Hey guys,

I’m trying to install sass on my mac, I’ve tried using the sudo command and I’ve installed xcode-select a as well. I get the following error:

d192-075-242-026:~ tahirahmad$ sudo gem install sass
Building native extensions. This could take a while…
ERROR: Error installing sass:

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
