使用罗盘进行编译时出错，找不到导入文件或文件不可读

当我运行罗盘编译时，我得到：

    error sass/styles.scss (Line 39 of sass/wh-base/_imports.scss: File to import not found or unreadable: components/productNavigation.
Load paths:
  Compass::SpriteImporter
  /var/www/web/styles/sass
  /usr/local/lib/ruby/gems/2.0.0/gems/compass-core-1.0.0.rc.1/stylesheets

  /usr/local/lib/ruby/gems/2.0.0/gems/breakpoint-2.4.6/stylesheets)
Compilation failed in 1 files.

这是我的“宝石清单信息”

我尝试了其他gem版本（最新版本），但没有任何结果。

我正在使用ruby 2.0.0

有什么帮助吗？
