您好，我目前收到一个用于防止垃圾邮件的齿轮错误。 这是我得到的错误
File "C:\Users\User\Documents\stream\cogs\spamdetect.py", line 19, in on_member_join
last_reset = datetime.strptime(self.settings[server.id]["time_since_last_reset"], "%Y-%m-%d %H:%M:%S.%f")
TypeError: strptime() argument 1 must be str, not None
我不确定是什么原因导致此错误，齿轮似乎工作了一段时间，然后它引发了此错误。
这里是我的工作

错误似乎在第19行，即last_reset = datetime.strptime(self.settings[server.id]["time_since_last_reset"], "%Y-%m-%d %H:%M:%S.%f")
非常感谢您的帮助。
答案 0 :(得分：0)
代码中的这一行存储None到设置中：
if "time_since_last_reset" not in self.settings[server.id]:
self.settings[server.id]["time_since_last_reset"] = None
然后有一些玩家加入，由于尝试解析无时间，您会收到错误消息。
有很多解决方案，最直接的解决方案是：
if self.settings[server.id]["time_since_last_reset"] is None:
reset_time = 999 # a big number to trigger the timeout now
else:
last_reset = datetime.strptime(self.settings[server.id]["time_since_last_reset"], "%Y-%m-%d %H:%M:%S.%f")
reset_time = (datetime.now() - last_reset).total_seconds()
