Question

我尝试使用本教程将我的数据库从sqlite3更改为postgresql：

https://tutorial-extensions.djangogirls.org/en/optional_postgresql_installation/

但是当我尝试迁移时，我收到以下错误

Traceback (most recent call last):
  File "c:\Users\gudat\Documents\Arbeit\Szenario\Python\venv1\lib\site-packages\
django\db\backends\base\base.py", line 213, in ensure_connection
    self.connect()
  File "c:\Users\gudat\Documents\Arbeit\Szenario\Python\venv1\lib\site-packages\

    self.connection = self.get_new_connection(conn_params)
  File "c:\Users\gudat\Documents\Arbeit\Szenario\Python\venv1\lib\site-packages\

    connection = Database.connect(**conn_params)
  File "c:\Users\gudat\Documents\Arbeit\Szenario\Python\venv1\lib\site-packages\
psycopg2\__init__.py", line 130, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
psycopg2.OperationalError

The above exception was the direct cause of the following exception:

django.db.utils.OperationalError

在我的settings.py

中

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'dbase',
        'USER': 'name',
        'PASSWORD': 'test',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

（是的，我更改了名称）使用Python 3.6.3和psycopg2（2.7.4）。

我做错了什么？

从sqlite3转换为postgresql
