compass compile gives error

[rampatra]

I am trying to compile the scss to css by compass compile and it gives me the below error:

➜  MyProject git:(master) ✗ compass compile
DEPRECATION WARNING on line 87 of /usr/local/lib/ruby/gems/2.4.0/gems/compass-core-1.0.3/stylesheets/compass/css3/_deprecated-support.scss: #{} interpolation near operators will be simplified
in a future version of Sass. To preserve the current behavior, use quotes:

  unquote('"$moz-"#{$experimental-support-for-mozilla} "$webkit-"#{$experimental-support-for-webkit} "$opera-"#{$experimental-support-for-opera} "$microsoft-"#{$experimental-support-for-microsoft} "$khtml-"#{$experimental-support-for-khtml}')

You can use the sass-convert command to automatically fix most cases.

Moreover, I think some info should be there in the README about compass and how to compile scss files.
