psycopg2看不到我的PostgreSQL实例 [英] psycopg2 can't see my PostgreSQL instance

问题描述

我在Windows上，安装了32位python 2.6.6和psycopg2。

I'm on Windows, with a 32bit install of python 2.6.6 and psycopg2.

当psycopg2尝试连接时，它会得到 OperationalError ：

When psycopg2 tries to connect, it gets an OperationalError:

Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import psycopg2
>>> conn = psycopg2.connect("dbname=your_database user=postgres password=xxxx host=127.0.0.1:5432")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python26\lib\site-packages\psycopg2\__init__.py", line 164, in connect
    conn = _connect(dsn, connection_factory=connection_factory, async=async)
psycopg2.OperationalError: could not translate host name "127.0.0.1:5432" to address: Unknown server error

我能够使用 127.0.0.1:5432 上的pgAdmin3连接到PostgreSQL实例。

I am able to connect to PostgreSQL instance with pgAdmin3 on 127.0.0.1:5432.

有什么想法吗？

推荐答案

conn = psycopg2.connect("dbname=your_database user=postgres password=xxxx host=127.0.0.1 port=5432")
