【问题描述】：

没有找到任何解决方案。我在尝试启动 Rails 服务器时收到 require: cannot load such file -- guard/guard (LoadError) 错误。

ruby -v
ruby 2.1.2p95 (2014-05-08) [x86_64-linux-gnu]

rails -v
Rails 4.2.0

gem -v
2.2.2

这是我的 gem 文件：

[...]
group :development, :test do
  gem "pry-rails"

  # Guard
  gem 'guard-rspec'
  gem 'guard-spinach'

  # Testing
  gem 'minitest'
  gem 'turn'
  gem 'capybara'
  gem 'rspec-rails'
  gem 'spinach-rails'
  gem 'libnotify'
  gem 'awesome_print'

  # Spring bindings
  gem 'spring'
  gem 'spring-commands-rspec'
  gem 'spring-commands-spinach'
end
[...]

并且运行开发服务器不起作用：

rails server

    from bin/rails:4:in `<main>'

不过，当我注释掉 #gem 'guard-spinach' 时，它可以正常工作。

我已经使用 bundle install --path vendor/bundle 安装了我的 gems

这个没有简单的答案。

我想出了一些版本设置。可能，这不是最好的，但它有效。

group :development, :test do
  gem 'pry-rails'

  # Guard
  gem 'guard', '~> 2.2.4'
  gem 'guard-rspec', '~> 4.2.0'
  gem 'guard-spinach', '~> 0.0.2'
  gem 'rspec-rails', '~> 2.99'
  gem 'spinach-rails', '~> 0.2.1'

  # Testing
  gem 'minitest'
  gem 'turn'
  gem 'capybara'
  gem 'libnotify'
  gem 'awesome_print'

  # Spring bindings
  gem 'spring'
  gem 'spring-commands-rspec'
  gem 'spring-commands-spinach'
end
