它被报告为 bootstrap-rails gem 的问题:https://github.com/anjlab/bootstrap-rails/issues/91

It is reported as an issue with the bootstrap-rails gem: https://github.com/anjlab/bootstrap-rails/issues/91

宝石

gem 'sass-rails', '>= 3.2' # sass-rails needs to be higher than 3.2
gem 'bootstrap-sass', '~> 3.1.1'

已安装(在assets组内外都尝试过)，application.css.scss包含

are installed (tried outside and inside of assets group), application.css.scss contains

@import "bootstrap";

仅.

当尝试 bundle exec rake assets:precompile 时，它给出了这个错误:

When attempting bundle exec rake assets:precompile it gives this error:

我检查了 /home/joe/.rbenv/versions/1.9.3-p448/lib/ruby/gems/1.9.1/gems/bootstrap-sass-3.1.1.0/vendor/assets/stylesheets/bootstrap.scss 实际上首先在 bootsrap/ 目录中导入了它下面的 _variables.scss 文件(在 _alerts.scss 等之前)，它确实......和_variables.scss 它定义了 $alert_padding.

I checked that /home/joe/.rbenv/versions/1.9.3-p448/lib/ruby/gems/1.9.1/gems/bootstrap-sass-3.1.1.0/vendor/assets/stylesheets/bootstrap.scss does actually import the _variables.scss file below it in the bootsrap/ directory first (prior to _alerts.scss etc), and it does... and in _variables.scss it defines $alert_padding.

在 environments/production.rb 文件中，我注释掉了有关资产的所有内容，并按照手册 尝试了 config.assets.initialize_on_precompile = truehttps://github.com/twbs/bootstrap-sass

In the environments/production.rb file I commented everything about assets out, and tried just config.assets.initialize_on_precompile = true in accordance with the manual https://github.com/twbs/bootstrap-sass

• 谷歌搜索

• https://github.com/twbs/bootstrap-sass
• https://github.com/anjlab/bootstrap-rails/issues/91
• railscast 328, 329 and 268 looking for clues
• googling about
• modifying gem's bootstrap/bootstrap.scss to use underscore and .scss, various tinkering such as commenting out lines relating to assets in environments/production.rb, commenting in only the one in the gem's page (manual) config.assets.initialize_on_precompile = true

我将 gem 的内容复制到我的资产目录中，这基本上就是 jlong​​ 的引导程序所做的.

I copied the gem's contents into my assets directory, which is essentially what jlong's bootstrap did.

它不看 application.css.scss...它忽略了我放在那里的内容，而是选择查看文件夹并加载这些文件.这就是它首先看到 alerts.scss 的原因.我尝试将 _variables.scss 的名称更改为 _aavariables.scss 无济于事

its not looking at application.css.scss... its ignoring what I put in there and electing to instead look into the folders and loading those files. Which is why it sees alerts.scss first. I tried changing the name of _variables.scss to _aavariables.scss to no avail

推荐答案

我的具体问题原来是一些代码隐藏在 application.rb...

My specific problem turned out to be some code hiding in application.rb...

我将 puts config.assets.precompile.inspect 添加到 config/environments/production.rb 并惊叹于它输出的正则表达式.然后我在代码库中搜索config.assets.precompile"，然后在 application.rb 中找到:

I added puts config.assets.precompile.inspect to config/environments/production.rb and marvelled at the regex it output. Then I searched the codebase for "config.assets.precompile" and lo, in application.rb, there was:

config.assets.precompile << /(^[^_/]|/[^_])[^/]*$/
...
config.assets.precompile += ["*.js", "*.css", "jquery-migrate-rails.js"]

导致问题的原因.(我有点困惑，因为我已经三重检查了这些正则表达式，他们不应该选择 _alerts.scss ......但让我们掩盖这一点并专注于删除这些行修复它的事实)

which was causing the problem. (I'm slightly puzzled as I've triple checked those regexes and they shouldn't be picking up _alerts.scss... but lets gloss over that and focus on the fact that removing those lines fixed it)

也许这会帮助其他人...

Maybe this will help someone else...
