Are the SASS and Compass plugins in Sublime Text 3 sufficient when implementing a SASS project?

Question

Sass

Good afternoon.
Recently I have been studying front-end and quickly realized the usefulness of preprocessors.
The choice fell on SASS.
The question arose of the need to install Ruby and SASS and Compass through it.
The fact is that I have the corresponding packages in Sublime and everything is compiled through Koala in automatic mode. Everything is working.
Does it make sense for me to install Ruby, etc. in this case?
I create a project using the Nettuts+Fetch package (in Sublime Text3), using the https://github.com/akella/sass repository - as I understand it, there are all the necessary files (for which special thanks to its author).
