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

Question

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?

I'm not a Ruby dev, but it sounds like you need to uninstall sass 3.2.17. – Jihad

Sounds logical. I'll try installing a previous version – Kylakylah

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 – Kylakylah

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. – Dou

Answer 1

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]". – Kylakylah

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. – Dou

Answer 2

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. – Belayneh

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) – Trip

Answer 3

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! – Outdoor

Answer 4

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.
