I have installed the latest versions of compass, sass and susy. But still I am getting this error:

Unable to activate susy-2.1.1, because sass-3.2.17 conflicts with sass (~> 3.3.0)

Anyone knows how this Ruby thing works?

This is the list of my installed gems:

*** LOCAL GEMS ***

CFPropertyList (2.2.0)
chunky_png (1.3.0)
compass (0.12.4)
compass-core (1.0.0.alpha.19)
compass-import-once (1.0.4)
compass-rails (1.1.3)
fssm (0.2.10)
libxml-ruby (2.6.0)
multi_json (1.9.2)
nokogiri (1.5.6)

  • I'm not a Ruby dev, but it sounds like you need to uninstall sass 3.2.17. – Zoey Mertes Mar 22 '14 at 10:04
  • Sounds logical. I'll try installing a previous version – Remi Mar 22 '14 at 10:05
  • No luck:( Tried the bundler method but the error still remain. Can't get susy to work so I'm going to use another grid system – Remi Mar 23 '14 at 14:24
  • To use Bundler first type 'bundle init' in Terminal at the desired directory.That will write a basic Gemfile. Load the Gemfile into nano and add in the items you want just as I have written below. Save the Gemfile. Then still in the same directory in Terminal type 'bundle install'. It should work but occasionally terminal asks you to install such and such a dependency first. – prasutagus Mar 25 '14 at 21:50

gem install compass --pre

if you ended up uninstalling the sass 3.3.0 gem you should reinstall that first.

    Yes, Susy 2 requires Sass 3.3. In order to use Compass with Sass 3.3, you need to use the Compass pre-release. – Miriam Suzanne Mar 22 '14 at 18:30
  • On Ubuntu, you will also need to install ruby1.9.1-dev package, or you will get this error: 'require': cannot load such file -- mkmf (LoadError) – Palantir May 26 '14 at 14:06

The best way without a doubt is to install Susy via the Compass Susy Plugin. This will avoid conflicts with other Compass projects that require the current version.

Commands:

gem install compass
gem install compass-susy-plugin

    This totally solve the issue for me on first attempt after spending a lot of time on other workarounds. Thanks Simon! – Selvin Ortiz Jun 30 '14 at 22:14

If you use Bundler, it will ensure that the gems in your Gemfile are the ones used by your project. So your Gemfile should specify "susy", "~>2.1.1" and "sass", "~>3.3.2", plus any other that you require, such as "breakpoint", "~>2.4.1". It then won't matter what versions are installed inside your Ruby gems folder. When you then do a 'bundle install', Bundler ensures that your project will only use the correct dependencies. This is, of course, a CLI instruction through the terminal. Alternatively, simply do a 'sudo gem uninstall sass -v 3.2.17', if you don't want to use Bundler.

  • The last suggestion (uninstall sass -v 3.2.17) is not possible. If I try that I get the error "If you remove this gem, these dependencies will not be met.) Continue with Uninstall [yN]". – Remi Mar 23 '14 at 13:21
  • Re the error 'if you uninstall ... etc.", it doesn't matter. Just re-install sass -v 3.3.0 and the correct dependencies will be added. – prasutagus Mar 24 '14 at 16:53

I'm using Ubuntu server 14.04 and I had the same problem and this is what I have done

  • Remove all my gems with gem uninstall gemname
  • Install bundler with sudo apt-get install bundler
  • Create a Gemfile as @Remy said before. Here is a Getting Started With Bundler Guide
  • And finally bundle install

After that, bundler create a Gemfile.lock where are specified all the needed gems and its versions, so you can use it safely.
