Karma - Chrome failed 2 times (cannot start). Giving up

Question

I've been trying to run my tests using karma-chrome-launcher, but everytime I run my tests it throws this error:

INFO [launcher]: Starting browser Chrome ERROR [launcher]: Cannot start Chrome

INFO [launcher]: Trying to start Chrome again (1/2).
ERROR [launcher]: Cannot start Chrome

INFO [launcher]: Trying to start Chrome again (2/2).
ERROR [launcher]: Cannot start Chrome

ERROR [launcher]: Chrome failed 2 times (cannot start). Giving up.

Here's my karma.conf.js code:

// Karma configuration
// Generated on Mon Mar 23 2015 14:04:19 GMT-0300 (BRT)

module.exports = function(config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: 'www',


    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jasmine'],


    // list of files / patterns to load in the browser
    files: [

      'js/factory/*.js',

      '../tests/**/*.js'
    ],


    // list of files to exclude
    exclude: [
    ],


    // preprocess matching files before serving them to the browser
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
    preprocessors: {

    // test results reporter to use

    reporters: ['progress', 'html'],

    htmlReporter: {
      outputFile: '../tests/report/index.html'
    },


    // web server port
    port: 9876,

    plugins : [

      'karma-chrome-launcher'
      //'karma-htmlfile-reporter'
    ],

    // enable / disable colors in the output (reporters and logs)
    colors: true,


    // level of logging
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_INFO,


    // enable / disable watching file and executing tests whenever any file changes
    autoWatch: true,


    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['PhantomJS'],


    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: false
  });
};

I'm installing the module here: https://www.npmjs.com/package/karma-chrome-launcher

Thanks!

I had the same problem and tried a lot of the suggested solutions I found, but what finally solved it for me was to delete the node_modules folder and getting everything new via npm install
