连接 MySQL 数据库后，Django 不会 运行
Django won't run after connecting MySQL database
当我输入：
python manage.py runserver
进入我常用的文件夹，我得到以下输出：

我不是 运行 virtualenv（我知道），这只是在我今天通过 JBDC 将 LibreOffice 连接到 MySQL 之后才开始发生的。从我收集到的信息来看，我觉得这可能与路径有关，但我不太确定。我对网络开发还很陌生，但到目前为止，我已经能够找到我所面临问题的答案。我昨天搞定了 运行，这只是在我摆弄数据库之后才发生的。
编辑 1：我已经尝试了重新安装 anaconda 的建议，但错误仍然存在。我得到了和以前一样的错误。
好的，经过几天的苦思冥想，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。 (?)
然后我补充说：
C:\Program Files\MySQL\MySQL Server 5.7\bin
into my Path in system environment variables.
在此之后，我尝试 运行 使用
的应用程序
python manage.py runserver
但我得到了错误：

所以我首先尝试通过各种方法修复它，但都失败了。
包括更新设置工具和方向盘：
pip install -U setuptools
pip install -U wheel
和运行安装 msi 安装程序：
mysql-connector-python-2.1.7-py3.4-windows-x86-64bit
哪个失败了（文档中描述的两种方式）。
所以我决定尝试通过Mysqlclient来实现连接：
pip install mysqlclient
这解决了问题，现在应用 运行s。
最后，我只能推测问题出在哪里，如果有人读到这篇文章并回顾起来有一些想法，那么我很想听听他们的意见。
当我输入：
python manage.py runserver

Did you install mysqlclient or MySQL-python?
我试过使用
pip install MySQL-python
但这给了我

所以我首先尝试通过各种方法修复它，但都失败了。 包括更新设置工具和方向盘：
pip install -U setuptools
pip install -U wheel
和运行安装 msi 安装程序：
mysql-connector-python-2.1.7-py3.4-windows-x86-64bit
哪个失败了（文档中描述的两种方式）。
所以我决定尝试通过Mysqlclient来实现连接：
pip install mysqlclient
这解决了问题，现在应用 运行s。
最后，我只能推测问题出在哪里，如果有人读到这篇文章并回顾起来有一些想法，那么我很想听听他们的意见。
