Heroku 应用程序在部署后立即崩溃

Question

我是运行我的应用程序的单个时钟测功机，但它在成功构建后立即崩溃。
错误信息-

Build succeeded
heroku[clock.1]: State changed from up to crashed
heroku[clock.1]: State changed from crashed to starting
heroku[clock.1]: Starting process with command `python3 clock.py`
heroku[clock.1]: State changed from starting to up
heroku[clock.1]: Process exited with status 0
heroku[clock.1]: State changed from up to crashed

然后错误再次重复。

clock.py-

from apscheduler.schedulers.blocking import BlockingScheduler   
sched = BlockingScheduler(timezone="UTC")
def job_1(): 
    print("Reached Here") 
sched.add_job(job_1,trigger='interval', seconds=150)

Procfile -

clock: python3 clock.py

Answer 1

你应该更正你的Procfile

clock: python clock.py

Heroku 默认使用 3.9.6，但您可以根据需要更改它（参见 Specifying Python version）

Answer 2

忘记包含 sched.start()
