【问题描述】:
当我运行 python manage.py syncdb 时,我得到这个错误:
OperationalError: could not translate host name "localhost" to address: nodename nor servname provided, or not known
我的 settings.py 文件如下所示:
if "IS_STAGING" in os.environ or "IS_PRODUCTION" in os.environ:
import dj_database_url
DATABASES = {'default':dj_database_url.config(default='postgres://localhost')}
else:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'test', # Or path to database file if using sqlite3.
# The following settings are not used with sqlite3:
'USER': 'test',
'PASSWORD': 'test',
'HOST': 'localhost', # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
'PORT': '', # Set to empty string for default.
}
}
【问题讨论】:
-
你的 /etc/hosts 中是否定义了 localhost?
-
'nslookup localhost' 在你的机器中返回什么?
-
您尝试只输入 127.0.0.1 还是将该行留空?
-
glasslion, localhost 在我的 etc/hosts.txt 文件中定义为:127.0.0.1 localhost
-
nslookup localhost' 返回:服务器:128.32.136.9 地址:128.32.136.9#53 ** 服务器找不到本地主机:NXDOMAIN
