Python 继续获取模块NotFoundError:没有名为'；mainsite.settings'；将计划程序推送到heroku时

我正在尝试在heroku上设置一个调度程序-我在django文档上读到，我需要将django视为一个独立的应用程序

My

clock.py

，它触发后台作业，如下所示：

import os
import django
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mainsite.settings.dev')

django.setup()
from django.conf import settings
from apscheduler.schedulers.blocking import BlockingScheduler
from rq import Queue
from worker import conn
from accounts.tasks import print_message

q = Queue(connection=conn)

sched = BlockingScheduler()

@sched.scheduled_job('interval', minutes=3)
def timed_job():
    print('This job is run every three minutes.')
    q.enqueue(print_message, 'http://heroku.com') 


sched.start()

import os

import redis
from rq import Worker, Queue, Connection

listen = ['high', 'default', 'low']

redis_url = os.getenv('REDISTOGO_URL', 'redis://localhost:6379')

conn = redis.from_url(redis_url)

if __name__ == '__main__':
    with Connection(conn):
        worker = Worker(map(Queue, listen))
        worker.work()

我一直在说一个错误

ModuleNotFoundError:没有名为“mainsite.settings”的模块

即使我的文件夹结构甚至没有

mainsite.settings

。它存储在heroku服务器的

mainsite.settings.prod

和本地计算机上的

mainsite.settings.dev

中，如下所示：

我的

wsgi.py

如下所示：

import os
import django
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mainsite.settings.dev')

django.setup()
from django.conf import settings
from apscheduler.schedulers.blocking import BlockingScheduler
from rq import Queue
from worker import conn
from accounts.tasks import print_message

q = Queue(connection=conn)

sched = BlockingScheduler()

@sched.scheduled_job('interval', minutes=3)
def timed_job():
    print('This job is run every three minutes.')
    q.enqueue(print_message, 'http://heroku.com') 


sched.start()

import os

import redis
from rq import Worker, Queue, Connection

listen = ['high', 'default', 'low']

redis_url = os.getenv('REDISTOGO_URL', 'redis://localhost:6379')

conn = redis.from_url(redis_url)

if __name__ == '__main__':
    with Connection(conn):
        worker = Worker(map(Queue, listen))
        worker.work()

os.environ.setdefault（'DJANGO\u SETTINGS\u MODULE'，os.getenv（'DJANGO\u SETTINGS\u MODULE'））

如果有人想知道的话，

worker.py

文件如下所示：

import os
import django
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mainsite.settings.dev')

django.setup()
from django.conf import settings
from apscheduler.schedulers.blocking import BlockingScheduler
from rq import Queue
from worker import conn
from accounts.tasks import print_message

q = Queue(connection=conn)

sched = BlockingScheduler()

@sched.scheduled_job('interval', minutes=3)
def timed_job():
    print('This job is run every three minutes.')
    q.enqueue(print_message, 'http://heroku.com') 


sched.start()

import os

import redis
from rq import Worker, Queue, Connection

listen = ['high', 'default', 'low']

redis_url = os.getenv('REDISTOGO_URL', 'redis://localhost:6379')

conn = redis.from_url(redis_url)

if __name__ == '__main__':
    with Connection(conn):
        worker = Worker(map(Queue, listen))
        worker.work()

我做错了什么

我尝试了

echo$DJANGO\u设置\u模块

，它正确地显示了

mainsite.SETTINGS.dev

和Heroku

mainsite.SETTINGS.prod
