我正在尝试使用 rails 3+ 设置 psql。我已经关注了这个http://railscasts.com/episodes/342-migrating-to-postgresql并且一切正常。我的 database.yml 有这个:
# PostgreSQL. Versions 8.2 and up are supported.
#
# Install the pg driver:
# gem install pg
# On Mac OS X with macports:
# gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config
# On Windows:
# gem install pg
# Choose the win32 build.
# Install PostgreSQL and put its /bin directory on your path.
#
# Configure Using Gemfile
# gem 'pg'
#
development:
adapter: postgresql
encoding: unicode
database: app_development
pool: 5
username: root
password:
host: localhost
port: 5432
# Connect on a TCP socket. Omitted by default since the client uses a
# domain socket that doesn't need configuration. Windows does not have
# domain sockets, so uncomment these lines.
#host: localhost
#port: 5432
# Schema search path. The server defaults to $user,public
#schema_search_path: myapp,sharedapp,public
# Minimum log levels, in increasing order:
# debug5, debug4, debug3, debug2, debug1,
# log, notice, warning, error, fatal, and panic
# The server defaults to notice.
#min_messages: warning
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: postgresql
encoding: unicode
database: app_test
pool: 5
username: root
password:
host: localhost
port: 5432
production:
adapter: postgresql
encoding: unicode
database: app_production
pool: 5
username: root
password:
host: localhost
port: 5432
当我运行'psql -U root -h localhost -p 5432 -W'时,无论我给它什么密码,它都无法连接。'rake db:create:all'也失败了
Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "database"=>"app_production", "pool"=>5, "username"=>"root", "password"=>nil}
有任何想法吗?
