Hi, I'm getting Sass::SyntaxError: File to import not found or unreadable: compass. while compiling my theme developed in 6.1 version of liferay. Any idea how to remove this. I have checked extra.css file. In this using import we are by default calling compass. I thought import is a part of css but I think not after getting this error.
Please explain me what kind of error is this and how to resolve this. Is any library needs to imported for this.

Complete error is:-

Any idea?

what version of tomcat are you using?

I'm using Tomact 7 bundled with liferay 6.1. In the past also, I have setup many times liferay individually and ran but I never had such experience. Is it because of some incompatibility?

(Sorry for posting whole long console output here. It is something very weird and I didn't want others to miss anything)

You should try using the latest 6.1 GA2 release instead of 6.1 GA1.

Unfortunately that little hint bought it's own nasty surprises...web site disappeared with some kind of theme issue

Someone else has the same issue:

Unfortunately for me, none of the hacks other have tried are working for me.

Make sure you also upgrade your plugins sdk. I was using an older version and it generated some random theme issues.

It turns out to be a little deeper. Following the upgrade steps as meticulously as I can results in deletion of all file data (from 'data' path), all users and roles being either deleted or unlinked (although curiously the organisation is still there), the deletion or unlinking of all content from the site, and the deletion or unlinking of all pages.

Deleting the site and installing a new Liferay site would have been a lot quicker, less painful and had pretty much the same result. Of course there is the minor issue of 'no content' outstanding from this process. :\

As far as I can tell, this '7Cogs' thing seem to really mess things up too. It should really be optional.
