我无法在heroku安装gunicorn whitenoise

Question

我正在尝试部署我的python-django website on heroku。我使用了以下命令

(firstproject) $ pip install dj-database-url gunicorn whitenoise

我犯了这样的错误

Requirement already satisfied (use --upgrade to upgrade): dj-database-url in /home/aparna/firstproject/lib/python3.4/site-packages
Requirement already satisfied (use --upgrade to upgrade): gunicorn in /home/aparna/firstproject/lib/python3.4/site-packages
