我在用 scrapy 爬虫的时候报错如下

scrapy.utils.signal][ERROR] Error caught on signal handler: > Traceback (most recent call last): File "/home/www/.local/lib/python3.4/site-packages/twisted/internet/defer.py", line 151, in maybeDeferred result = f(args, **kw) File "/usr/lib/python3.4/site-packages/pydispatch/robustapply.py", line 55, in robustApply return receiver(arguments, **named) File "/home/www/.local/lib/python3.4/site-packages/scrapy/extensions/telnet.py", line 63, in stop_listening self.port.stopListening() AttributeError: 'TelnetConsole' object has no attribute 'port'

这个错误如何处理
