Rails 4：守卫不是捆绑包的一部分。将其添加到 Gem 文件。 (Gem::加载错误)

Question

我正在尝试复制 Michael Hartl 的 Rails 教程中的 Advanced testing setup，该教程使用 guard-minitest.

这是我的 Gemfile:

source 'https://rubygems.org'

gem 'rails',        '4.2.2'
gem 'sass-rails',   '~> 5.0'
gem 'uglifier',     '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder',     '~> 2.0'
gem 'sdoc',         '~> 0.4.0', group: :doc

group :development, :test do
  gem 'sqlite3',     '1.3.10'
  gem 'byebug',      '6.0.2'
  gem 'web-console', '2.2.1'
  gem 'spring',      '1.3.6'
end

group :test do
  gem 'minitest-reporters', '1.0.20'
  gem 'mini_backtrace',     '0.1.3'
  gem 'guard-minitest',     '2.4.4'
end

group :production do
  gem 'pg',             '0.18.2'
  gem 'rails_12factor', '0.0.3'
end

这是我在运行 bundle install --without production:

Bundle updated!
Gems in the group production were not installed.

看来我确实安装了 guard-minitest 2.4.4。

但是，当我运行 bundle exec guard init 时，出现以下错误：

/Users/XXX/.rvm/gems/ruby-2.2.1@global/gems/bundler-1.10.4/lib/bundler/rubygems_integration.rb:292:in `block in replace_gem': guard is not part of the bundle. Add it to Gemfile. (Gem::LoadError)
    from /Users/XXX/.rvm/gems/ruby-2.2.1/bin/guard:22:in `<main>'
    from /Users/XXX/.rvm/gems/ruby-2.2.1/bin/ruby_executable_hooks:15:in `eval'
    from /Users/XXX/.rvm/gems/ruby-2.2.1/bin/ruby_executable_hooks:15:in `<main>'

知道我做错了什么吗？

Answer 1

如 guard-minitest README 的安装部分所述，gem 的更新版本也需要 guard。

我刚刚更新了我的 Gemfile 如下：

[...]
group :test do
  gem 'minitest-reporters', '1.0.20'
  gem 'mini_backtrace',     '0.1.3'
  gem 'guard'
  gem 'guard-minitest',     '2.4.4'
end
[...]

现在一切正常。
