当我试图在铁路中使用 Mysql 时发生错误
原标题:Getting an error when i try to use mysql in rails

我试图使用 Mysql 作为数据库 我的铁路应用程序。

这是我的数据库。yml 文件看起来像

development:
  adapter: mysql2
  encoding: utf8
  database: blog_development
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

这是当我尝试 rake db: create 命令时我所要犯的错误

hilarl@isa009:~/workspace/blog$ rake db:create rake aborted! Please install the mysql2 adapter: gem install activerecord-mysql2-adapter (mysql2 is not part of the bundle. Add it to Gemfile.)

任务: TOP gt; db: create (通过使用 -- trace 运行任务, 看到完整跟踪)

当我尝试 < code> gem 安装活动记录 Mysql2adapter I get EROR: 在任何仓库中找不到有效的宝石活动记录( & gt;= 0)

我正使用含有1.9.3p194的红宝石的乌本图和3.2.3铁轨。
