error: Не удалось найти vcvarsall.bat при установке psycopg2 в windows7

Question

Im, использующий Windows 7 для разработки Django 1.3.7 с использованием PostgreSQL 9.3 в качестве базы данных. На моем settings.py я поставил DATABASE_ENGINE = 'django.db.backends.postgresql_psycopg2', но когда я пытаюсь выполнить python manage.py syncdb я получил эту ошибку:

C:\Django-Proj\myproj\myproj>python manage.py syncdb

Кто-нибудь есть идея о мое дело? заранее спасибо

Answer 1

Существует огромный список неофициальных бинарных файлов Windows для пакетов расширения Python, которые чрезвычайно полезны для пользователей Windows.

http://www.lfd.uci.edu/~gohlke/pythonlibs/#psycopg

Перейти к ссылке, скачать и установить его, и вы хорошо идти.

Cheers!

Answer 2

Не пытайтесь скомпилировать psycopg2 для Windows. Вам понадобится установка Visual Studio или Windows SDK и всевозможные беспорядки.

Просто возьмите двоичный файл: http://initd.org/psycopg/download/
