javascript – Selenium服务器错误：无法创建新服务chromedriverservice

我试图在我的Windows 10计算机上运行webdriverio并在尝试运行我的测试js文件时继续遇到同样的问题.所以我运行这个-jar /your/download/directory/selenium-server-standalone-3.5.3.jar
 启动服务器,这个输出出来了

13:06:19.808 INFO - Selenium Server is up and running

所以在那之后我打开了一个新的命令行提示符并运行了我的test.js文件,看起来像这样

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);
    });

这就是我得到的错误

{ Error: A new session could not be created.

有人可以向我解释我在这里做错了什么吗？也是的,我已经通过npm以及wdio-chromedriver-service安装了chromedriver.

解决方法:

您看到的错误确实给了我们一些关于错误的提示,如下所示：

   { type: 'SessionNotCreatedException',
     message: 'A new session could not be created.',
     orgStatusMessage: 'Unable to create new service: ChromeDriverService\nBuild info: version: \'3.5.3\', revision: \'a88d25fe6b\', time: \'2017-08-29T12:54:15.039Z\'\nSystem info: host: \'LAPTOP-9GIHGJ9I\', ip: \'10.0.0.243\', os.name: \'Windows 10\', os.arch: \'amd64\', os.version: \'10.0\', java.version: \'1.8.0_161\'\nDriver info: driver.version: unknown' }

从错误消息中可以清楚地看到ChromeDriver未被检测到,因为您将日志消息显示为Driver info：driver.version：unknown.此错误的主要原因可能是您正在使用的二进制文件之间的不兼容性.

>您的Selenium客户端版本是3.5.3发布2017-08-29T12：54：15.039Z
>我们不知道您的ChromeDriver版本.
>我们不了解您的Chrome浏览器版本.

解

一个快速的解决方案是：

>将Selenium Client版本更新到最近的级别,即Selenium 3.9.1
>将ChromeDriver版本更新到最近的级别,即ChromeDriver 2.35
>根据ChromeDriver v2.35发行说明,将Chrome浏览器版本更新为v62-64
>运行CCleaner工具以在执行Test Suite之前和之后擦除操作系统
>如果您的Chrome浏览器的基本版本已经从Revo Uninstaller卸载Chrome浏览器并安装最新的GA浏览器版本的Chrome浏览器
>执行你的测试.
