我已经在 heroku 上部署了我的 flask 项目，但由于某种原因我收到了这个错误
Application error

Procfile.txt
web: gunicorn app:run
run.py是我的文件名，如下：-
from gumshuda import app
if __name__ == "__main__":
app.run(debug=True)
如有需要请询问更多信息。
我通过将我的文件从 run.py 重命名为 app.py 设法解决了这个问题
但根据评论中的@saransh singh
我们也可以通过更改 procfile 来解决它
来自 web: gunicorn app:run
至 web: gunicorn run:app
我已经在 heroku 上部署了我的 flask 项目，但由于某种原因我收到了这个错误

Procfile.txt
web: gunicorn app:run
run.py是我的文件名，如下：-
from gumshuda import app
if __name__ == "__main__":
app.run(debug=True)
如有需要请询问更多信息。
我通过将我的文件从 run.py 重命名为 app.py 设法解决了这个问题
但根据评论中的@saransh singh
我们也可以通过更改 procfile 来解决它
来自 web: gunicorn app:run
至 web: gunicorn run:app
