do not able to execute karma unit test in PhantomJS browser - unit-testing

Question

In grunt we execute unit test in PhantomJs by following ways.
karma: {
options: {
configFile: 'karma.conf.js',
runnerPort: 9876,
browsers: ['Chrome']
},
unitTestDev: {
browsers: ['PhantomJS'],
singleRun: true
}
}
grunt.registerTask('unitTest',['karma:unitTestDev']);
Here is karma.conf.js file.
// Karma configuration
// Generated on Thu Apr 03 2014 13:44:39 GMT-0500 (Central Daylight Time)
module.exports = function(config) {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['jasmine'],
// list of files / patterns to load in the browser
files: [
{pattern: 'dist/lib/jquery/dist/jquery.js', watched: false, served: true, included: true},
{pattern: 'dist/lib/jasmine-jquery/lib/jasmine-jquery.js', watched: false, served: true, included: true},

],

htmlReporter: {

templatePath: 'node_modules/karma-html-reporter/jasmine_template.html'
},
junitReporter: {
outputFile: 'build/unit-test/junit-report/test-results.xml',

},
// web server port

// 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: false,
// start these browsers
// available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
browsers: ['Chrome'],
// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: false
});
};
When execute "karma:unitTestDev" command, then getting following errors.
Running "karma:unitTestDev" (karma) task
INFO [karma]: Karma v0.11.14 server started at http://localhost:9876/

Warning: Task "karma:unitTestDev" failed. Use --force to continue.
Aborted due to warnings.
We are getting above issue in Windows and Linux OS. In Mac, karma successfully execute tests on PhantomJS.
In windows, If we execute above test in Chrome browser, instead of PhantomJS, then karma successfully execute all unit tests.
Here are karma related dependencies in Package.json
"phantomjs": "~1.9.7-3",
"karma": "~0.12.3",
"karma-chrome-launcher": "~0.1.3",
"karma-jasmine": "~0.1.5",
"karma-html-reporter": "~0.2.3",
"karma-junit-reporter": "~0.2.1",
"grunt-karma": "~0.8.2",
"karma-phantomjs-launcher": "~0.1.3"
Let me know if are there any known issue in karma or grunt with PhantomJS.

There is an issue with "Karma-phantomjs-launcher" v0.1.3. Change it to v0.1.4 and then it work fine.
