我正在尝试修改我的虚拟环境以添加新库（django-cron）。当我执行PIP列表
时(env_dili_py27)[todd@somewhere site-packages]$ pip list
Django (1.5.4)
django-common-helpers (0.6.0)
django-cron (0.3.3)
django-filter (0.7)
djangorestframework (2.3.8)
Markdown (2.3.1)
MySQL-python (1.2.4)
pip (1.4.1)
setuptools (0.9.8)
South (0.8.4)
wsgiref (0.1.2)
但是，包装列表不包括djanago cron：

因此，它看起来像现在已经安装了。我唯一与之不同的是在...
上使用详细命令安装等等，我想我看到了一些东西。我正在使用python运行django，从：
/home/todd/envs/env_dili_py27/...
但是图书馆安装在
/home/todd/.virtualenvs/env_dili_py27/...
什么是 .virtualenvs 在目录路径中（我是Django/python和linux的新手）？
在列表顶部添加应用
installed_apps = [＃默认Django应用程序'django_crontab'，
其他应用
]
保存settings.py并运行服务器
