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

Selenium server error: Unable to create new service chromedriverservice

提问by Planet_Man

I am trying to run webdriverio on my windows 10 computer and keep running into the same issue when trying to run my test js file. So I run this -jar /your/download/directory/selenium-server-standalone-3.5.3.jarto start the server and that comes out with this output

我正在尝试在我的 Windows 10 计算机上运行 webdriverio，并在尝试运行我的测试 js 文件时一直遇到同样的问题。所以我运行它-jar /your/download/directory/selenium-server-standalone-3.5.3.jar来启动服务器，然后输出

So after that I opened up a new command line prompt and ran my test.js file that looks like this

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);
    });

And this is the error I get

这是我得到的错误

Could someone please explain to me what I am doing wrong here? Also yes I already installed chromedriver via npm as well as wdio-chromedriver-service.

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

Update your ChromeDriver version via webdriver-manager, as follows:

通过 webdriver-manager 更新您的 ChromeDriver 版本，如下所示：

webdriver-manager clean
webdriver-manager update
webdriver-manager start

This will remove the older version, update with the latest stated in your built config, and restart the server. Hope this helps.

这将删除旧版本，使用构建配置中声明的最新版本进行更新，然后重新启动服务器。希望这可以帮助。

When you start your Grid Node, make sure the path to the chromedriver.exe in -Dwebdriver.chrome.driverparameter is correct: Example:

启动网格节点时，请确保-Dwebdriver.chrome.driver参数中chromedriver.exe的路径正确：示例：

java -Dwebdriver.chrome.driver="C:\DEV\eclipse\MainWorkspace\webdrivers\chromedriver.exe" -jar selenium-server-standalone-3.141.59.jar -role node  -hub http://localhost:4444/grid/register -nodeConfig node-config.json > node_output.log

The error you are seeing does gives us some hint about whats going wrong as follows :

您看到的错误确实为我们提供了一些有关问题的提示，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' }

It is clear from the error message that the ChromeDriveris not getting detected as you see the log message as Driver info: driver.version: unknown. The main reason of this error can be the incompatibility between the binaries you are using.

从错误消息中可以清楚地看出ChromeDriver没有被检测到，因为您看到的日志消息为Driver info: driver.version:unknown。此错误的主要原因可能是您使用的二进制文件之间不兼容。

Selenium Standalone Server is currently on Build 3.9.1.

Selenium 独立服务器目前在 Build 3.9.1 上。

It looks like you're running an older version of the standalone server. Perhaps the ChromeDriver version you're running might function better with an update to your Selenium Standalone Server?

看起来您正在运行旧版本的独立服务器。也许您正在运行的 ChromeDriver 版本在更新您的 Selenium 独立服务器后可能会运行得更好？
