我通过Ruby on Rails教程（Michael Hartl）学习RoR。
现在我尝试用Guard运行测试。
我的Gemfile：
source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0
gem 'rails', '4.0.2'
group :development, :test do
gem 'sqlite3', '1.3.8'
gem 'rspec-rails', '2.13.1'
gem 'guard-rspec', '2.5.0'
end
group :test do
gem 'selenium-webdriver', '2.35.1'
gem 'capybara', '2.1.0'
gem 'libnotify', '0.8.0'
end
gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'
group :doc do
gem 'sdoc', '0.3.20', require: false
end
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
我的警卫档案：
require 'active_support/inflector'
guard 'rspec', all_after_pass: false do
watch('config/routes.rb')
# Custom Rails Tutorial specs
watch(%r{^app/controllers/(.+)_(controller)\.rb$}) do |m|
["spec/routing/#{m[1]}_routing_spec.rb",
"spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb",
"spec/acceptance/#{m[1]}_spec.rb",
(m[1][/_pages/] ? "spec/requests/#{m[1]}_spec.rb" :
"spec/requests/#{m[1].singularize}_pages_spec.rb")]
end
watch(%r{^app/views/(.+)/}) do |m|
(m[1][/_pages/] ? "spec/requests/#{m[1]}_spec.rb" :
"spec/requests/#{m[1].singularize}_pages_spec.rb")
end
watch(%r{^app/controllers/sessions_controller\.rb$}) do |m|
"spec/requests/authentication_pages_spec.rb"
end
end
当我尝试跑步时：后卫（或捆绑执行警卫队）我得到了错误：

顺便说一句：
gem list | grep guard
guard (2.11.1)
guard-compat (1.2.1)
guard-rspec (2.5.0)
出了什么问题？
答案 0 :(得分：13)
这个错误花费了更多时间，我找到了真正的方法
$ cd <appfolder>
$ vim Gemfile
instead of
gem 'guard-rspec', '2.5.0'
replace on
gem 'guard-rspec', '4.6.0'
instead of
gem 'rspec-rails', '2.13.1'
replace on
gem 'rspec-rails', '3.3.2'
并且
$ bundle update
$ bundle exec guard init rspec
Guardfile是正确的。
答案 1 :(得分：3)
我遇到了同样的问题并最终得出结论，我的宝石版本中的某些依赖项阻止了我的guard-rspec gem更新到最新版本（4.5.0），而核心防护gem更新为2.12.5。一旦我解决了让我的版本的guard-rspec无法推进的问题，一切都突然就好了。
尝试编辑Gemfile并从中删除所有修复版本（不要删除gem行，只删除版本参数），Rails gem条目除外（保留4.0.2）。然后运行bundle update，看看是否能解决您的问题。
答案 2 :(得分：0)
我也跑过m.Hartl并遇到了这样的问题：
在guard init rspec之后出现错误：
16:31:39 - ERROR - Could not load 'guard/rspec' or '~/.guard/templates/rspec' or find class Guard::Rspec
16:31:39 - ERROR - Error is: No such file or directory - /home/andrey/.guard/templates/rspec
由于我是新手，我花了很多时间来解决这个问题。
据我所知，问题在于rspec 2.13和guard-rspec不兼容，后者需要rspec 2.14或更高版本。
所以最后我只是让bundle update来更新我的宝石。不知道将来它会不会给我带来任何问题，但现在它有效！）
答案 3 :(得分：0)
您可以按照@Igor的说法更新以下内容
$ cd <appfolder>
$ vim Gemfile
代替
gem 'guard-rspec', '2.5.0'
替换
gem 'guard-rspec', '4.6.0'
代替
gem 'rspec-rails', '2.13.1'
替换
gem 'rspec-rails', '3.3.2'
但是，运行rspec时会遇到问题。
所以也要更新以下版本。
代替
gem 'capybara', '2.1.0'
替换为
gem 'capybara', '~> 2.2'
