PyMySQL Python 3 Django VirtualEnv MySQLdb

Question

所以我昨天在我的主目录中运行 virtualenv 时运行了这个。我已经多次遇到这个问题，但没有明确的答案。我对此进行了很多研究，但似乎没有非黑即白的答案。今天我把我的 virtualenv 移到了/usr/local/virtualenvs 以更好地管理我的项目和中提琴，它又坏了。 Error loading MySQLdb module: No module named 'MySQLdb' 是我现在存在的祸根。这次我似乎无法修复它。我什至尝试将我所做的复制到我的主目录中并且遇到了同样的问题。我没有从我的系统中删除任何包。我在 virtualenv 中安装了相同的软件包。在这一点上，我迷路了。我什至写下了从全新安装到工作的 virtualenv 的步骤。我当然不想回到全新安装。请帮忙:)

虚拟环境：

Ubuntu Server 16.04 LTS
python 3.5
django 1.10.2
pymysql 0.7.9

我的设置.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):

提前致谢。

添加

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

致manage.py和wsgi.py

现在工作。
