我使用的是Windows 10，Python 3.7.6。使用以下软件包：
# Name Version Build Channel
mysql-connector-c 6.1.11 he025d50_1002 conda-forge
mysqlclient 1.4.6 pypi_0 pypi
sqlalchemy 1.3.12 py37hfa6e2cd_0 conda-forge
sqlite 3.30.1 hfa6e2cd_0 conda-forge
sqlparse 0.3.0 py_0 conda-forge
django 3.0.2 py37_0 conda-forge
django-classy-settings 2.1.1 pypi_0 pypi
django-debug-toolbar 2.1 py_0 conda-forge
我正在使用具有以下设置的 MySQL 数据库。此数据库是使用我公司内的 IT 云数据服务创建的。我下载了SSL证书并将它们放在我的django项目中。
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'MyTestTVPVDb',
'USER': 'MyTestTVPVDb_so',
'PASSWORD': 'YYYYYYYYYYYYYYYYYYY',
'HOST': 'XXXXXXXXXXXXXXXXXXXXXXX',
'PORT': '3307',
'OPTIONS': {
'ssl': {
'ssl-ca': os.path.join(SSL_CERT_ROOT, 'ca_cert.pem'),
}
}
}
}
现在，当我键入python manage.py dbshell时，我能够连接到DB OK，一切看起来都很好。我可以看到数据库支持 SSL。

但是，当我键入python manage.py runserver来启动服务器时，我收到以下异常，我不知道如何解决。

如果我将mysqlclient包从 v1.4.6 降级到 v1.3.14，服务器启动正常。

任何想法这里出了什么问题？是SSL证书有问题吗？
我通过将MariaDB从v10.0切换到v10.0 ->v10.2来解决此问题。看起来mysqlclient v1.4.6不能很好地与MariaDB v10.0配合
