你需要安装 psycopg2 Python库。

安装

下载 http://initd.org/psycopg/ ，然后将其安装在Python PATH

下

下载后，轻松解压缩tarball：

  $ python setup.py install 
 

或者如果你愿意，请通过 easy_install 或 pip 。

^{（我更喜欢使用轻而易举的easy_install）。} >

• $ easy_install psycopg2


• $ pip安装psycopg2

配置

---

在设置 .py

  DATABASES = {
'default'：{
'ENGINE'：'django.db.backends.postgresql'，
'NAME'：'db_name'，
'USER '：'db_user'，
'PASSWORD'：'db_user_password'，
'HOST'：''，
'PORT'：'db_port_number'，
}

I'm new to Python and Django.

I'm configuring a Django project using PostgreSQL database engine backend, But I'm getting errors on each database operations, for example when i run manage.py syncdb, I'm getting:

C:\xampp\htdocs\djangodir>python manage.py syncdb
Traceback (most recent call last):

Can someone give me a clue on what is going on?

You need to install psycopg2 Python library.

Installation

---

Download http://initd.org/psycopg/, then install it under Python PATH

After downloading, easily extract the tarball and:

$ python setup.py install

Or if you wish, install it by either easy_install or pip.

^{(I prefer to use pip over easy_install for no reason.)}

• $ easy_install psycopg2
• $ pip install psycopg2

Configuration

---

in settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'db_name',                      
        'USER': 'db_user',
        'PASSWORD': 'db_user_password',
        'HOST': '',
        'PORT': 'db_port_number',
    }
}
