当我尝试这个时，我收到了这个错误：
来源 ./env/bin/activate
sudo python manage.py syncdb
错误：没有名为 south 的模块
我在激活虚拟环境后安装了南，使用 pip install south（以及 django）。
在 settings.py 中安装的应用程序：
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：

psycopg2.OperationalError: FATAL: Peer authentication failed for user "django"
我使用这些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.
}
}
