无法与SafariDriver扩展建立连接

我一直在使用量角器在AngularJS网络应用程序中运行e2e测试，并在Chrome和Firefox上进行了测试。将Safari浏览器添加到我的阵列时，将显示以下内容：

“无法与SafariDriver扩展建立连接”

我找到了一种在本地解决此问题的方法，但是当我们使用Codeship自动化构建时，我需要一种解决它的方法，而不必手动将驱动程序添加到selenium中并在Safari中启用。

我正在使用硒2.43.1

配置：

    exports.config = {
  baseUrl: 'http://localhost:9001',
  multiCapabilities: [{
    'browserName': 'chrome'
  }, {
    'browserName': 'firefox'
  }, {
    'browserName': 'safari'
  }],
  specs: ['e2e/app.js']
};

package.json：

谢谢-似乎很简单，但无法理解为什么它不起作用。
