Django和oracle TypeError:环境只能包含字符串

我有一个项目需要连接到oracle数据库

当我使用sqlite3时，默认情况下它会带来以下字符串：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.oracle',
        'NAME': 'DBARS_PROD',
        'USER': 'userhere',
        'PASSWORD': 'passhere',


        }
}

应用程序可以正常工作，但当我使用以下字符串与oracle连接时：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.oracle',
        'NAME': 'DBARS_PROD',
        'USER': 'userhere',
        'PASSWORD': 'passhere',


        }
}

Django给了我以下错误：

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)

似乎当django查询oracle时，它返回的是unicode而不是字符串。或者有人知道该怎么做吗？

我已经找到了解决方案，显然是驱动程序cx_oracle在其最新版本6.0b1中。。。我遇到了连接问题，我只是再次降级到5.2，一切正常
