在grunt中，我们通过以下方式在PhantomJS中执行单元测试。
karma: {
options: {
configFile: 'karma.conf.js',
runnerPort: 9876,
browsers: ['Chrome']
},
unitTestDev: {
browsers: ['PhantomJS'],
singleRun: true
}
}
grunt.registerTask('unitTest',['karma:unitTestDev']);
这是 karma.conf.js 文件。

});
};
执行"karma:unitTestDev"命令时，出现以下错误。

我们在Windows和Linux操作系统中遇到了上述问题。在Mac上，Karma成功地在PhantomJS上执行测试。
在Windows中，如果我们在Chrome浏览器中执行上述测试，而不是在PhantomJS上执行，则Karma可以成功地执行所有单元测试。
以下是Package.json文件中与Karma相关的依赖关系。
"phantomjs": "~1.9.7-3",
"karma": "~0.12.3",
"karma-chrome-launcher": "~0.1.3",

如果karma或grunt与PhantomJS有任何已知问题，请告诉我。
