django.db.utils.OperationalError: could not connect to server: Connection refused
	Is the server running on host "127.0.0.1" and accepting
	TCP/IP connections on port 5432?

我的settings.py是

my settings.py is

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'elfmsdb',
        'USER': 'postgres',
        'PASSWORD': '',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}

我还检查了postgresql.conf，它使用5432作为端口.

i also checked the postgresql.conf and it is using 5432 as port.

另一个奇怪的是，我不小心在我的virtualenv之外运行了server，它正常工作，但Django版本是1.6.

another odd thing is that i accidentally runserver outside my virtualenv and it worked but the django version is 1.6.

请帮助我，非常感谢！

推荐答案

也许您可以尝试以下方法:

may be you can try with this:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'elfmsdb',
        'USER': 'postgres',
        'PASSWORD': '',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}
