'django_postgrespool'不是可用的数据库后端 [英] 'django_postgrespool' isn't an available database backend

问题描述

在安装 django_postgrespool 并相应地配置我的项目后，我收到以下错误：

After installing django_postgrespool and configuring my project accordingly, I received the following error:

Traceback (most recent call last):
  File "C:\Users\Administrator\Documents\my_proj\my_module.py", line 14, in <module>
    from cortex.my_app.models import MyModel
  File "C:\Users\Administrator\Documents\my_proj\my_app\models.py", line 3, in <module>
    from django.db import models

    backend = load_backend(connection.settings_dict['ENGINE'])

    raise ImproperlyConfigured(error_msg)
django.core.exceptions.ImproperlyConfigured: 'django_postgrespool' isn't an available database backend.
Try using django.db.backends.XXX, where XXX is one of:
    'dummy', 'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'
Error was: cannot import name Diagnostics

当然我检查了我可以 import django_postgrespool 在同一个环境。

我发现这个类似的问题，但是它的解决方案是使用django 1.4+，我使用的是1.4.3

Of course I checked I can import django_postgrespool in the same env.
I found this similar issue, however its resolution was to use django 1.4+ and I'm using 1.4.3

推荐答案

卸载psycopg2- 2.5.1并安装 psycopg2-2.4.6 。

Uninstall psycopg2-2.5.1 and install psycopg2-2.4.6.

我不知道为什么它解决了这个问题，当psycopg2-2.5.1是最新的postgrespool的要求。我使用Windows Python 2.7.3 AMD64。
我已将将此作为错误报告给django-postgrespool

I don't know why it solves this problem, when psycopg2-2.5.1 is a requirement of the latest postgrespool. I am using Windows Python 2.7.3 AMD64. I've reported this as a bug to django-postgrespool
