send_privmsg(os.environ['CHANNEL'], f"/me has landed!")


@bot.event
async def event_message(ctx):
    """Runs every time a message is sent in chat."""

    # make sure the bot ignores itself and the streamer
    if ctx.author.name.lower() == os.environ['BOT_NICK'].lower():
        return

    await bot.handle_commands(ctx)

    if 'hello' in ctx.content.lower():
        await ctx.channel.send(f"Hi, @{ctx.author.name}!")

if __name__ == "__main__":
    from commands import Handler as command_handler
    bot.run()

我的代码痴迷的大脑在这里缺少什么？

Answer 1

initial_channels=[os.environ['CHANNEL'], channel] 需要成为：

initial_channels=[os.environ['CHANNEL']] 或 initial_channels=[channel]

commands.Bot 的相关代码就这样实例化了：

class Bot(Client):
    def __init__(self, irc_token: str, api_token: str=None, *, client_id: str=None, prefix: Union[list, tuple, str],
                 nick: str, loop: asyncio.BaseEventLoop=None, initial_channels: Union[list, tuple]=None,
                 webhook_server: bool=False, local_host: str=None, external_host: str=None, callback: str=None,
                 port: int=None, **attrs):
