Welcome to Stackoverflow @vishnuvreddy欢迎来到 Stackoverflow @vishnuvreddy
Since you are deciding port using由于您决定使用端口
port = int(os.environ.get("PORT", 5000))
and mentioned --bind
in Procfile as below并在 Procfile 中提到
--bind
如下
web: gunicorn --bind 127.0.0.1:5000 wsgi:app
conflict each other.互相冲突。
Solution解决方案
Change Procfile to将 Procfile 更改为
web: gunicorn wsgi:app
