Question

我使用 Windows 10 和 Python 3 在 Django 1.9.7 中使用网络应用程序我无法将应用程序连接到 MySQL 数据库。

我使用 MySQL 通过 PYMySQL <安装了与 cmd 建立连接的特定工具/ p>

使用pip install PYMySQL

输出

(bvc_env) C:\Users\Web\Desktop\PyDev\projects\bvc_env\src>pip install pymysql
Collecting pymysql
  Using cached PyMySQL-0.7.5-py2.py3-none-any.whl
Installing collected packages: pymysql
Successfully installed pymysql-0.7.5

以下是Settings.py

中的数据库选项

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'db_app',
        'HOST': 'host_app',
        'PORT': '3306',
        'USER': 'root',
        'PASSWORD': 'admin',
    }
}

然后我保存并开始使用此代码进行迁移：

(bvc_env) C:\Users\Web\Desktop\PyDev\projects\bvc_env\src>python manage.py migrate

我收到此错误

    import MySQLdb as Database

During handling of the above exception, another exception occurred:

    raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e)
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named 'MySQLdb'

但这引起了我的注意，我不知道如何解决这些问题

ImportError: No module named 'MySQLdb'或Error loading MySQLdb module: No module named 'MySQLdb'

问题更新费用

我尝试使用pip install mysql-python安装其他连接器，但它似乎不适用于Python 3

通过将pymysql导入您的manage.py file来获得我的解决方案，这是完整的代码。

#!/usr/bin/env python
import os
import sys
import pymysql

pymysql.install_as_MySQLdb()

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "bvc.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

运行manage.py migrate的Python不能与MySQL db一起使用
