import - Rails4 : @import "my_folder" (with index. css.sass 在里面)不再工作，只有 @import "my_folder/index"可以

Question

我们正在将 Rails 3.2 应用程序升级到 Rails 4.0。

我们有一个 assets/stylesheets/application/index.css.sass加载一些其他 sass 文件的文件，例如 assets/stylesheets/layout/index.css.sass文件。

在 Rails 3.2 中，它只需要做 @import "layout" ，但在 Rails 4.0 中，我们得到以下错误:

Sass::SyntaxError at /users/sign_in
File to import not found or unreadable: layout.

当明确做 @import "layout/index" ， 有用。

我的问题:

1) 为什么 @import "layout"在 Rails 4.0 中不再工作了？

2) 所有这些在哪里做 CompassRails::SpriteImporter路径从何而来？他们还好吗，或者有什么问题吗？

Answer 1

您应该可以 @import 'layout/*'加载文件夹中的所有文件。

如果使用 config.assets.paths << "#{Gem.loaded_specs['gemname'].full_gem_path}/app/assets/stylesheets/gemname" 无法正确解析路径，您也可以手动配置一些路径。 .然后，您将能够从 Assets 管道中包含它们。

希望能帮助到你!
