PyMySQL Python 3 Django VirtualEnv MySQLdb

Question

所以昨天当我从我的主目录运行virtualenv时，我已经运行了。我现在已经多次遇到这个问题而没有明确的答案。我对此做了很多研究，但似乎没有黑白回答。今天我把我的virtualenv移到/usr/local/virtualenvs以更好地管理我的项目和中提琴，它又被打破了。 Error loading MySQLdb module: No module named 'MySQLdb'现在是我存在的祸根。这次我似乎无法修复它。我甚至尝试将我所做的重复复制到我的主目录中并遇到同样的问题。我没有从系统中删除任何包。我在virtualenv中安装了相同的软件包。此时我迷失了。我甚至写下了我从新安装中采取的步骤到达工作的virtualenv。我当然不想重新安装。请帮助：）

虚拟环境：

Ubuntu Server 16.04 LTS
python 3.5
django 1.10.2
pymysql 0.7.9

我的settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'auth',
        'USER': 'user',
        'PASSWORD': 'pass',
        'HOST': 'localhost',
        'PORT': '3306',
    },
    'cogs': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'cogs',
        'USER': 'user',
        'PASSWORD': 'pass',
        'HOST': 'localhost',
        'PORT': '3306',
    }
}

错误：

Traceback (most recent call last):

加

try:
    import pymysql
    pymysql.install_as_MySQLdb()
except ImportError:
    pass

到manage.py和wsgi.py

现在正在工作。
