css - 如何将 stylesheet_link_tag 与 bootstrap-sprockets 一起使用？

Question

我想从 bootstrap-sass 加载 bootstrap-sprockets gem 在我的布局文件中(例如 application.html.erb )而不是在 application.scss 中。通常建议将 bootstrap 和 bootstrap-sprockets 放在 application.scss 中，如下所示:

@import "bootstrap-sprockets";
@import "bootstrap";

然后像这样加载到您的 application.scss 中:

  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>

我想像这样加载它们:

<%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag    'bootstrap-sprockets', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag    'bootstrap', 'data-turbolinks-track' => true %>

这样我就可以根据某些应用程序变量在 erb 中加载它们。例如使用 bootswatch 和一个实例变量:

<%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag    'bootstrap-sprockets', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag    'bootswatch/'+ @account.style.name.downcase + '/variables',  'data-turbolinks-track' => true %>
<%= stylesheet_link_tag    'bootstrap', 'data-turbolinks-track' => true %>

虽然，以这种方式加载这些 Assets 时，我一直收到 RoutingError，即使我在 assets.rb 中的预编译 Assets 中有它，就像这样 Rails。 application.config.assets.precompile += %w( bootstrap-sprockets )

如何让这些 Assets 从 gem 正确加载？

Answer 1

请检查您使用的文件扩展名可能是您使用的是 yourFileName.css 但链接转到了 yourFileName.scss 或 .sass

还要检查你的 Gemfile 是否有

gem 'bootstrap-sass'
