Trying to build custom workflow with gulp, panini, mustache, sass and one of my problem is including partials from node_modules, here is example from main.scss file:
@import "node_modules/bootstrap/scss/mixins";
@import "settings";
How to avoid typing full path to _mixins.scss?
Your question is similar to this: Sass import not crawling node_modules to find appropriate package
You can include paths by passing the includePaths argument to gulp sass. e.g
.pipe($.sass({
includePaths: ['node_modules/bootstrap/scss/', 'another/path']
})
