将karma remote reporter与Grails karma test runner插件一起使用时出现连接关闭错误

我正在尝试将我的karma\jasmine客户端测试集成到我们的grails环境中，以便在我们的CI服务器上使用

grails测试应用程序运行它们

从命令行使用
karma start path\to\karma.conf.js
可以正常运行测试

我的grails测试类定义如下：

import de.is24.util.karmatestrunner.junit.KarmaTestSuiteRunner
import org.junit.runner.RunWith

@RunWith(KarmaTestSuiteRunner.class)
@KarmaTestSuiteRunner.KarmaRemoteServerPort(8888)
@KarmaTestSuiteRunner.KarmaConfigPath("test/unit/javascript/karma.conf.js")
class JavaScriptUnitTestKarmaSuite {
}

karma配置是：

/*global module: false*/
module.exports = function (config) {
    "use strict";
    config.set({

        basePath: '.',

        frameworks: ['jasmine'],

        files: [
            /* files under test go here */
            'spec/**/*.js'
        ],

        reporters: ['remote'],

        plugins: [
            'karma-jasmine',
            'karma-junit-reporter',
            'karma-phantomjs-launcher',
            'karma-remote-reporter'
        ],

        remoteReporter: {
            host: 'localhost',
            port: '8888'
        },

         // web server port
        port: 9876,

        logLevel: config.LOG_INFO,

        autoWatch: false,

        browsers: ['PhantomJS'],

        singleRun: true
    });
};

运行这些测试的结果如下：

我认为问题可能是由于karma remote runner使用直接套接字而不是websockets，因此降级到grails插件引用的版本，但错误是相同的

我的package.json文件是：

{
  "devDependencies": {
    "karma": "~0.12.31",
    "jasmine-core": "~2.2.0",
    "karma-jasmine": "~0.2.2",
    "karma-phantomjs-launcher": "~0.1.4",
    "karma-coverage": "~0.2.7",
    "karma-junit-reporter": "~0.2.2",
    "karma-remote-reporter": "0.1.5"
  }
}

我在7号窗口跑步

任何帮助都会很好，我已经为此奋斗了一整晚
