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

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.


Your import is wrong. It should be:

from apscheduler.schedulers.blocking import BlockingScheduler

Reference example here:

"""
Demonstrates how to use the blocking scheduler to schedule a job that executes on 3 second
intervals.
"""

from datetime import datetime
import os

from apscheduler.schedulers.blocking 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
