Question

我几天来一直在努力解决这个问题 - 我在我的rails应用程序中添加了bootstrap（和其他一些宝石），但由于某种原因，相应的CSS文件没有呈现，因此引导样式没有显示出来

以下是我的文件的相关部分：

application.html.erb中的

app/views/layouts：

<head>
  <title>Myapp</title>
  <%= stylesheet_link_tag    "application", :media => "all" %>
  <%= javascript_include_tag "application" %>
  <%= csrf_meta_tags %>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
  <script type="text/javascript" src="https://raw.github.com/twitter/bootstrap/master/js/bootstrap-dropdown.js"></script>
</head>

application.css中的

app/assets/stylesheets：

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it's generally better to create a new file per style scope.
 *
 *= require_self
 *= require_tree .
 */

（此文件夹中还有更多CSS文件，包括bootstrap_and_overrides.css和gmaps4rails.css）。

实际在Chrome中呈现的源代码：

<head>
  <title>Myapp</title>
  <link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css" />
  <script src="/assets/application.js?body=1" type="text/javascript"></script>

  <script type="text/javascript" src="https://raw.github.com/twitter/bootstrap/master/js/bootstrap-dropdown.js"></script>
</head>

我的Gemfile：

gem "bootstrap-sass", '~> 2.3.0.1'
gem "simple_form"

gem 'gmaps4rails'

config/environments/development.rb：

config.cache_classes = false

# Log error messages when you accidentally call methods on nil.
config.whiny_nils = true

# Show full error reports and disable caching
config.consider_all_requests_local       = true
config.action_controller.perform_caching = false

# Don't care if the mailer can't send
config.action_mailer.raise_delivery_errors = false

# Print deprecation notices to the Rails logger
config.active_support.deprecation = :log

# Only use best-standards-support built into browsers
config.action_dispatch.best_standards_support = :builtin

# Raise exception on mass assignment protection for Active Record models
config.active_record.mass_assignment_sanitizer = :strict

# Log the query plan for queries taking more than this (works
# with SQLite, MySQL, and PostgreSQL)
config.active_record.auto_explain_threshold_in_seconds = 0.5

# Do not compress assets
config.assets.compress = false

# Expands the lines which load the assets
config.assets.debug = true

我将config/application.rb中的资产管道设置为true，并且我没有更改调试设置。我的RAILS_ENV是development。据我了解，由于boostrap_and_overrides.css.scss调用，rails应该编译并提供包括require_tree .在内的所有CSS文件。我多次运行rake assets:precompile和bundle exec rake assets:precompile，但我认为这不重要。我正在运行ruby 2.0.0p0（2013-02-24修订版39474）。

真正奇怪的是，我和我在这个项目上的合作伙伴拥有完全相同的代码（来自我们的github存储库），它可以在他们的本地机器上工作，但它对我的工作不起作用。有没有人对所发生的事情有任何意见？

我在Rails 3.2.6中也遇到了同样的问题，当我升级到Rails 3.2.15时它就消失了。
