运行WebdriverIO测试时，抛出“无法创建新会话”错误

Question

我正在使用selenium.js做一个测试，它是使用WebdriverIO和Node.js编写的。运行测试时，出现错误"driver.version: unknown"。

我已经验证了我的系统PATH变量和chrome驱动程序版本。但是找不到根本原因。

selenium.js：

var webdriverio = require('webdriverio');
var options = {
    desiredCapabilities: {
        browserName: 'chrome'
    }
};

webdriverio
    .remote(options)
    .init()
    .url('http://www.google.com')
    .getTitle().then(function(title) {
        console.log('Title was: ' + title);
    })
    .end()
    .catch(function(err) {
        console.log(err);
    });

错误：

{ Error: A new session could not be created.
    at end() - C:\Projects\Testing_Tool_Evaluation\my-first-react-test\selenium.js:15:6

运行测试后，我可以在硒服务器中观察到以下功能
