Webpack 2 - Problems parsing node_module - node.js

Question

I'm unit testing with mocha-webpack v1.0.1, node v6.10. However, I'm getting an error from one of our node modules, where webpack couldn't parse a #. This is an internal library that we use that runs fine in another development environment. So, I'm confused why this is happening since you would think that a library in your node_module would be sort of self-sustaining and would know how to parse itself (and is validated as working in another environment).
Error in ./~/abc-components/src/abc-theme/index.scss
Module parse failed: /path/to/app/node_modules/abc-components/src/abc-theme/index.scss Unexpected character '#' (1:0)
You may need an appropriate loader to handle this file type.
| #charset "UTF-8";
| #import "abc-variables";
| #import "alert";
I believe # is an alias we use for resolving the module path in that library. I've modeled my setup after this tutorial.
From package.json:
"unit": "BABEL_ENV=test mocha-webpack --webpack-config build/webpack.test.conf.js --require test/unit/.setup src/**/*.spec.js --recursive --watch"
From build/webpack.test.conf.js config, including some comments of things I've tried:
var path = require('path')
var webpack = require('webpack')
var utils = require('./utils')
var config = require('../config')
// var nodeExternals = require('webpack-node-externals');
function resolve(dir) {
return path.join(__dirname, '..', dir)
}
module.exports = {
entry: {
app: './src/main.js'
},
resolve: {
modules: [path.resolve('./src'), "node_modules"],
extensions: ['.js', '.vue', '.json', '.ts'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'#': resolve('src')
}
},
// externals: [nodeExternals()],
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production'
? config.build.assetsPublicPath
: config.dev.assetsPublicPath
},

Include following config in loader.
module: {
loaders: [
{
test: /\.(scss|sass)$/i,
include: [
path.resolve(__dirname, 'node_modules'),
path.resolve(__dirname, 'path/to/imported/file/dir'), <== This solved the issue
],
loaders: ["css", "sass"]
},
]
},
