apscheduler: LookupError: No trigger by the name "interval" was found

Originally reported by: Rodrigo Brim (Bitbucket: rodrigo_brim, GitHub: Unknown)


I’m getting this error with OSX 10.9.4. The following lines describes my problem. Sorry if this is a stupid post.


rbr:python rodrigo$ pip list | grep -i apscheduler
APScheduler (3.0.1)

rbr:python rodrigo$ cat ./schedule.py


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'))

    except (KeyboardInterrupt, SystemExit):

rbr:python rodrigo$ ./schedule.py 
Traceback (most recent call last):

Give the instantiated trigger as the second parameter to add_job(). See http://apscheduler.readthedocs.org/en/latest/modules/schedulers/base.html#apscheduler.schedulers.base.BaseScheduler.add_job for further details.
