Unhandled rejection Error: not a directory

[th3fallen]

If this is indeed a support request please let me know and i'll move it. i belive it to be a bug however.

I'm submitting a bug report

Webpack version:
1.13.1

Webpack Karma version:
1.8.0

Karma version:
1.2.0

Please tell us about your environment:
OSX 10.12 beta 16A313a

Browser: Phantom

Current behavior:
when running tests i get the following failure:
Unhandled rejection Error: not a directory
full error with logging of current and path

this has only started after i began splitting app: and vendor: entry points

Expected/desired behavior:
should build and test correctly

webpack.config.js

var path = require('path');
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var autoprefixer = require('autoprefixer');
import getConfig from './config';
var packages = require('./package.json');

const config = getConfig(process.env.NODE_ENV);

// Strip out all keys starting with _
const envConfig = (config) => {
  Object.keys(config)
    .filter(k => k[0] === '_')
    .forEach(k => delete config[k]);
  return config;
};

let publicPath = (config.PREFIX || '').replace(/\/$/, '') + path.join(process.env.PUBLIC_PATH || '').replace(/^\./, '');

module.exports = {
  devtool: 'source-map',
  entry: {
    app: [
      './app/shared/vendor/segment',
      './app/main',
    ],
    vendor: Object.keys(packages.dependencies),
  },
  output: {
    publicPath: publicPath || '/',
    path: path.join(__dirname, 'dist'),
    filename: 'assets/js/[name]-[hash].js',
  },
  resolve: {
    root: path.join(__dirname, 'app'),
    modulesDirectories: [
      'node_modules',
    ],

        ENV: process.env.NODE_ENV,
      })),
    }),
    new ExtractTextPlugin('assets/css/[name]-[hash].css', { allChunks: true }),
    new HtmlWebpackPlugin({
      filename: 'index.html',
      template: 'app/index.html',
      chunksSortMode: 'dependency',
    }),
    new webpack.optimize.CommonsChunkPlugin({
      name: 'vendor',
      minChunks: Infinity,
    }),
  ],
  module: {
    loaders: [
      {
        test: /\.js$/,
        loaders: ['babel'],
        include: path.join(__dirname, 'app'),

      {
        test: /\.(scss|css)$/,
        loader: ExtractTextPlugin.extract('style', ['css?sourceMap', 'postcss', 'sass?sourceMap']),

      },
      {
        test: /\.json$/,
        loader: 'json',
      },
    ],
  },
  postcss: [autoprefixer({ browsers: ['last 2 versions'] })],
};

test.js

'use strict';
const watch = process.argv.slice(2) == 'watch';
var karma = require('karma');

new karma.Server({
  singleRun: !watch,
  configFile: __dirname + '/../karma.conf.js',
  reporters: ['junit', 'progress', 'coverage'],
  junitReporter: {
    suite: 'app',
    outputDir: './reports/',
  },
}, (exitCode) => {
  process.exit(exitCode);
}).start();

#149 also if that doesn't solve your issue link your karmaConfig

[th3fallen]

I should mention this exact config works fine if i dont have multiple entry points

karma.conf

import webpackConfig from './webpack.config';

module.exports = function (config) {
  config.set({
    port: 9876,
    runnerPort: 9100,
    logLevel: config.LOG_INFO,
    captureTimeout: 30000,
    basePath: '',

    frameworks: ['mocha', /*'sinon-stub-promise', 'sinon-chai', 'sinon',*/ 'chai'],

    files: [
      'node_modules/babel-polyfill/dist/polyfill.js',
      { pattern: 'app/**/*.spec.js', watched: false },
    ],

    reporters: ['progress', 'coverage'],

    preprocessors: {
      'app/**/*.js': ['webpack', 'sourcemap'],
    },

    client: {
      captureConsole: true,
    },

    webpack: {
      ...webpackConfig,
      module: {
        ...webpackConfig.module,
      },
      externals: {
        'cheerio': 'window',
        'react/addons': true,
        'react/lib/ExecutionEnvironment': true,
        'react/lib/ReactContext': true,
      },
    },
    webpackMiddleware: {
      // webpack-dev-middleware configuration
      stats: 'errors-only',
    },

    browsers: ['PhantomJS'],

    coverageReporter: {
      dir: 'reports/coverage/',
      includeAllSources: true,
      reporters: [
        { type : 'html', subdir: 'html' },
        { type: 'lcov', subdir: 'lcov' },
      ],
    },
  });
};

@th3fallen were you able to find a resolution, i have the exact problem myself.

[th3fallen]

@alphapilgrim i was, my solution was to use jest instead 🙈

[jacobthemyth]

FWIW, I had this same error and fixed it by deleting my entry in karma.conf.js.

karma.conf.js

var webpackConfig = require('./webpack.config')('test');
delete webpackConfig.entry;

module.exports = function(config) {
  config.set({
    // ...
    webpack: webpackConfig
  })
}

Closing as this is on an older version of karma-webpack that will not receive updates, if you are having the same issues with a current build, open another ticket and I'll assist as best I can!
