Compass deprecation warning Sass 3.5 no support Ruby 1.9.3

Question

On my system, when I run compass -v or sass -v, it outputs deprecation warning:

Sass 3.5 will no longer support Ruby 1.9.3..

Running ruby -v gives:

ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-linux]

compass version is 1.0.3 and sass version is 3.4.22.

What I have done:

• Re-run gem install compass to update compass.
• Re-run gem install sass to update sass.

What should I do to resolve deprecation warning?

Answer 1

I was going to pick an answer but original answer was deleted. So I post here the answer.

To resolve deprecation warning, I had to install rvm which automatically upgrade ruby to 2.3.0. First, run

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

Then run

curl -sSL https://get.rvm.io | bash -s stable --ruby

to install rvm which also upgrade ruby to latest stable version. After that, however, I chose to upgrade my ruby using rvm.

rvm install 2.3.1

After it successfully upgrade ruby to version 2.3.1, I need to run

gem install compass

again because somehow compass installation was broken. After that, things works smoothly.
