每次我尝试连接到 Ibt 时，都会收到运行时错误“此事件循环已在运行”。我不记得我之前有过这个错误，可能是我开始了一个没有结束的循环。这是代码和错误日志：

ib=IB()
ib.connect('127.0.0.1',7497,12,10)


---------------------------------------------------------------------------

    522         if events._get_running_loop() is not None:
    523             raise RuntimeError(

RuntimeError: This event loop is already running

任何想法我该如何解决这个问题？

你应该写：

from ib_insync import *

util.startLoop()
ib=IB()
ib.connect('127.0.0.1', 7497, clientId=12)
