我正在为Ruby on Rails开发设置Win7机器，并且似乎遇到了我的rake任务的问题。当我调用rake db：创建cmd窗口时，非常很长时间并转储以下内容：
C:\my\directory\rails>rake db:create --trace
(in C:/my/directory/rails)
** Invoke db:create (first_time)
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:create
foo already exists
foo already exists
C:/Ruby192/bin/rake: [BUG] Segmentation fault
