Procfile

web: gunicorn main:app --log-file=-

看来第6行是mysql.connector的问题,这里是main.py的前几行

main.py

import os
import sys
import json
import urllib
import custom
import mysql.connector
import datetime
import operator

from flask import Flask,jsonify
from flask import render_template
from flask import request,redirect,url_for
from mysql.connector import errorcode
application = Flask(__name__)
app = application

关于导致错误或如何解决的任何想法.它真的是mysql.connector导致main.py中第6行的问题吗？我使用的是Python 2.7.11.

运行gunicorn主：app自己生产
