I have a materialized template which I want to integrate into my Phoenix application.
But I have been having trouble making this happen, Webpack is not loading my css and js files.
Below are the details of my configuration and the error.

######## APP.CSS #####################

@import "./phoenix.css";

@import "../app-assets/vendors/vendors.min.css";

@import "../app-assets/vendors/flag-icon/css/flag-icon.min.css";

@import "../app-assets/vendors/materialize-stepper/materialize-stepper.min.css";

@import "../app-assets/css/themes/vertical-dark-menu-template/materialize.css";

@import "../app-assets/css/themes/vertical-dark-menu-template/style.css";

@import "../app-assets/css/pages/form-wizard.css";

@import "../app-assets/css/custom/custom.css";

####### Webpack.config.js ###########################

const path = require('path');
const glob = require('glob');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const OptimizeCSSAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');

module.exports = (env, options) => ({
  optimization: {
    minimizer: [
      new UglifyJsPlugin({ cache: true, parallel: true, sourceMap: false }),
      new OptimizeCSSAssetsPlugin({})
    ]
  },
  entry: {
      './js/app.js': ['./js/app.js'].concat(glob.sync('./vendor/**/*.js'))
  },
  output: {
    filename: 'app.js',
    path: path.resolve(__dirname, '../priv/static/js')
  },
  module: {
    rules: [
      {
        test: /\.js?$/,
        loader: 'babel-loader',
        exclude: /(node_modules)/,
        
      },
      {
        test: /\.scss$/,
        use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader',]
      },{
        test: /\.(jpe?g|png|gif|woff|woff2|eot|ttf|svg)(\?[a-z0-9=.]+)?$/,
        loader: 'url-loader?limit=100000'},
    ],
  },
  plugins: [
    new MiniCssExtractPlugin({ filename: '../css/app.scss' }),
    new CopyWebpackPlugin([{ from: 'static/', to: '../' }])
  ]
});

This looks more like a NodeJS issue rather than something specific to phoenix.

Asking the “obvious” question; you’ve done an npm install from the directory that contains package.json? Have you confirmed that node-sass is available in node_modules?

Yeah, thank you @OldhamMade,
It is node version difference.
I upgraded the node from version 8.5.0 to 8.9.0 and it the issue got resolved.
Then changed webpack, webpack-cli “webpack”: “^4.36.0”,
“webpack-cli”: “3.3.9” respectively.
