耙错误：堆栈层次过深

我知道这是一个常见的问题，但我刚开始一个项目与新的Rails 3.1.0和Ruby 1.9.2 P290耙错误：堆栈层次过深

我第一次迁徙我已经有这个错误我不知道为什么。

我也去掉了宝石和重新tyring与DB：重置源“http://rubygems.org”

gem 'rails', '3.1.0' 

# Bundle edge Rails instead: 
# gem 'rails',  :git => 'git://github.com/rails/rails.git' 

gem 'sqlite3' 

#gem "rspec-rails", :group => [:test, :development] 

group :test do 
    #gem "factory_girl_rails" 
    #gem "capybara" 
    #gem "guard-rspec" 
    #gem "spork", "> 0.9.0.rc" 
    #gem "guard-spork" 
end

耙命令与bundle exec工作，但它会很高兴避免使用它。

非常感谢您提供提示和答案。

你捆绑的耙和你的系统耙有区别吗？我建议这就是问题所在。 'rake --version'和'bundle exec rake --version'。它看起来像试图再次需要rake库，并导致某种循环。 –

感谢马修，但我得到了相同的版本： 'Aurelien-Schlumbergers-MacBook-Pro：tchinchine Aurelien $ rake --version rake，0.9.2版本 Aurelien-Schlumbergers-MacBook-Pro：tchinchine Aurelien $ bundle exec rake --version rake，0.9.2版本 ' –

嗯......如果你尝试创建一个新的gemset，然后捆绑安装，并尝试再次耙取？是否有一些疯狂的宝石覆盖全球？ 'rvm gemset create tchinchine && rvm gemset use tchinchine'否则，我想不出为什么'bundle exec rake'会与'rake'有所不同 –

您应该在您的Gemfile中特别添加Rake版本> = 0.9.2！某些Rails 3版本存在一个错误，当您使用较旧的Rake版本时，会看到类似这样的奇怪错误。

在你的Gemfile：

gem 'rake' , '>= 0.9.2'

我会还建议你专门创建一个新的宝石为您的应用程序，例如

rvm gemset create yourproject 
rvm gemset use yourproject

或：

rvm gemset use yourproject --default

新宝石，你可能要加上“创业板安装耙”手动，然后运行“包安装”

除了使用单独的宝石使用你的Gemfile是让你的项目中的宝石版本保持稳定并与其他项目分离的最佳方式。
