启动调度器出现 TypeError: unsupported type for timedelta minutes component: NoneType

[dta0502]

我在服务器部署过程中，进行到启动调度器这步： python scheduler_booter.py --usage validator

就会出现如下错误：

Traceback (most recent call last): File "scheduler_booter.py", line 22, in scheduler_start() File "/usr/local/lib/python3.5/dist-packages/click/core.py", line 722, in call return self.main(args, kwargs) File "/usr/local/lib/python3.5/dist-packages/click/core.py", line 697, in main rv = self.invoke(ctx) File "/usr/local/lib/python3.5/dist-packages/click/core.py", line 895, in invoke return ctx.invoke(self.callback, ctx.params) File "/usr/local/lib/python3.5/dist-packages/click/core.py", line 535, in invoke return callback(args, kwargs) File "/home/tding/haipproxy-0.1-v2/scheduler/scheduler.py", line 187, in scheduler_start scheduler.schedule_with_delay() File "/home/tding/haipproxy-0.1-v2/scheduler/scheduler.py", line 66, in schedule_with_delay schedule.every(internal).minutes.do(self.schedule_task_with_lock, task) File "/usr/local/lib/python3.5/dist-packages/schedule/init.py", line 393, in do self._schedule_next_run() File "/usr/local/lib/python3.5/dist-packages/schedule/init.py", line 428, in _schedule_next_run self.period = datetime.timedelta({self.unit: interval}) TypeError: unsupported type for timedelta minutes component: NoneType
