Install Sass on macOS

Install Sass on your Mac.

This is a simple short guide on how to install Sass on your Mac. If you receive an error whilst installing Sass, this article should provide a quick and simple solution. At the time of writing I am using macOS Sierra 10.12.5.

1. Sass installation via standard command line

As macOS comes pre-installed with Ruby, installing Sass should be a simple matter of going to the command line (Utilities / Terminal Window) and typing:

gem install sass

However, if the following error is thrown, an elevated command is required (proceed to step 2).

ERROR:  While executing gem … (Gem::FilePermissionError)
You don’t have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

2. Sass installation via elevated command line (sudo)

sudo gem install sass

This solves the issue of file permissions, and Sass attempts installation. However, if a new error is thrown as follows, we must continue a step further (proceed to step 3).

Building native extensions.  This could take a while…
ERROR:  Error installing sass:
ERROR: Failed to build gem native extension.

3. Install Command Line Developer tools first, then proceed with Sass installation

Tools installation: xcode-select ‑‑install

Sass installation: sudo gem install sass

Verify the install: sudo sass -v

Sass 3.5.1 (Bleeding Edge)

Congratulations, you have installed Sass. I hope this article has been of help to you, please see below for a concise screenshot of the process. If you would like to see a Windows version of this guide, please let me know.
