【问题描述】：
我正在尝试加载 Firefox 以使用 selenium 测试我的 Web 应用程序。当我在 capabilities 中指定 firefox 时，我收到 SessionNotCreatedError: Unable to create new service: GeckoDriverService 错误。下面是它的样子：
var config = {
sauceUser: process.env.SAUCE_USERNAME,
sauceKey: process.env.SAUCE_ACCESS_KEY,
framework: 'jasmine2',
capabilities: {
browserName: 'firefox',
version: '57.0',
'screenResolution': '1920x1440'
},
specs: [
'*.spec.js'
],
jasmineNodeOpts: {
showColors: true,
defaultTimeoutInterval: 300000,
print: function() {}
},
params: {
defaultTimeout: 15000
}
};
以下是我的环境的详细信息：
OS: Ubuntu 16.04 LTS 64bit
Firefox: Quantum 57 64 bit
Selenium: 3.7.1
webdriver-manager: 12.0.6
gecko driver: 0.19.1
Protractor: 5.2.0
当我运行量角器端到端测试用例时，它会抛出此错误：

我尝试使用更新版本的 selenium 和 gecko 驱动程序，但这也无济于事。
我添加了marionette: true，但仍然遇到同样的错误。我也试过"javascriptEnabled": true, "acceptSslCerts": true，但没有成功。
