ruby-on-rails - Bundler 不允许我安装 gems

Question

每当我尝试运行 rspec 测试时，我都试图消除这些烦人的 DEPRECATION WARNINGS(我正在通过 Rails 教程跋涉)。

我尝试遵循这里的建议:rspec triggers "DEPRECATION WARNING: The InstanceMethods module inside ActiveSupport::Concern will be no longer included automatically."简单地更新我的 rspec 版本。

但是，无论何时尝试，我都会得到这样的消息:

The bundle currently has rspec-core locked at 2.1.0.
Try running `bundle update rspec-core`

或者这个:

Bundler could not find compatible versions for gem "rspec-core":
  In Gemfile:
    rspec-rails (= 2.1.0) x86-mingw32 depends on
      rspec-core (~> 2.1.0) x86-mingw32

    rspec-core (2.10.1)

最后，我继续点击 bundle install 来更新我所有的 gem。然而，这产生了不更新那些 rspec 的美妙结果。这是怎么回事？ (而且我一直在更新我对当前 git 分支的提交。)

谢谢。

编辑:这是我的 gemfile 和 gemfile.lock 的样子:

source 'https://rubygems.org'

gem 'rails', '3.2.1'

group :development, :test do
    gem 'sqlite3', '1.3.5'
    gem 'rspec-rails', '2.1.0' #NOTICE: possible error with rails version
end

group :assets do
  gem 'sass-rails',   '~> 3.2.5'
  gem 'coffee-rails', '~> 3.2.2'    
  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.2'

group :test do
  gem 'capybara', '1.1.2'
end

group :production do
  gem 'pg', '0.12.2'
end

还有我的 gemfile.lock:

我认为您的问题在于您只需执行以下操作

sudo gem uninstall rspec-core -v 2.2.1
bundle update rspec-core

这对于其他依赖的 gem 可能是必需的，比如 (rspec-rails, rspec)

通过 gem list rspec 进行检查
