TypeError: sass.sync is not a function
In order to get gulp init to work, I had to undo a change from #37, specifically this change.
To reproduce:
reproduction instructions
# USWDS doesn't work with a modern node version: https://github.com/uswds/uswds-gulp/issues/40
# so I'll build with an old version I guess. Computers.
#
# set our local nodejs to an old version capable of installing uswds-gulp
asdf local nodejs ref:v14.17.0
npm init
npm install --save uswds@latest
npm install -g gulp
asdf reshim
npm install autoprefixer gulp gulp-replace sass gulp-sass gulp-sourcemaps gulp-rename gulp-svg-sprite gulp-postcss postcss postcss-csso uswds uswds-gulp@github:uswds/uswds-gulp --save-dev
# copy the gulpfile and browserslist as instructed
cp node_modules/uswds-gulp/gulpfile.js .
cp node_modules/uswds-gulp/.browserslistrc .
# make a bunch of dirs for saving the output
mkdir -p dist/{sass,js,css,img,fonts}
# Update the gulpfile with paths:
----------------------------
// Project Sass source directory
const PROJECT_SASS_SRC = "./dist/sass";
// Images destination
const IMG_DEST = "./dist/img";
// Fonts destination
const FONTS_DEST = "./dist/fonts";
// Javascript destination
const JS_DEST = "./dist/js";
// Compiled CSS destination
const CSS_DEST = "./dist/css";
// Site CSS destination
// Like the _site/assets/css directory in Jekyll, if necessary.
// If using, uncomment line 106
// const SITE_CSS_DEST = "./path/to/site/css/destination";
----------------------------
gulp init
And that gulp init outputs:

The only change I had to make to get gulp init building was rolling line 20 back to const sass = require("gulp-sass");
We're using the recommended guidance outlined here https://github.com/dlmanning/gulp-sass#render-your-css
What does your gulp file look like?
I left detailed repro instructions in the "reproduction instructions" section above (not being snarky, it's collapsed and you might not have noticed it).
This is with the default gulpfile, the only thing I changed was to update the paths as instructed
I can confirm and I was able to reproduce the problem. Line 20 definitely should be updated to:
const sass = require("gulp-sass");
Here is the entire file, btw I also think it's sort of silly that the source directory settings are not just standardized and included with the paths ./assets/sass... etc which makes much more sense and will at least allow for an initial compilation. For new and/or inexperienced users it's easy to get this wrong, or at least include a recommended default in the files.

@tinyCoder32 I was able to get this working for me by changing:
const sass = require('gulp-sass');
to
const sass = require("gulp-sass")(require('sass'));
as suggested by bsang at https://github.com/uswds/uswds-gulp/issues/36
My gulp an node versions:
gulp -v
CLI version: 2.3.0
Local version: 4.0.2
node -v
v16.19.0
Just a heads up, we developed a new tool USWDS/Compile (hosted on NPM).
USWDS-Gulp isn't under active development anymore.
