当我尝试在 python 环境中运行服务器时出现以下错误跟踪：

Traceback (most recent call last):
  File "/home/web/.virtualenvs/kolibri/bin/kolibri", line 5, in <module>
    from pkg_resources import load_entry_point

pkg_resources.DistributionNotFound: The 'django==1.9.1' distribution was not found and is required by kolibri

它与 django==1.9.1 相关。知道为什么会这样吗？？？

【问题讨论】：

它是一个操作系统。 kolibrios.org
那么它在这里做什么：/home/web/.virtualenvs/kolibri/bin/kolibri

标签： django python-2.7 django-models

【解决方案1】：

是的，找到 ans ，只需运行命令：

sudo pip install -U djangorestframework

或者您可以按照以下步骤操作：

* first check version of django
* if it is not given as per distrubution package then delete it using following command:
    $ pip uninstall Django
* again install specific version of django:
    $ pip install django==1.9.1  (e.g 1.9.6 or 1.8 or 1.7)
    $ django-admin --version  // 1.9.1
