Rails：帮助解决rake中止错误！
我一直在尝试运行rake db:migrate命令，但它无法正常工作。 我卸载并安装了gem，但没有运气。 我在某处读到了o.9不稳定，0.8.7没问题。 我试了但是我也有错误..
现在错误是
Fayimora-Femi-Baloguns-MacBook-Pro:sample_app fayimora$ bundle exec rake db:migrate /Library/Ruby/Gems/1.8/gems/bundler-1.0.15/lib/bundler/runtime.rb:136: warning: Insecure world writable dir /usr/local in PATH, mode 040777 /Library/Ruby/Gems/1.8/gems/bundler-1.0.15/lib/bundler/runtime.rb:136: warning: Insecure world writable dir /usr/local in PATH, mode 040777 (in /Users/fayimora/Sites/rails_projects/sample_app) DEPRECATION WARNING: config.generators in Rails::Railtie is deprecated.

Rakefile的内容
#!/usr/bin/env rake # Add your own tasks in files placed in lib/tasks ending in .rake, # for example lib/tasks/capistrano.rake, and they will automatically be available to Rake. # require 'rake/dsl_definition' require File.expand_path('../config/application', __FILE__) SampleApp::Application.load_tasks
请任何帮助都是明智的。 真的很难学习rails。
Rake 0.9.2的错误是固定的。 尝试使用Rake 0.9.2将其添加到Gemfile并运行
bundle update rake 。
除了试验或检查你的gem的兼容性之外，我不会使用Rails 3.1 RCs。 Rails 3.0.9非常稳定并得到广泛支持。

问题与gem不兼容Rails 3.1有关。 尝试从Gemfile中删除rspec， bundle install ，并运行rake任务。
