记录一次错误

scrapy 测试 scrapy bench

出现

AttributeError: 'NoneType' object has no attribute 'nextcall'

Traceback (most recent call last):
  File "D:\pythoninstalllive\lib\site-packages\twisted\internet\defer.py", line 857, in _runCallbacks
    current.result = callback(  # type: ignore[misc]
  File "D:\pythoninstalllive\lib\site-packages\scrapy\core\engine.py", line 187, in <lambda>
    d.addBoth(lambda _: self.slot.nextcall.schedule())

找到错误发生具体位置

def _next_request_from_scheduler(self) -> Optional[Deferred]:
        assert self.slot is not None  # typing
        assert self.spider is not None  # typing
