使用 !global 变量标志编译 zurb 基础的 sass 错误

Question

'rake --trace assets:precompile' 命令给出以下错误：

rake aborted!
Sass::SyntaxError: Invalid CSS after "...ules: $modules ": expected "}", was "!global;"
  (in app/assets/stylesheets/foundation_and_overrides.scss:13)
foundation-rails-5.5.0.0/vendor/assets/stylesheets/foundation/_functions.scss:13
foundation-rails-5.5.0.0/vendor/assets/stylesheets/foundation/components/_global.scss:5
foundation-rails-5.5.0.0/vendor/assets/stylesheets/foundation/components/_grid.scss:5
foundation-rails-5.5.0.0/vendor/assets/stylesheets/foundation.scss:9
app/assets/stylesheets/foundation_and_overrides.scss:1327

错误似乎来自'foundation-rails-5.5.0.0/vendor/assets/stylesheets/foundation/_functions.scss'的第 13 行

  8 // IMPORT ONCE
  9 // We use this to prevent styles from being loaded multiple times for compenents that rely o    n other components.
 10 $modules: () !default;
 11 @mixin exports($name) {
 12   // Import from global scope
 13   $modules: $modules !global;
 14   // Check if a module is already on the list
 15   $module_index: index($modules, $name);
 16   @if (($module_index == null) or ($module_index == false)) {
 17     $modules: append($modules, $name) !global;
 18     @content;
 19   }
 20 }

SASS 语法对我来说看起来不错，如果我没有对生成的 'app/assets/stylesheets/foundation_and_overrides.scss 进行任何编辑，则编译不会出错。' 如果我对那个文件，比如下面这样，就会出现编译错误。

--- a/app/assets/stylesheets/foundation_and_overrides.scss

环境是 Rails 4.0.8，foundation-rails 5.5.0.0

Answer 1

foundation-rails gem 已将其 Sass 依赖项的下限设置为 >= 3.2.0，但使用的是 Sass 3.3 功能（!global 标志）。您需要为您的项目指定 3.3 的依赖项。

我还建议向 Foundation-rails 的维护者提交错误报告。
