DEPRECATION WARNING on line 87 of /Users/jgallaso/.asdf/installs/ruby/2.6.10/lib/ruby/gems/2.6.0/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.
