Gulp issues - custom version

[Marten4n6]

I'm trying to change color variables as shown in the documentation.

Deprecations:

$ npm install
npm WARN deprecated gulp-util@3.0.8: gulp-util is deprecated - replace it, following the guidelines at https://medium.com/gulpjs/gulp-util-ca3b1f9f9ac5
npm WARN deprecated node-uuid@1.4.0: Use uuid module instead

$ gulp build
assert.js:351
    throw err;
    ^

$ gulp -version

[12:58:15] Local version 4.0.0

For anyone having this issue, the solution is to downgrade your gulp version:

# Show available versions of gulp
$ npm view gulp versions
# Install an older version
$ npm install gulp@3.8.11
# Verify the newly installed version
$ gulp -version 

# "gulp build" should now work, if it doesn't mess with the version number

Maybe it's a good idea to specify the required gulp version in the documentation?
Thanks.

Or update the package.json to require gulp@3.9.1 rather than its latest version?

I'm confused. Why is this closed if it hasn't been fixed? Per the package.json this repo is compatible with "gulp": "latest" which clearly it is not! This issue needs to stay open till either the repo is indeed compatible with latest or has locked its gulp version to a compatible one.

Also the documentation states running gulp build is all you need. This is not true. when installed via npm install the gulp executable is not in the users' path by default. Either the user needs to execute npx gulp build or the package.json file needs to define a "scripts" section.
