I managed to solve this problem by renaming my file from run.py to app.py But according to @saransh singh in the comments we can also solve it by making changes in the procfile from web: gunicorn app:run To web: gunicorn run:app我设法通过将我的文件从run.py重命名为app.py来解决这个问题但是根据评论中的@saransh singh，我们也可以通过从web: gunicorn app:run To web: gunicorn run:app
