我在Python中写了一个推送通知调度程序，以进行研究，该计划将处理通过Node .js发送通知。它在我的Mac上很漂亮，没有问题。我在其他地方构建了一台服务器来处理调度程序，因为它一直在打开。由于我无法控制的原因，该服务器运行Debian Wheezy。但是，每当我尝试运行代码时，我都会得到：
File "scheduler.py", line 148, in send_notifications
s.enter(5, 1, notification, kwargs={'notify': 'Welcome to the Study!'})
TypeError: enter() got an unexpected keyword argument 'kwargs'
仍然可以在我的Mac上工作。我已经检查了一下，以确保我所有的导入库都是通过PIP3下载的，但是我无法弄清楚我的问题是什么。我已经在Stackoverflow和其他各种来源上检查了其他错误的人，但是我不确定他们是否有与我的问题相似的问题，主要是课堂呼叫问题，我认为这不是那样。我已经附加了代码，尽管我不确定是否有帮助。我的意思是，这不是世界上最干净的代码，但是我比Python更加流利的移动开发人员。有什么建议吗？

更新：
hmm，经过进一步检查，看起来像Wheezy系统默认为3.2，并且不会接受任何比这更高的请求。看起来它接受了"参数"，但是正如克劳斯所建议的那样，参数还需要通知与已发送通知的区域相同。
所以现在看起来像
s.enter(5, 1, notification, argument={'notify: Welcome to the Study!'})
#This for loop fills the scheduler with every notification that needs to be sent.
for member in listOfTimeDelays:
notification = 'notify: ' + listOfNotificationText[listOfNotificationNames[i]]
#takes one of the time delays, a priority (I just made them all 1), and then sends the right notification
s.enter(member, 1, notification, argument={notification)
#Incriments the counter to make sure you get the next notification
i = i+1
感谢您对此的帮助。
sched.Scheduler仅接受python 3.3的 kwargs参数。我想您正在Debian机器上运行较旧版本。
