Question

我不确定我是怎么来到这里的，但是无论何时我运行guard init，它似乎都有点过分，而不是一次添加coffeescript / sass / livereload，它会做每一个好几次。

以下是运行guard init后我在命令行上获得的内容：

这是我Guardfile的内容：

# A sample Guardfile
# More info at https://github.com/guard/guard#readme

guard 'coffeescript', :input => 'app/assets/javascripts'

guard 'coffeescript', :input => 'app/assets/javascripts'

guard 'coffeescript', :input => 'app/assets/javascripts'

guard 'compass' do
  watch('^src/(.*)\.s[ac]ss')
end

# This will concatenate the javascript files specified in :files to public/js/all.js
guard :concat, type: "js", files: %w(), input_dir: "public/js", output: "public/js/all"

guard :concat, type: "css", files: %w(), input_dir: "public/css", output: "public/css/all"

guard 'livereload' do
  watch(%r{app/views/.+\.(erb|haml|slim)$})
  watch(%r{app/helpers/.+\.rb})
  watch(%r{public/.+\.(css|js|html)})
  watch(%r{config/locales/.+\.yml})
  # Rails Assets Pipeline
  watch(%r{(app|vendor)(/assets/\w+/(.+\.(css|js|html))).*}) { |m| "/assets/#{m[3]}" }
end

guard 'livereload' do
  watch(%r{app/views/.+\.(erb|haml|slim)$})
  watch(%r{app/helpers/.+\.rb})
  watch(%r{public/.+\.(css|js|html)})
  watch(%r{config/locales/.+\.yml})
  # Rails Assets Pipeline
  watch(%r{(app|vendor)(/assets/\w+/(.+\.(css|js|html))).*}) { |m| "/assets/#{m[3]}" }
end

guard 'livereload' do
  watch(%r{app/views/.+\.(erb|haml|slim)$})
  watch(%r{app/helpers/.+\.rb})
  watch(%r{public/.+\.(css|js|html)})
  watch(%r{config/locales/.+\.yml})
  # Rails Assets Pipeline
  watch(%r{(app|vendor)(/assets/\w+/(.+\.(css|js|html))).*}) { |m| "/assets/#{m[3]}" }
end

guard 'phpunit', :cli => '--colors' do
  watch(%r{^.+Test\.php$})
end

guard 'sass', :input => 'sass', :output => 'css'

guard 'sass', :input => 'sass', :output => 'css'

guard 'sass', :input => 'sass', :output => 'css'

guard 'sass', :input => 'sass', :output => 'css'

guard 'sass', :input => 'sass', :output => 'css'

guard 'uglify', :destination_file => "public/javascripts/application.js" do
  watch (%r{app/assets/javascripts/application.js})
end

显然我可以进去删除重复的行，但我想知道为什么它首先发生。

看起来Guard会在运行init时使用插件的所有可用版本 - 不确定它是否在实际运行时执行此操作（这会令人担心）。我遇到了同样的麻烦并检查了我的宝石清单：

gem list | grep guard

这向我展示了我安装了多少版本的防护相关插件：

guard (1.8.2, 1.8.0, 1.7.0, 1.6.2, 1.6.1, 1.5.4, 1.0.3, 1.0.1)
guard-concat (0.0.3)
guard-rspec (3.0.0, 2.5.3, 2.4.1, 2.3.3, 2.1.2, 1.2.1, 0.7.2, 0.7.0)
guard-sass (1.3.2)
guard-spork (0.8.0)
guard-uglify (0.1.0)
terminal-notifier-guard (1.5.3)

在重复排序的防护插件上运行gem清理：

gem cleanup guard-rspec

gem list | grep guard

然后显示：

guard (1.8.2, 1.8.0, 1.7.0, 1.6.2, 1.6.1, 1.5.4, 1.0.3, 1.0.1)
guard-concat (0.0.3)
guard-rspec (3.0.0)
guard-sass (1.3.2)
guard-spork (0.8.0)
guard-uglify (0.1.0)
terminal-notifier-guard (1.5.3)

现在我运行guard init时，我的Guardfile中没有重复的代码。

运行保护初始化复制观察者行
