Can't start on Windows 8.1

[pepopowitz]

Apologies if you would have preferred this under the similar Windows 7 issue, but I didn't want to hijack it.

I am unable to start karma within Brackets, on Windows 8.1.

The only thing I have installed globally is karma-cli. Locally, I've installed karma, karma-brackets, karma-jasmine, and karma-chrome-launcher.

My karma.conf.js contains the 'brackets' reporter.

When I run karma start from a command window, karma starts up correctly with no errors or warnings, and executes my tests successfully.

When I try to start karma from within Brackets, I get this error in the Karma results window, with no further explanation -

Sorry :( There's been a problem (code: START_KARMA)

Within the Brackets settings, I have the karma executable path pointed at my local karma module (node_modules/karma). I am pretty sure it's the right path, because if I change it to node_modules/karmaXXX, it complains that it can't find a karmaXXX module in the local node_modules folder.

Here is my karma.conf.js -

module.exports = function(config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine'],
    files : [
      'app/lib/angular/angular.js',
      'app/lib/angular/angular-*.js',
      'test/lib/angular-mocks.js',
      'test/lib/sinon-1.10.2.js',
      'app/js/**/*.js',
      'test/unit/**/*.js'
    ],
    reporters: ['progress', 'brackets'],
    port: 9876,
    colors: true,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false
  });
};

Any thoughts on what I might be missing? I am a total newb at this, so it wouldn't surprise me in the least if I am doing something wrong.

Thank you!
