搜索了高和低...发现了类似的问题，但没有任何修复有帮助...有没有人知道接下来要尝试什么？

我正在关注Railstutorial.org 5.1.2并在安装 bootstrap-sass gem 后，重新启动 apache 后得到以下信息：

已安装引导程序...（也尝试了 2.3.2.0 版）

bart:/var/www/sample_app$ bundle | grep bootstrap
Using bootstrap-sass (2.3.2.2)

和

bart:/var/www/sample_app$ bundle show bootstrap
/home/bart/.rvm/gems/ruby-2.0.0-p247@railstutorial_rails_4_0/gems/bootstrap-sass-2.3.2.2

将 gem bootstrap-sass 放入 Gemfile 中的 :asset 组已经解决了类似的问题 - 这没有帮助。（例如，几乎完全相同的东西）

group :assets do
  gem 'sass-rails', '4.0.0'
  gem 'uglifier', '2.1.1'
  gem 'coffee-rails', '4.0.0'
  gem 'bootstrap-sass', '2.3.2.0'
end

实际上，我刚刚在 Gemfile 中添加了 bcrypt-ruby-3.1.2 gem，这给出了同样的问题......

我跳过了第 3 章（全部 3.6）的结尾，那里有更多关于测试的内容，所以也许我在某个地方错过了一步，但那里的一切似乎都是可选的。

其他人提到做一个

rake gem

或 rake gemspec 但我得到了类似的东西：

bart:/var/www/sample_app$ bundle exec rake gemspec --trace
rake aborted!
Don't know how to build task 'gemspec'

并且还没有弄清楚这到底意味着什么。

解决了。

非常感谢所有建议——尝试它们帮助我继续推动不同的事业。

当rails s（在应用程序内部）产生良好的结果时，线索就出现了，但点击 apache 却没有。找到了我错过的Apache/Passenger 设置文档（RoR 的新手，所以实际上“不知道”）在虚拟主机配置中设置了 PassengerRuby。

根据教程，我创建了 gemset “railstutorial_rails_4_0”/home/bart/.rvm/wrappers/ruby-2.0.0-p247@railstutorial_rails_4_0

在 /etc/apache2/mods-available/passenger.conf

PassengerRoot /home/bart/.rvm/gems/ruby-2.0.0-p247/gems/passenger-4.0.19
PassengerDefaultRuby /home/bart/.rvm/wrappers/ruby-2.0.0-p247/ruby

bundle install在将东西放入教程 gemset之前，这很棒。

我在虚拟主机定义中错过了这个：

PassengerRuby /home/bart/.rvm/wrappers/ruby-2.0.0-p247@railstutorial_rails_4_0/ruby

重启阿帕奇。

现在它完美地工作了！

您已gem 'bootstrap-sass', '2.3.2.0'在 Gemfile 中指定，但在您的机器上加载了 2.3.2.2。尝试卸载 gem 并重新运行 bundle 命令。

bundle exec gem uninstall GEM_NAME
bundle install

不久前我也浏览了本教程。查看我的代码，我从未指定 bootstrap-sass 的版本。您可能也想尝试一下。
