尝试安装gem设备时出错,安装停止在gem bcrypt-ruby上:

$ gem install bcrypt-ruby
Error installing bcrypt-ruby:
ERROR: Failed to build gem native extension.

我在RVM下使用Ruby运行OSX 10.6.7.我重新安装了最新版本的xcode并重新安装了Ruby 64bit,Rails和所有宝石.

我试图运行rake db:为mysql数据库创建,但得到错误

$ rake db:create
rake aborted!
undefined method `task' for #<Sharebox::Application:0x0000010085a010>

我运行--trace并获取信息

这是我的database.yml文件

development:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: sharebox_development
  pool: 5
  username: root
  password:
  host: localhost

我重新安装ruby,rails和mysql但仍然得到相同的错误任何帮助将不胜感激.干杯
