python - 为什么我的 python 代码出现内部服务器错误？

问题描述

我正在试验和开发一个 Flask 网页，它将使用 MySQL 数据库中的一些数据，经过一些编码后，我得到了内部服务器错误，我不知道为什么。

几天后我无法解决问题，我该怎么做才能让它工作？

我正在使用 Python3，托管的服务器是 Ubuntu 系统，我现在可以使用我通过 Hyper-V 托管的服务器 LAN 域（服务器名称）名称通过 LAN 访问该站点，因为我没有备用 PC为此，使用 Ubuntu。

奇怪的是，当我在笔记本电脑上本地测试它时，只有当我想连接托管在服务器虚拟机上的页面时，我才会收到 500 错误。

因为我不知道我将大部分文件上传到 GitHub 的问题出在哪里，所以这当然会被更改，后来出于安全原因删除，但现在更容易了。

这是来自 dbconnect.py 的代码

import mysql.connector

def connection_db():
    conn1 = connector.connect(host="localhost",
                                    user = "root",
                                    passwd = "pass",
                                    db = "db")
    c1 = conn1.cursor()
    return c1, conn1

解决方案

不要下载我将 content_management 误认为是 pip 模块的模块。你可以卸载模块pip uninstall contentful_management

出现错误是因为您在init .py 中导入模块。

尝试这个：

from name_of_the_parent_directory import content_management

你尝试使用

from . import content_management

name_of_the_parent_directory - 表示父目录，在您的 github 中它将是网页。
