Ruby on rails Rails 3.1.1测试：Ruby 1.9.3上的基准测试

我正在尝试使用raketest:benchmark与Rails 3.1.1和Ruby 1.9.3进行测试

我已经尝试过最新的rake版本：gem'rake'，“~>0.9.3.beta.1” 官方和建议的ruby prof gem:gem'ruby prof'，：git=>'https://github.com/wycats/ruby-prof.git"

但我总是犯这样的错误：

rake test:benchmark

这在我的ubuntu服务器和windows开发环境中都会发生。有什么想法吗

更新：我安装了RVM并使用ruby 1.9.2进行了尝试：它可以工作。在其他条件不变的情况下，切换到1.9.3会出现错误。这可能是ruby 1.9.3或rails/rake等中的一个bug。

您是否尝试过使用

bundle exec运行

$ bundle exec rake test:benchmark

您需要安装测试单元Gem。参见
谢谢你的建议，我试过了，但最终结果是一样的。我也试着用RVM来使用1.9.2，其他的都一样，它是有效的。谢谢你，我会在有机会的时候试试这个。
