文档声明import_by_path在Django 1.6中是新的，而问题提到了Django 1.3.1。 也许你安装了两个版本？ 检查Python路径上的所有目录。

从Django 1.7中不推荐使用import_by_path
所以这实际上是因为检测到Django版本的方式存在错误：

    if django.get_version() >="1.7":
        from django.utils.module_loading import import_string
    else:
        from django.utils.module_loading import import_by_path as import_string

由于词法比较，不适用于Django> = 1.10。

需要编辑和分叉库或在本地环境中，您可以更改如下：

Edit site-packages/omnibus/management/commands/omnibusd.py

from django.utils.module_loading import import_string as import_by_path
