【中文标题】<function check_errors.<locals>.wrapper at 0x03A69780> 启动的线程中未处理的异常【英文标题】:Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x03A69780> 【发布时间】:2019-02-18 05:40:28 【问题描述】:

我目前正在学习 Python 课程并学习如何使用 Django。我刚刚创建了 mysite,目前正在尝试测试 Django 服务器。

我在cmd中运行了下面的命令,输出如下。

C:\Users\Win10\Desktop\Python\Newsite\mysite>python manage.py runserver

Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x03A69780>

希望我能在这方面得到建议,谢谢! :(

【问题讨论】:

@VineethSai 实际上没有编码任何东西。你说的可能重复是什么意思? 【参考方案1】:

看来您需要更新 Django 版本。看Here。

尝试删除现有版本的 django,

pip uninstall Django

然后使用重新安装

pip install Django==1.11.17

希望这能解决问题。

【讨论】:

我在网上找到了一个解决方案,它说 pip install django==1.11.17 它对我有用!但是,我想知道将来是否会出现任何并发症。谢谢! 不,不会有任何并发​​症。虽然使用 2.x 版本会更好,因为 django 在 python 2.x 生命周期结束后将停止对 1.x 版本的支持。那将是 2020 年左右。这是路线图djangoproject.com/weblog/2015/jun/25/roadmap 啊好吧。非常感谢!刚刚看到你在上面的更新。祝你有美好的一天。
