ruby-on-rails - rails bootstrap-sass Assets 编译错误 - undefined variable 警报填充

Question

所有的道路都指向 bootstrap-sass

推荐链:

railscast-328(twitter bootstrap 基础)指的是

http://www.sitepoint.com/twitter-bootstrap-less-and-sass-understanding-your-options-for-rails-3-1/指的是

https://github.com/jlong/sass-bootstrap这反过来又惊呼有一个新的官方 bootstrap 端口可以在

上进行 sass。

https://github.com/twbs/bootstrap-sass这是 twitter-bootstrap 文章中的另一个选项

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

我相信我安装正确

gem

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 组外部和内部尝试)，application.css.scss 包含

@import "bootstrap";

只要。

但它给了我一个错误

尝试时 bundle exec rake assets:precompile它给出了这个错误:

rake aborted!
Undefined variable: "$alert-padding".

我查了一下 /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实际上在 bootsrap/ 中导入了它下面的 _variables.scss 文件目录第一(在 _alerts.scss 等之前)，它确实......并且在 _variables.scss 中它定义了 $alert_padding。

我怀疑我遗漏了一些明显的东西

在 environments/production.rb我将有关 Assets 的所有内容都注释掉了，然后只尝试了 config.assets.initialize_on_precompile = true按照说明书 https://github.com/twbs/bootstrap-sass
研究至今

railscast 328、329和268寻找线索

谷歌搜索

修改 gem 的 bootstrap/bootstrap.scss 以使用下划线和 .scss，各种修补，例如注释掉与 environments/production.rb 中的 Assets 相关的行，仅在 gem 页面(手册)中的一个中发表评论 config.assets.initialize_on_precompile = true

确定的问题

我将 gem 的内容复制到我的 Assets 目录中，这基本上就是 jlong​​ 的 bootstrap 所做的。

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

Answer 1

我的具体问题原来是一些隐藏在 application.rb 中的代码。 ...

我是怎么找到的

我加了 puts config.assets.precompile.inspect至 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了“config.assets.precompile”，在 application.rb 中，有:

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

这导致了问题。 (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)

也许这会帮助别人......
