You have to require Bootstrap LESS (bootstrap_and_overrides.css.less) in your application.css
您必须在 application.css 中要求 Bootstrap LESS (bootstrap_and_overrides.css.less)
/*
*= require bootstrap_and_overrides
*/

I'm going to answer this noting that I am working on ruby 2 / rails 4 application (NOT rails 3)
我要回答这个问题，我正在研究 ruby 2 / rails 4 应用程序（不是 rails 3）
Requiring Bootstrap LESS (bootstrap_and_overrides.css.less) in your application.css is meaningless here, because the pipeline comes already with "require_tree ." which automatically includes everything inside the folders of the asset pipeline.
在 application.css 中要求 Bootstrap LESS (bootstrap_and_overrides.css.less) 在这里没有意义，因为管道已经带有“require_tree”。它会自动包含资产管道文件夹中的所有内容。
After pulling my hair for several hours, I found that removing the 3 required gems from the group :asset in the Gemfile is the only way to fix it
拉我的头发几个小时后，我发现从 Gemfile 中的组 :asset 中删除 3 个必需的宝石是修复它的唯一方法
So, Do Not do this in you Gemfile:
所以，不要在你的 Gemfile 中这样做：
group :assets do
gem "therubyracer"
gem "less-rails"
gem "twitter-bootstrap-rails"
end
And instead DO this:
而是这样做：
gem "therubyracer"
gem "less-rails"
gem "twitter-bootstrap-rails"

The Bootstrap gem comes with it's own bundled version of Bootstrap which it will take responsibility for importing. Don't import the Bootstrap gem in the :assets group, or the gem assets won't be found.
Bootstrap gem 带有它自己的 Bootstrap 捆绑版本，它将负责导入。不要在 :assets 组中导入 Bootstrap gem，否则将找不到 gem 资产。
Note that the assets group has been removed in Rails 4.
请注意，资产组已在 Rails 4 中删除。

I was using Bootstrap 2 and less on Rails 4.0.1. I decided to upgrade to Bootstrap 3 but "twitter-bootstrap-rails" is still on Bootstrap 2. There are a few gems available but I found the simplest approach was to add the css, js and fonts manually (followed these instructions Using bootstrap 3 with rails 4).
我在 Rails 4.0.1 上使用 Bootstrap 2 及以下版本。我决定升级到 Bootstrap 3，但“twitter-bootstrap-rails”仍在 Bootstrap 2 上。有一些 gems 可用，但我发现最简单的方法是手动添加 css、js 和字体（按照这些说明使用 bootstrap 3带导轨 4)。
Follow these instructions, ensure "therubyracer" and "less-rails" gems are installed and then a few more steps are required to get less working with bootstrap 3 and rails 4:
按照这些说明，确保安装了“therubyracer”和“less-rails” gems，然后需要更多的步骤来减少引导程序 3 和 rails 4 的工作：
- Download Bootstrap 3 source (Bootstrap source)
- Create directory "/vendor/assets/stylesheets/bootstrap"
- Copy contents of bootstrap source "less" directory (lots of less files) to "/vendor/assets/stylesheets/bootstrap"
Create "bootstrap_and_override.css.less" in "app/assets/stylesheets". Import "bootstrap.less" into "bootstrap_and_override.css.less", example of mine including a couple of test customisations:
@import "../../../vendor/assets/stylesheets/bootstrap/bootstrap.less"; @navbar-height: 120px; @body-bg: #F7911B;
- 下载 Bootstrap 3 源代码（Bootstrap 源代码）
- 创建目录“/vendor/assets/stylesheets/bootstrap”
- 将引导源“less”目录（大量文件）的内容复制到“/vendor/assets/stylesheets/bootstrap”
在“app/assets/stylesheets”中创建“bootstrap_and_override.css.less”。将“bootstrap.less”导入“bootstrap_and_override.css.less”，我的例子包括几个测试定制：
@import "../../../vendor/assets/stylesheets/bootstrap/bootstrap.less"; @navbar-height: 120px; @body-bg: #F7911B;
Hope this is useful to anyone wanting to try Bootstrap 3 with less.
希望这对任何想要以更少的价格尝试 Bootstrap 3 的人有用。

for me, less-railsgem was missing from Gemfile and adding it and running bundlesolved the issue.
对我来说，less-railsGemfile 中缺少 gem 并添加它并运行bundle解决了这个问题。

You might have missed to run
rails g bootstrap:install less
It worked like a charm
你可能错过了运行
rails g bootstrap:install less
它就像一个魅力
