我正在使用我的rails环境设置我的新Macbook（Lion OSX）并遇到一个奇怪的问题，我无法弄清楚问题是什么。
当我运行rake db：setup或rake db：migrate时，我收到以下错误：
rake aborted!
wrong number of arguments (1 for 0)
Tasks: TOP => db:migrate => environment
当我运行跟踪时，我得到以下内容：

如果我卸载0.9.2并运行一个运行rake 0.8.7的旧项目，则rake工作正常。所以我认为这是耙子的问题，但不完全确定？
有人有任何想法吗？
答案 0 :(得分：1)
问题似乎在于：
/Users/djforth/Websites/bdglobal/spec/factories/sites.rb:3:in `<top (required)>'
你错误地宣布了一家工厂，而且可能没有检查0.8.7。
