node-sass package (the dependency of gulp-sass) supports alpine linux since 4.1.0 (sass/node-sass#1589), installing a newer version of gulp-sass will fix that

[holyorb2]

"gulp-sass": "^3.1.0" - installed ok

Thanx

[petertogara]

Simply format your machine and start again

Upgrading "node-sass": "4.11.0" -> "node-sass": "4.12.0" worked for me
