我正在尝试使用uwsgi将flask应用程序作为服务运行。但是出现错误：

  

uWSGI进程17078出现分段错误

这是我尝试过的：

manage.py

from flask_script import Manager
from flask_migrate import Migrate,MigrateCommand
from whatsapp_api import ms_crm_whatsapp,db

migrate = Migrate(ms_crm_whatsapp,db)
manager = Manager(ms_crm_whatsapp)
manager.add_command('db',MigrateCommand)

如果名称 =='主要”：        manager.run（）

database.py

from whatsapp_api import db
from sqlalchemy.dialects.postgresql import JSON

# print('db##############',db)
class TempTable(db.Model):
    # print('TempTable')
    __tablename__ = 'crm_user_chat_data'

    id = db.Column(db.Integer,primary_key=True)
    name = db.Column(db.String())
    case_type = db.Column(db.String())
    sub_type = db.Column(db.String())
    number = db.Column(db.String())
    description = db.Column(db.String())
    crm_customer_id = db.Column(db.String())
    title = db.Column(db.String())

    def __init__(self,name,case_type,number,description,sub_type,crm_customer_id,title):
        print('inside __init__')
        self.name = name
        self.case_type = case_type
        self.number = number
        self.description = description
        self.sub_type = sub_type
        self.crm_customer_id = crm_customer_id
        self.title = title

    def __repr__(self):
        print('__repr__',__repr__)
        return '<id {}>'.format(self.id)

whatsapp_api.py

from flask import flask,request,jsonify
import time
import requests
import json
import re
from nltk.chat.util import Chat,reflections
from flask_sqlalchemy import SQLAlchemy
import psycopg2
ms_crm_whatsapp = flask(__name__)
ms_crm_whatsapp.config["DEBUG"] = True
ms_crm_whatsapp.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
ms_crm_whatsapp.config["SQLALCHEMY_DATABASE_URI"] = 'postgresql://user:user_password@localhost:5432/db_name'
db = SQLAlchemy(ms_crm_whatsapp)
from database import TempTable
con = psycopg2.connect("host=localhost dbname=db_name user=user password=user_password")
cur = con.cursor()

@ms_crm_whatsapp.route('/',methods=['GET','POST'])
def home():
   return "<h1> Hello welcome to the world of flask"

ms_crm_whatsapp.run（host ='0.0.0.0'port = 3000）

我正在运行python3 manage.py之类的应用

wsgi.py

from whatsapp_api import ms_crm_whatsapp
if __name__ == "__main__":
ms_crm_whatsapp.run()

在终端中，我尝试过

 uwsgi --socket 0.0.0.0:3000 --protocol=http -w wsgi:ms_crm_whatsapp

在终端我得到：
