APScheduler(Advance Python Scheduler) ImportError: No module named scheduler

Question

I am having following import error

"ImportError: No module named scheduler"

when I run the following python script:

"""
Demonstrates how to use the blocking scheduler to schedule a job that execute$
"""

from datetime import datetime
import os

from apscheduler.scheduler import BlockingScheduler


def tick():
 print('Tick! The time is: %s' % datetime.now())


if __name__ == '__main__':
 scheduler = BlockingScheduler()
 scheduler.add_job(tick, 'interval', seconds=3)
 print('Press Ctrl+{0} to exit'.format('Break' if os.name == 'nt' else 'C'$

try:
    scheduler.start()
except (KeyboardInterrupt, SystemExit):
    pass

I have installed APS scheduler using: sudo pip install apscheduler

I have also upgraded using: sudo pip install apscheduler --upgrade Also upgraded my system using "sudo apt-get install update && sudo apt-get upgrade"

Answer 1

I got same issue, but then I found,

I had installed apscheduler version 3 then I shifted to version 2.1.2 using,

pip uninstall apscheduler
pip install apscheduler==2.1.2

Just checkout before switching to version 2.1.2, If you wanted to use extra features added in version 3. In my case I didn't wanted much.
