Ruby on Rails Tutorial第三章關于bundle exec respec 版本的debug Ruby on Rails Tutorial 教程中--第三章的第一個測試 最後運作 $ bundle exec rspec spec/requests/static_pages_spec.rb時會因為版本的問題導緻一些列的出錯與教程中的結果會有不符debug比較繁瑣。在這裡總結一下我碰到的問題及其解決方案：
系統：ubuntu 13.04
ruby版本：ruby 2.0.0p481 (2014-05-08 revision 45883) [i686-linux]
Rails版本：Rails 4.1.4
第一種情況：沒在正确目錄下運作，報錯如下：
[email protected]:~/ror/sample /spec$ bundle exec rspec spec/requests/static_pages_spec.rb
/home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `load': cannot load such file -- /home/czl/ror/sample/spec/spec/requests/static_pages_spec.rb (LoadError)
from /home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `block in load_spec_files'
from /home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `each'

from /home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/runner.rb:80:in `run'
from /home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/runner.rb:17:in `block in autorun'
注意藍色字型那是錯誤目錄;cd 到spec/的父目錄運作就會成功;紅字為錯誤名稱
第二章情況： 配置檔案出錯
[email protected]:~/ror/sample$ bundle exec rspec spec/requests/static_pages_spec.rb
/home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `load': /home/czl/ror/sample/spec/requests/ static_pages_spec.rb:29: syntax error, unexpected keyword_end, expecting end-of-input (SyntaxError)
from /home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `block in load_spec_files'
from /home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `each'
from /home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `load_spec_files'

from /home/czl/.rvm/gems/ruby-2.0.0-p481/gems/rspec-core-2.13.1/lib/rspec/core/runner.rb:17:in `block in autorun'
請用vi 打開static_pages_spec.rb 在其29行出錯，改了就行;
第三種情況：版本問題
[email protected]:~/ror/sample$ bundle exec rspec spec/requests/static_pages_spec.rb
Warning: you should require 'minitest/autorun' instead.
Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'

其實已經能正常運作，錯誤的原因在于 Rails4.1.4版本問題屬于bug，解決方案：
[email protected]:~/ror/sample$ vi Gemfile
source ' https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.4'
gem 'minitest'
# Use sqlite3 as the database for Active Record
group :development, :test do
gem 'sqlite3', '1.3.8'
gem 'rspec-rails', '2.13.1'
end
group :test do
gem 'selenium-webdriver', '2.35.1'
gem 'capybara', '2.1.0'
end
在此處添加藍色字型，儲存後運作bundle install即可
[email protected]:~/ror/sample$ bundle install
。。。此處省略
最後
[email protected]:~/ror/sample$ bundle exec rspec spec/requests/static_pages_spec.rb

沒有報錯，成功。
如有其他問題可能是Rails配置問題，請添加相應的包處理，如：postgresql（即pg的問題），可以更新一下試試，然後$rails new 'project name'重新開始。其他請翻牆google
