连接MySQL数据库后,Django无法运行

标签: python django database libreoffice assertions

当我进入时:

 python manage.py runserver

进入我的常用文件夹,我得到以下输出:

C:\Users\user\projects\steveone\steveone>python manage.py runserver Traceback (most recent call last):

我没有运行virtualenv(我知道),这只是在我今天通过JBDC将LibreOffice连接到MySQL后才开始发生的。从我收集的内容来看,我感觉它可能与路径有关,但我并不确定。我对网络开发还很陌生,但到目前为止,我已经能够找到我遇到的问题的答案。我昨天开始运行,这种情况只发生在我摆弄数据库之后。

编辑1:我已经尝试过重新安装anaconda的建议,但错误仍然存​​在。我得到了和以前一样的错误。

1 个答案:

答案 0 :(得分:1)

好的,经过几天和一些书呆子,我找到了解决方案。

我按顺序卸载了django,anaconda和python。

我按顺序重新安装了anaconda和django。

这使我的anaconda文件夹中的python.exe成为我的主要python应用程序。 (?)

然后我补充道:

  

C:\ Program Files \ MySQL \ MySQL Server 5.7 \ bin   进入我的系统环境变量路径。

在此之后我尝试用

运行应用程序
python manage.py runserver

但我得到了错误:

我尝试使用

pip install MySQL-python

但那是给了我

所以我首先尝试通过各种方法解决这个问题,但都失败了。 包括更新设置工具和滚轮:

pip install -U setuptools
pip install -U wheel

并运行msi安装程序:

  

MySQL的连接器的Python-2.1.7-py3.4 - 窗口x86-64位

失败(文档中描述的两种方式)。

所以我决定尝试通过Mysqlclient实现连接:

pip install mysqlclient 

修复了问题,现在应用运行了。

最后,我只能推测问题是什么,如果有人读到这些并且回想起来有一些想法,那么我很乐意听到它们。
