已安装Sass与Compass-sass，导入compass/css3报错求助

Hey there, let's troubleshoot that frustrating import error you're hitting with Compass and Sass. Here are actionable steps to get this sorted:

• Verify Compass-sass is properly installed and accessible
  First, double-check that the gem is actually installed and available in your environment. Run these commands in your terminal:

  gem list compass-sass
  compass version
  

  If compass version throws an error, it means Compass isn't properly set up—even if gem list shows it's installed. This usually happens if your gem path isn't correctly added to your system's PATH.

• Ensure you're running commands from the right directory
  Your config.rb looks correctly configured, but Compass needs to be run from the directory where this config file lives. If you're in your scss folder when you run compass watch or sass --watch, it won't pick up the config and won't know where to find Compass's modules. Navigate to the parent directory (where config.rb, scss, and css folders are all located) and try compiling again.

• Add an explicit require to config.rb
  Sometimes Compass needs a nudge to load its core modules. Add this line to the top of your config.rb:

  require 'compass'
  

  This ensures that Compass is initialized alongside Sass during compilation, so it can locate its css3 framework files.

• Check for file system inconsistencies
  On case-sensitive systems (like Linux or macOS), make sure your import statement matches the actual file path exactly. For example, if the folder is named CSS3 instead of css3, the import will fail. You can find the exact path of Compass's install directory with:

  gem which compass
  

  Navigate to that path and confirm the frameworks/compass/css3 folder exists.

• Reinstall your gems (last resort)
  If nothing else works, a corrupted installation might be the issue. Uninstall both gems and start fresh:

  gem uninstall compass-sass sass
  gem install compass-sass
  

  This ensures all dependencies are installed correctly and no files are missing or corrupted.
