Python django virtualenv-错误：没有名为south的模块

当我尝试以下操作时，会出现此错误：

source./env/bin/activate

sudo python manage.py syncdb

错误：没有名为south的模块

我在激活virtualenv后安装了south，使用pip安装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',

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.
    }

有什么问题吗

更新： 我在尝试不使用sudo进行同步时遇到此错误。可能与“南方”问题有关：

    'django.contrib.sessions',
    'django.contrib.sites',

    }

}

在安装south或运行syncdb时，不要成为sudoer。照办

pip install south python manage.py syncdb pip安装南部 python manage.py syncdb

---

只需从已安装的应用程序中删除south

Django 1.7及以上不需要南部

---

要删除south，请使用pip uninstall south然后使用y完全删除它

尝试将south放在已安装应用程序的末尾：现在您已经在系统范围内安装了south，您需要配置Django以使用它。这样做很简单；只需编辑settings.py并在已安装的应用程序末尾添加“south”。（）激活你的VirtualNV，启动python，然后从交互式shell中尝试“导入南方”。它有效吗？实际上我把它放在安装的应用程序的末尾。但它给出了相同的错误。我认为使用south path应该没问题，因为django和south在同一个目录中，django应用程序没有给出这个错误。@DanielEriksson是的，在interactive shell中它起作用了。所以我不明白为什么在interactive shell中看到south模块时会出现这个错误……通常我不使用sudo，但我认为它需要sudo，由于身份验证错误。我的坏：）对我来说，

south

不在已安装的应用程序中，但我仍然收到此错误。和

pip卸载south

报告：

south未安装
