错误仅在Linux上出现，在Mac上没有：获取了意外的关键字参数“kwargs”

Question

我用python为research编写了一个push通知调度器，它将处理通过NODE.js发送通知的问题。它在我的Mac电脑上运行得很好，没有问题。我在其他地方构建了一个服务器来处理调度程序，因为它一直处于运行状态。服务器运行Debian Wheezy，原因我无法控制。但是，每当我尝试运行代码时，我会得到：

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'

在我的Mac电脑上仍然工作得很好。我已经检查了所有导入的库是否都通过pip3下载了，但我就是不知道我的问题是什么。我在stackoverflow和其他各种源上检查过其他有这个错误的人，但我不确定他们是否有和我的问题类似的问题，主要是类调用问题，我不认为这是那样的。我已经附上了代码，虽然我不确定这是否有帮助。我的意思是，它不是世界上最干净的代码，但我在移动开发方面比python更流利。有什么建议吗？你知道吗

#Dictionary of what the above short names connect to. Take short names, and connect them to full length notifications

    'tvenergy': 'Your television utilizes 2 watts of energy when not in use.  It will be powered off when not in use from now on.',
    'window': 'The bedroom window has been opened to cool the room.'}

#test code, can be used to test the notification system
time1 = now+timedelta(seconds=30)
time2 = now+timedelta(seconds=60)
time3 = now+timedelta(seconds=90)
testList = [dt.datetime(now.year, now.month, now.day, time1.hour, time1.minute, time1.second), 
    dt.datetime(now.year, now.month, now.day, time2.hour, time2.minute, time2.second),

#empty list to be filled
listOfTimeDelays = [0, 0, 0]

#takes all the lists above, and figures out how long each of them are from when I started the study.
#This creates a giant list of delays from the day I hit start
def calculateMinutesIntoSeconds(testList, listOfTimeDelays):
    i = 0
    for member in testList:
        print(member)
        listOfTimeDelays[i] = ((member-dt.datetime(now.year, now.month, now.day, now.hour, now.minute, now.second)).total_seconds())
        print(listOfTimeDelays[i])
        i= i+1

# Note that you have to specify path to script
#This call runs the notification.

#Create a scheduler.
s = sched.scheduler(time.time, time.sleep)

#Takes a notification text and sends ends out the notification.
def notification(notify='failure to properly fill notification'):
    call(["node", "app.js", notify, "send this data"])

#test code. Mostly ignore this
def print_time(a='default'):
    print("From print_time", time.time(), a)


def send_notifications():
    #calculate all of the many times delays
    calculateMinutesIntoSeconds(testList, listOfTimeDelays)
    # calculateMinutesIntoSeconds(listOfTimesDay1, listOfTimeDelays)
    # calculateMinutesIntoSeconds(listOfTimesDay2, listOfTimeDelays)
    # calculateMinutesIntoSeconds(listOfTimesDay3, listOfTimeDelays)
    # calculateMinutesIntoSeconds(listOfTimesDay4, listOfTimeDelays)
    # calculateMinutesIntoSeconds(listOfTimesDay5, listOfTimeDelays)

    print("Time marker for beginning of study: ", time.time())
    #counter needed for calls
    i = 0
    #Just notify people that the study has started.
    s.enter(5, 1, notification, kwargs={'notify': 'Welcome to the Study!'})
    #This for loop fills the scheduler with every notification that needs to be sent.
    for member in listOfTimeDelays:
        #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, kwargs={'notify': listOfNotificationText[listOfNotificationNames[i]]})
        #Incriments the counter to make sure you get the next notification
        i = i+1
    #runs the scheduler
    s.run()
    #Marks the end of the study
    print("Time marker for end of study: ",time.time())

#Calls the above method
send_notifications()

更新：

嗯，在进一步检查，它看起来像喘息系统默认3.2，不会接受任何高于这一点的要求。看起来它接受“argument”，但正如Klaus所建议的，argument还需要notify与发送的通知位于同一区域。你知道吗

所以现在看起来

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

谢谢你的帮助。你知道吗

Answer 1

sched.Scheduler只接受kwargs参数from Python 3.3 onwards。我猜你在Debian机器上运行的是旧版本。你知道吗
