運行「heroku本地」時工作進程中的異常

Question

我最近收購了一個項目，我正在使用heroku構建。我想在本地運行它，但是我遇到了麻煩，而且我對Heroku沒有太多經驗。這是我在嘗試運行heroku本地時所獲得的結果。

蘋果終端命令

kaMacintosh:zddev ka$ heroku local

Procfile

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

看來6號線是是mysql.connector問題，這裏是第幾行，以在main.py

主.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 

任何想法是什麼導致錯誤或如何解決。是真的mysql.connector導致main.py中第6行的問題？我正在使用Python 2.7.11。

運行在自己的gunicorn main:app產生

Answer 1

有與MySQL連接器的問題-python庫。它在我的項目中途被放棄，所以它被安裝在heroku實例上，但不在我的本地機器上。相反，我剛剛更換了該線路requirements.txt文件：

mysql-connector-python==2.0.4 

與

https://cdn.mysql.com/Downloads/Connector-Python/mysql-connector-python-2.0.4.tar.gz 

Answer 2

嘗試運行手動

「蟒蛇manage.py的runserver 0.0.0.0:5000」
