Haystack与Django 1.10不兼容？

Question

使用PIP和django version==1.10`安装django-haystack

Collecting django-haystack


Using cached django_haystack-2.5.0-py2-none-any.whl
Collecting Django<1.10 (from django-haystack)
  Using cached Django-1.9.9-py2.py3-none-any.whl
Installing collected packages: Django, django-haystack
  Found existing installation: Django 1.10
    Uninstalling Django-1.10:
Exception:
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/pip-8.1.2-py2.7.egg/pip/basecommand.py", line 215, in main
    status = self.run(options, args)
  File "/usr/local/lib/python2.7/dist-packages/pip-8.1.2-py2.7.egg/pip/commands/install.py", line 317, in run

    paths_to_remove.remove(auto_confirm)
  File "/usr/local/lib/python2.7/dist-packages/pip-8.1.2-py2.7.egg/pip/req/req_uninstall.py", line 115, in remove
    renames(path, new_path)
  File "/usr/local/lib/python2.7/dist-packages/pip-8.1.2-py2.7.egg/pip/utils/__init__.py", line 267, in renames
    shutil.move(old, new)
  File "/usr/lib/python2.7/shutil.py", line 303, in move
    os.unlink(src)
OSError: [Errno 13] Permission denied: '/usr/local/bin/django-admin'

为什么卸载django 1.10，甚至为什么它不能使用Ubuntu 16.04

如果这里有类似的问题或问题，请通知我，谢谢

你有没有试过用sudo安装它？通常需要使用sudo来安装一些依赖项
