引发配置不当的psycopg2(postgresql)
引发配置不当的psycopg2(postgresql)
提问于 2015-09-26 07:11:52
我对django很陌生。我试图用我的项目配置postgresql。我遵循的步骤：
1) sudo apt-获取安装psycopg2
2)改变settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'dbname',
'USER': 'postgres',
'PASSWORD': 'postgres',
'HOST': '',
'PORT': '',
}
}3)运行python manage.py生成
但我错了

During handling of the above exception, another exception occurred:

当我遇到这个问题时，尽管包已经安装好了，它还是帮助我重新安装了它。不知道为什么。
