sass-loader can't resolve patternfly transitive dependencies

[rascio]

Hi!
I'm trying to setup a basic skeleton for a project. I would like to use patternfly-sass in my project, but I'm having bad time trying to setup it.
The problem seems to be in the sass files of patternfly, and for what I tried it seems that I need to modify that files to make it works, but maybe some magic trick exists.
I setup the sass loader in this way:

{
    test: /\.(scss|sass)$/,
    use: extractSass.extract({
      use: [{
          loader: "style-loader" // creates style nodes from JS strings
      }, {
          loader: "css-loader" // translates CSS into CommonJS
      }, {
          loader: "sass-loader", // compiles Sass to CSS,
          options: {
            includePaths: [path.resolve(__dirname, "node_modules")]
          }
      }]
    })
}

The I have in my main.scss:

@import '~patternfly-sass/assets/stylesheets/patternfly'

When I compile I have the following error:

File to import not found or unreadable: bootstrap/variables.
Parent style sheet: /Users/rascio/Projects/site-skeleton/node_modules/patternfly-sass/assets/stylesheets/_patternfly.scss
  in /Users/rascio/Projects/site-skeleton/node_modules/patternfly-sass/assets/stylesheets/_patternfly.scss (line 3, column 1)
 @ ./~/vue-style-loader!./~/css-loader?minimize!./~/vue-loader/lib/style-compiler?{"id":"data-v-356299a0","scoped":false,"hasInlineConfig":false}!./~/sass-loader/lib/loader.js!./~/vue-loader/lib/selector.js?type=styles&index=0!./private/src/App.vue 4:14-325
 @ ./private/src/App.vue
 @ ./private/main.js

In the _patternfly.scss:

// PatternFly SASS
@import "patternfly/variables";
@import "bootstrap/variables";
@import "patternfly/fonts";
@import "bootstrap/mixins";
@import "patternfly/mixin_overrides";
@import "bootstrap/normalize";

Patternfly doesn't have any bootstrap folder in the source so it can resolve the modules dependencies without the using of the prefix ~, meanwhile with my configuration I have to put it.

I don't get why I need to use the prefix to make it works and they don't?

Can I change something to use the patternly-sass module?

@rascio your can use https://github.com/sass/node-sass#importer--v200---experimental for this. THis is not related to sass-loader, some libraries add variable to define here search dependencies package or assets (your can create issue about this and do pr in patternfly). Sorry but seems won't fix in sass-loader.

@rascio seems duplicate #227.

Closing this out, please feel free to reopen if this doesn't related to your issue. Thanks!
