我已经在本地 django 服务器上安装了 django/postgres 并且工作正常。我正在尝试让 Apache 工作。我已经设置了 mod_wsgi 并且能够获得“Hello World”，并重新启动 Apache。我快到了，但是当我调出 localhost/index.html 时，我收到了这个服务器错误:
TemplateSyntaxError: Caught ImproperlyConfigured while rendering:
'django.db.backends.postgresql_psycopg2' isn't an available database
backend.

django.db.backends.XXX, where XXX is one of:

[Thu Sep 02 13:46:30 2010] [error] [client 127.0.0.1] Error was:

莫非mod_wsgi和psycopg版本不兼容？有没有人尝试过这种类型的设置？
更新 1:
我降级到 2.6、mod_wsgi、psycopg2，但在 apache 日志文件中仍然出现此错误。

你知道它可能表示什么吗？
更新 2:
原因在文件 django/db/backends/postgresql_psycopg2/base.py，版本 2.2.2，第 9 行: 从 django.db 导入工具
但我仍然不知道如何解决这个问题。 有一个文件 django/db/utils.py，所以它应该可以工作。毕竟，它适用于开发服务器。但不适用于 Apache + mod_wsgi
最佳答案
也许 this Ticket帮助你:
or whatever it is worth, I have confirmed that if I downgrade python to 2.6 and then likewise downgrade mod_wsgi and psycopg2, Django will work with Postgres on Apache as expected
关于python - django、postgres 8.4、psycopg 2.2.2、python 2.7、mod_wsgi，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3633099/
