Selenium webdriver 关闭selenium webdriver连接时量角器测试失败 问题

我试图让AppVeyor使用量角器和SeleniumWebDriver运行一些e2e测试

在我的本地机器上一切正常，但当AppVeyor量角器上的构建和测试由于selenium webdriver中的未找到方法而以代码1退出时，似乎是这样。我试图获取有关错误消息的一些信息，但我的搜索没有找到任何地方。大多数结果来自于使用Java的后端测试

以下是构建日志的一个片段：

selenium服务器正在运行，测试通过，但当服务器即将关闭时，会发生错误

安装程序 在构建开始时，我运行

npm install

，然后将

node\u modules\\.bin\\webdriver manager update--standalone

作为安装后脚本运行

量角器通过gulp量角器插件和gulp任务运行，selenium standalone jar在量角器配置中定义，如下所示：

exports.config = {
    seleniumServerJar: '../node_modules/protractor/selenium/selenium-server-standalone-2.47.1.jar',

    specs: ['Tests/**/*e2e.spec.js'],

    resultJsonOutputFile: 'results-protractor.json',

    allScriptsTimeout: 30000
};

完整的构建日志可在此处查看： 为吵闹的日志道歉。部署日志在控制台中非常响亮，在AppVeyor afaict上无法配置

本地日志信息 如前所述，在我的本地机器上一切运行正常。这是量角器运行的日志

这个问题可以通过java运行时引擎的以下参数来解决

localSeleniumStandaloneOpts: {
        args: ['-Djna.nosys=true']
},
