ruby-on-rails - Postgresql:致命:用户 "rooms"的密码身份验证失败

Question

我刚刚在一台新计算机上安装了 Rails 和 postgresql(按照 this 教程)，我正在尝试运行之前制作的 Rails 应用程序，该应用程序正在运行并正在生产中。但是，当我尝试运行该应用程序时，我收到了此错误:

这是我的 database.yml 文件:

development:
    adapter: postgresql
    encoding: unicode
    host: localhost
    database: rooms_development
    pool: 5
    username: rooms
    password: rooms

我对 Rails 还很陌生，我不知道如何解决这个问题 - 请帮忙!

这是 Postgres 告诉你密码登录失败。 The manual advises:

Messages like this indicate that you contacted the server, and it is willing to talk to you, but not until you pass the authorization method specified in the pg_hba.conf file. Check the password you are providing, or check your Kerberos or ident software if the complaint mentions one of those authentication types.
