python – django virtualenv – 错误：没有名为south的模块

source ./env/bin/activate

sudo python manage.py syncdb

Error: No module named south

我在激活虚拟环境后安装南,使用pip install south(以及django).

在settings.py中安装了应用：

INSTALLED_APPS = (
    'south','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.sites','django.contrib.messages','django.contrib.staticfiles',

可能是什么问题呢？

更新：
尝试在没有sudo的情况下同步时出现此错误.也许它与“南方”问题有关：

(env)andrius @ ubuntu：?/ djcode / myproject $python manage.py syncdb

psycopg2.OperationalError: FATAL:  Peer authentication failed for user "django"

我使用以下命令为数据库创建了数据库和用户：

template1=# create database finance;
CREATE DATABASE
template1=# grant all privileges on database finance to django;
ERROR:  role "django" does not exist
template1=# create user django with password 'mydb123';
CREATE ROLE
template1=# grant all privileges on database finance to django;
GRANT
template1=# q

我在settings.py中的数据库设置：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',# Add 'postgresql_psycopg2','mysql','sqlite3' or 'oracle'.
        'NAME': 'finance',# Or path to database file if using sqlite3.
        'USER': 'django',# Not used with sqlite3.
        'PASSWORD': 'mydb123',# Not used with sqlite3.
        'HOST': '',# Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',# Set to empty string for default. Not used with sqlite3.
    }
