我正在设置一个新的开发环境,遵循django安装教程并遇到问题。这是我尝试运行syncdb时得到的结果
Running `python doccal/manage.py syncdb` attached to terminal... up, run.1
Traceback (most recent call last):

Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
我在使用相同的步骤之前设置了同一个项目并且从未出现过问题。几个星期前,我收到了一封Heroku正在从共享数据库迁移出来的电子邮件,并假设这是以某种方式参与的。
另外,我注意到本教程中有两个新步骤,即安装dj-database-url并将这些行添加到settings.py
import dj_database_url
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}
我试图在有和没有这些行的情况下运行它,无论如何都会遇到同样的问题。
另一篇文章建议修复是这样做的
heroku addons:add shared-database
尝试过,收到一条消息,指出不推荐使用shared-database并使用heroku-postgresql,但这没有任何效果。
感谢您的帮助

将HOST配置为localhost,如:
'HOST': 'localhost',
