Я установил эту проблему стирая это 3 пакета: «easy_install», «пип» и «virtualenv», а затем установить все с нуля.

Answer 2

получаю эту ошибку на Mavericks OS X.

Traceback (most recent call last): 
    File "/usr/local/bin/virtualenv-2.7", line 5, in <module> 
    from pkg_resources import load_entry_point 
    File "/Library/Python/2.7/site-packages/pkg_resources.py", line 2749, in <module> 
    working_set = WorkingSet._build_master() 
    File "/Library/Python/2.7/site-packages/pkg_resources.py", line 446, in _build_master 
    return cls._build_from_requirements(__requires__) 
    File "/Library/Python/2.7/site-packages/pkg_resources.py", line 459, in _build_from_requirements 
    dists = ws.resolve(reqs, Environment()) 
    File "/Library/Python/2.7/site-packages/pkg_resources.py", line 628, in resolve 
    raise DistributionNotFound(req) 

мне пришлось удалить предыдущую установку virtualenv. Поэтому я удалил следующий

sudo rm /usr/local/bin/virtualenv 
sudo rm /usr/local/bin/virtualenv-2.7 

Я нашел эти пути через которые команды и перегрузочного и мой bash_profile. Затем я удалил virtualenv через Pip.

sudo pip uninstall virtualenv 

Наконец-то я переустановил virtualenv через Pip.

sudo pip install virtualenv 

был тогда в состоянии получить вещи работать

У меня была такая же проблема, и нашел решение на группу Google. Кажется, что/usr/local/bin/virtualenv не обновлялось, поэтому, если вы его откроете, вы увидите ссылку на старый virtualenv 1.7.1.2, когда в вашей системе установлена ​​более новая версия.

Так что вам просто нужно открыть/USR/местные/бен/virtualenv и заменить его:

#!/usr/local/bin/python 
# -*- coding: utf-8 -*- 
import re 
import sys 
from virtualenv import main 

if __name__ == '__main__': 
sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0]) 
sys.exit(main()) 

И это делает трюк!
