在使用 django.db 模型在拨号计划中使用一些 python 脚本运行 freeswitch 时，我遇到了一个问题。每当它启动时，它都会导致错误：

freeswitch@ubuntu> 2013-08-15 06:56:08.094348 [ERR] mod_python.c:231 Error importing module
2013-08-15 06:56:08.094348 [ERR] mod_python.c:164 Python Error by calling script   "fs_scripts.ringback": <type 'exceptions.IOError'>

编辑：导致错误的行是从 django.db 的简单导入：
从 django.db 导入模型

整个设置已经在我无法访问的某些服务器上运行，因此 django 应用程序或脚本似乎没有问题......

任何帮助将不胜感激，因为我已经没有如何解决这个问题的想法了......

我不知道您的性能和可扩展性要求，尽管软交换机有实时要求来运行 rtp 流和信令。所以在 mod_python 下运行 django 应用程序并不是一个好的解决方案。此外，这与直接 python 解释器不同，某些东西不起作用。您可以在此处查看 mod_python 问题： mod_python 问题

我建议您将您的 python 解决方案拆分为客户端/服务器架构。在 mod_python 下运行的脚本将对您的 Django 应用程序进行查询。这样，您将摆脱 Freeswitch 方面的复杂性，获得可扩展性，提高性能，并且很可能使一切正常。
