Question

我修改了代码后发现它是错误的，现在我无法使用gunicorn来运行它。如果您从此处开始有关于结构化或分解的建议，也欢迎您。我正试图让它从5天开始运行，苦苦挣扎。

目录结构

app--
     --db.sqlite
     --__init__.py
     --models.py
     --MyFunctions.py
     --routes.py
     --schemas.py
     --sockets.py
app.py

内部app.py

from app import *


from app.MyFunctions import *
from app.models import *
from app.schemas import *
from app.routes import *
from app.sockets import *


port=os.environ.get("PORT")

if port is None or port == "":
    port = 3000

if __name__ == '__main__':
    socketio.run(app, host='0.0.0.0', port=port) # when running on heroku

在 init .py

内部

import jwt
from flask import (
    Flask,
    request,
    jsonify,
    make_response,
)
from flask_socketio import (
    SocketIO, 
    send, 
    emit, 
    join_room, 
    leave_room,
)
from sqlalchemy import (
    Column,
    Integer,
    String,
    Boolean,
    ForeignKey,
    DateTime,
    Sequence,
    Float,
)
from flask_sqlalchemy import SQLAlchemy
from flask_marshmallow import Marshmallow
from os import environ


def debug(msg):
    print('\n\n\n'+str(msg)+'\n\n\n'+'\n\nType:\t'+str(type(msg))+'\n\n')

from .models import *
socketio = SocketIO(app, cors_allowed_origins='*')

models.py内部（仅导入与模型相关的东西，我的大部分导入仅位于此处）

from flask import (
    Flask,
    request,
    jsonify,
    make_response,
    redirect,
)
from flask_socketio import (
    SocketIO, 
    send, 
    emit, 
    join_room, 
    leave_room,
)
from sqlalchemy import (
    Column,
    Integer,
    String,
    Boolean,
    ForeignKey,
    DateTime,
    Sequence,
    Float,
)
from flask_sqlalchemy import SQLAlchemy
from flask_marshmallow import Marshmallow
from flask_bcrypt import Bcrypt
from os import environ
from flask_cors import CORS, cross_origin



app = Flask(__name__)
root = os.path.dirname(os.path.abspath(__file__))
CORS(app, support_credentials=True)
basedir = os.path.abspath(os.path.dirname(__file__))

PG = os.environ.get("DATABASE_URL")

if PG is None or PG=="":
    app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + \
        os.path.join(basedir, 'db.sqlite')
else:
    app.config['SQLALCHEMY_DATABASE_URI'] = PG


app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
app.config['SECRET_KEY'] = environ.get('STRIPE_API_KEY')


db = SQLAlchemy(app)

ma = Marshmallow(app)

bcrypt = Bcrypt(app)

socketio = SocketIO(app, cors_allowed_origins='*')

编辑：目前，我仅使用python在heroku上运行该应用程序，因此我的Procfile看起来像

web: python app.py

是的，我尝试了许多其他格式，例如

web: gunicorn app:app
web: gunicorn models:app
web: gunicorn app/models:app

还尝试通过制作不同的运行文件和许多其他方法恐怕我需要更改其结构才能使其正常工作。

Answer 1

我重命名了app.py文件，然后它起作用了

内部Procfile

web: gunicorn gettingstarted.wsgi
web: gunicorn runner:app
