Twitch 聊天记录器因 python3.7 中的 websocket 错误而崩溃

Question

So, I tried to make a Twitch Chat(IRC) logger in Python 3.7 today. After running 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 and I get this error when I run logger.py:

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:

Here's the relevent code from logger.py and it seems to connect but after the 10 second timeout crashes. I am using oauth:oathkeyFromTwitch as my password in the TMI_TOKEN env varrible using a .env file.

    initial_channels=[os.environ['CHANNEL'], channel]
)

@bot.event

    '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()

What is my code addled brain missing here?

Answer 1

initial_channels=[os.environ['CHANNEL'], channel] needed to become either:

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

the relevent code from commands.Bot instantiates thusly:

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):
