Discordbot 使用线程引发“运行时错误：set_wakeup_fd 仅适用于主线程”仅在 linux 上

Question

我使用线程模块同时启动 Web 服务器和 Discodbot。一切都在 Windows 上运行良好，但是一旦我将它加载到我的 Linux 服务器上，我就会收到错误消息：

Starting Bot
Exception in thread Bot:
Traceback (most recent call last):
  File "/usr/lib/python3.8/asyncio/unix_events.py", line 95, in add_signal_handler
    signal.set_wakeup_fd(self._csock.fileno())
ValueError: set_wakeup_fd only works in main thread

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3.8/threading.py", line 932, in _bootstrap_inner
    self.run()
  File "/home/webadmin/discordbot/bot/moduls/m_threadingmaker.py", line 15, in run
    self.client.run(self.args[0])
  File "/home/webadmin/discordbot/bot/venv/lib/python3.8/site-packages/discord/client.py", line 614, in run
    loop.add_signal_handler(signal.SIGINT, lambda: loop.stop())
  File "/usr/lib/python3.8/asyncio/unix_events.py", line 97, in add_signal_handler
    raise RuntimeError(str(exc))
RuntimeError: set_wakeup_fd only works in main thread

我已经从 python 3.7 升级到 python 3.8，但仍然是同样的错误。

这是我的代码：main.py（网络服务器工作）

dcbot = m_threadingmaker.myThread("Bot", client, secrets.token)
webserver = m_threadingmaker.myThread("Flask", app, 'localhost', '7010')

#webserver.start()
dcbot.start()

M_threadingmaker.py

from threading import Thread

class myThread (Thread):
   def __init__(self, name, client, *args):
      Thread.__init__(self)
      self.name = name
      self.client = client
      self.args = args

   def run(self):
      print("Starting " + self.name)
      if self.name == "Flask":
          self.client.run(host=self.args[0], port=self.args[1])
      else:
          self.client.run(self.args[0])
      print("Exiting " + self.name)

谢谢大家帮助我

我建议您client.start()在异步协程中使用，而不是client.run()在单独的线程中使用。
