Less module build failed in webpack after migrating from grunt - css

Question

I can't figure out how to compile my less files to css and then include them in my build folder, without the app failing to run. Trying to build/run the application returns the following error:
ERROR in ./content/styles/less/ts.less
Module build failed:
#import "node_modules/bootstrap/less/mixins/buttons.less";
#import "node_modules/Font-awesome/less/font-awesome.less";
^
Can't resolve './node_modules/Font-awesome/less/font-awesome.less' in '/home/thinkpad/work/EPD.SPA/EpdSPA/content/styles/less'
in /home/thinkpad/work/EPD.SPA/EpdSPA/content/styles/less/ts.less (line 4, column 0)
# multi ./content/styles/less/for.less ./content/styles/less/kladd.less ./content/styles/less/ts.less
To clarify: These files have already proved to be working with grunt. The webpack migration triggered these errors.
I'm using the webpack config examples from here. My config file:
var webpack = require('webpack');
var globby = require('globby');
var path = require('path');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var CleanWebpackPlugin = require('clean-webpack-plugin');
var AssetsPlugin = require('assets-webpack-plugin');
var CopyWebpackPlugin = require('copy-webpack-plugin');
const extractLESS = new ExtractTextPlugin('stylesheets/[name]-two.css');
module.exports = {
entry: {
app: globby.sync(['./app/app.js','./app/app.run.js', './app/app.config.js', './app/**/*.js']),
styles: globby.sync(['./content/styles/*.css']),

Here you can see that the less files have been compiled to css and included in the public(build) folder. Why do i get errors, if the config file executes as intended?
Here it also shows that all the files are included in the application in the browser as well. I have checked all my dependencies and they are all running latest versions.

Answer 1

The path for the imports in the less files, were incorrect. Here is the working references:
#import "~bootstrap/less/variables.less";
#import "~bootstrap/less/mixins/buttons.less";
#import "~font-awesome/less/font-awesome.less";

Answer 2

I think the problem is with your font_awesome path.
Try to change import to (font_awesome instead of Font_awesome)
#import "node_modules/font-awesome/less/font-awesome.less";
