Rails3和`cd somehwere &&做點什麼`

Question

我有一個rails項目，其下有其他項目，子項目有rake和bundler文件。

當我做紅寶石-e`CD子項目& & rake`，或紅寶石-e`CD子項目& & bundle`，命令按預期方式工作，並使用子項目耙/捆綁器文件。但是，當我從Rails3控制檯（rails 3.0.3）執行同樣的操作時，rake會給出錯誤無法加載這樣的文件 - 初始化程序，並且bundle的操作就好像它是從根目錄啓動的。

我嘗試了Rails2.3.10控制檯中的相同命令，它們按預期工作。 Rails3在這裏做錯了什麼？

我通過RVM使用Ruby 1.9.2。

bold_rewards ∴ ruby -v 
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.5.0] 
bold_rewards ∴ rake -T | wc -l 
     46 
bold_rewards ∴ cd vendor/plugins/pretty_flash 
pretty_flash ∴ rake -T | wc -l 
     6 
pretty_flash ∴ cd ../../.. 
bold_rewards ∴ rails c 
Loading development environment (Rails 3.0.3)

不幸的是，我認爲捆紮機是一個非常就難了：

increment ∴ cat Gemfile                                       
source 'http://rubygems.org' 

gem 'rails', '3.0.3' 

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

gem 'sqlite3-ruby', :require => 'sqlite3' 

# Use unicorn as the web server 
# gem 'unicorn' 

# Deploy with Capistrano 
# gem 'capistrano' 

# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+) 
# gem 'ruby-debug' 
# gem 'ruby-debug19' 

# Bundle the extra gems: 
# gem 'bj' 
# gem 'nokogiri' 
# gem 'sqlite3-ruby', :require => 'sqlite3' 
# gem 'aws-s3', :require => 'aws/s3' 

# Bundle gems for the local environment. Make sure to 
# put test-only gems in this group so their generators 
# and rake tasks are available in development mode: 
# group :development, :test do 
# gem 'webrat' 
# end 
increment ∴ cat vendor/subproject_x/Gemfile                                  
source 'http://rubygems.org' 

gem 'net-ssh' 

increment ∴ rails c
