I've solved this issue by downgrading the compass version. then i've tryed to understand what was the error. So the problem was version conflicts between sass 3.2.14 and 3.3.4 . compass 0.12.3 depends on 3.2.14 sass verison. Have a look at this link Can't get sass + compass + susy installed due to version conflict
If you want to make things work with the latest compass version. you can uninstall all sass and compass version that you have. then look for the appropriate version between them. This will things work perfectly. And as a better solution you can work with this : http://bundler.io/ .
Kind regards.
