【参考方案1】：

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

【参考方案2】：

import_by_path 已从 Django 1.7 中弃用 所以这实际上是因为检测 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您的本地环境中您可以更改如下：

编辑站点包/omnibus/management/commands/omnibusd.py

from django.utils.module_loading import import_string as import_by_path
