Djnago почему ошибка при запуске?

Question

[zkweb]

В джанго новичок.

1) В системе две версии Питона. 2.6 и 2.7
2) Создал окружение (virtualenvs) указав версию питона 2.7
3) всё окружение успешно установилось
4) без проблем в окружение добавил Djnago

Django.wsgi

#/usr/bin/python2.7
#coding: utf-8

import os
import sys

PROJECT_ROOT = os.path.dirname(__file__)
PYTHON_LIBS = '/home/adko/.virtualenvs/test/lib/python2.7/site-packages'

sys.path.extend((PROJECT_ROOT,PYTHON_LIBS,os.path.dirname(PROJECT_ROOT)))
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

В итоге такая ошибка:

[zkweb]

видно что он подтягивает версию питона 2.6 почему то

Answer 1

[sim3x]

2.6 в топку
непонятно зачем тебе изменять wsgi.py - продакшен настраивается через nginx-uWSGI
девелопмент сервер стартует ./manage.py runserver

Answer 2

[Станислав Фатеев]

не активируется виртуальное окружение, что-то настроили не правильно -djbook.ru/rel1.8/howto/deployment/wsgi/modwsgi.htm...

[Станислав Фатеев]

zkweb: это все потому, что продолжает использоваться python2.6 - то есть, либо virtualenv корявый, то ли он вообще не используется mod_wsgi

[Станислав Фатеев]

zkweb: вот это еще попробуйте - обратите внимание на python-path https://www.digitalocean.com/community/tutorials/h...

[zkweb]

Станислав Фатеев: а как вы определили что он использует 2.6?

[Станислав Фатеев]

zkweb: по fasttypes = {int, str, frozenset, type(None)} ^ SyntaxError: invalid syntax

[zkweb]

Станислав Фатеев: а можно где-то указать чтобы он использовать 2.7 ?

[Станислав Фатеев]

zkweb: короче я нагуглил - походу надо mod_wsgi пересобрать с поддержкой питона 2.7 https://code.google.com/p/modwsgi/wiki/Installatio... - я сам юзаю nginx+uwsgi, там попроще

Answer 3

[Владимир @]

создавай виртуальное окружение с нужной версией питона
virtualenv venv --no-site-packages --distribute -p /usr/bin/python2.7
и она будет там по умолчанию

[zkweb]

я так и сделал

[sim3x]

--no-site-packages
           Ignored (the default).  Don´t give access to the global
           site-packages modules to the virtual environment.
