我使用的是 Ruby1.9 和 Rails 2.3.4，并且安装了 mysql-ruby (2.8.1) gem.

I'm using Ruby1.9 and Rails 2.3.4 and I have mysql-ruby (2.8.1) gem installed.

当我尝试 rake db:create 我得到以下内容

when I try rake db:create I get the following

无法创建数据库{适配器"=>mysql"，数据库"=>war_development"，用户名"=>root"，密码"=>nil，主机"=>本地主机"}，字符集:utf8，整理:utf8_unicode_ci(如果你设置手动设置字符集，请确保您有一个匹配的排序规则)

Couldn't create database for {"adapter"=>"mysql", "database"=>"war_development", "username"=>"root", "password"=>nil, "host"=>"localhost"}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation)

我的database.yml有以下用于开发

My database.yml has the following for development

development: adapter: mysql database: war_development username: root password: host: localhost

知道出了什么问题吗?

谢谢，

推荐答案

root 用户可以不用密码吗?mysqlserver 是监听 127.0.0.1 还是本地主机?

Are you allowed to use the root user without password? Is the mysqlserver listening on 127.0.0.1 or localhost?
