Question

我花了最后6个小时修复问题，例如修改$ PATH，安装Gems以最终得到应有的一切。但是在我用它的组件创建项目文件夹并尝试运行服务器之后，我得到了这样的消息： -

\KAMAL$ ls
Gemfile     README.rdoc app     config.ru   doc     log     script      tmp
Gemfile.lock    Rakefile    config      db      lib     public      test        vendor
\KAMAL$ rails server
=> Booting WEBrick
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting
/Library/Ruby/Gems/1.8/gems/mysql2-0.3.11/lib/mysql2/client.rb:44:in `connect': Access denied for user 'root'@'localhost' (using password: NO) (Mysql2::Error)
    from /Library/Ruby/Gems/1.8/gems/mysql2-0.3.11/lib/mysql2/client.rb:44:in `initialize'
    from /Library/Ruby/Gems/1.8/gems/activerecord-3.2.13/lib/active_record/connection_adapters/mysql2_adapter.rb:16:in `new'

“和上面的许多行一样”

此日志条目

Access denied for user 'root'@'localhost' (using password: NO) (Mysql2::Error)

显示您在localhost上使用root用户而没有密码作为数据库。 MySQL不认为这是一个有效的用户。以下行应发出相同的错误消息：

mysql -u root -h localhost

请检查db/database.yml文件

中的数据库用户/密码

Webrick Rails Server无法正常运行
