compass watch error - Mac OS X

Question

I've been running sass and compass for a few months now and yesterday I was having some problems with ruby and an unrelated project. So in the end I re-installed ruby and sass.

Since then I can no longer run compass watch without getting the error below.

None of the other compass commands seem to be working either, so I reinstalled compass and I still get the same error.

Here are the versions of ruby and sass I am running. compass -v doesn't work.

ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin11.4.2] Sass 3.3.0.alpha.253 (Bleeding Edge)

Does anyone have any ideas how I can fix this please?

Answer 1

It looks like you might have a version of SASS that doesn't work with this version of Compass

I found the answer here: https://github.com/chriseppstein/compass/issues/1514

The following worked for me:

Look at the version of SASS you have installed (you said Sass 3.3.0.alpha.253)

sass --version

Uninstall sass:

sudo gem uninstall sass

Reinstall sass - you should get the latest working version:

sudo gem install sass

Reinstall Compass (I did this and it kept my working version of SASS):

sudo gem install compass
