我有一个简单的Django应用程序，我正在尝试部署到Heroku。
我已按照将您的应用程序部署到Heroku 部分中列出的步骤进行操作：https://devcenter.heroku.com/articles/deploying-python。
我正在离开分支heroku。
当我执行git push heroku heroku:master时，第一次能够推送，一切都成功并且部署了应用程序，但是当我转到应用程序主页时，我收到503错误，表明favicon.ico不见了。然后我做任何小改动的提交，并再次尝试推送，我得到以下错误：

我尝试过的事情：
heroku run bash，并手动运行命令，同样的错误psycopg2添加到我的requirements.txt 在settings.py中修改和删除部分静态文件块，这是我目前所拥有的：
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'
# Extra places for collectstatic to find static files.
STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)
favicon.ico内有BASE_DIR/static。
这是我的requirements.txt：

任何人都能够了解我做错了什么？
答案 0 :(得分：0)
您的问题是错误输出中的这一行：
+=将django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: No module named psycopg2
添加到psycopg2。您的设置的其他一部分是设置Postgres数据库，您必须安装数据库驱动程序包才能使用。
