問題描述
您好，任何人都知道發生了什么或如何調試錯誤，如下所示.我所做的步驟是使用設置集線器命令并將節點注冊到集線器.在命令注冊節點之后.我可以看到日志為
Hi anyone know what is going on or how I can debug the error as following. the step I did is using setup hub command and register node to hub. after the command register node. I can see the log as
The node is registered to the hub and ready to use
但是，當我運行測試腳本時，我的錯誤打印為:
However when I run the test script I have error print up as:
selenium.common.exceptions.SessionNotCreatedException: Message: Unable to create new service: ChromeDriverService
二進制版本:
- selenium 獨立版本:3.14.0
- selenium 遠程驅動版本:selenium==3.14.1
- python 版本:3.6.4
腳本:
import os
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Remote(command_executor='http://localhost:4444/wd/hub',
desired_capabilities=DesiredCapabilities.CHROME)
設置中心:
#java -jar /Users/admin/selenium-server-standalone-3.14.0.jar -host localhost -role hub
注冊節點:
#java -jar /Users/admin/selenium-server-standalone-3.14.0.jar -role node
錯誤:

推薦答案
這個錯誤信息...
selenium.common.exceptions.SessionNotCreatedException: Message: Unable to create new service: ChromeDriverService
...暗示 ChromeDriver 無法啟動/生成新的 ChromeDriverService.
...implies that the ChromeDriver was unable to initiate/spawn a new ChromeDriverService.
commands 和 incompatibility 在您使用的二進制文件版本之間存在幾個問題，如下所示:
There are a couple of issues in the commands and incompatibility between the version of the binaries you are using as follows:
- 您的 JDK 版本是 1.8.0_91，非常古老.
- 將 JDK 升級到最新級別 JDK 8u181.
要注冊一個Selenium Grid Hub，您需要使用以下命令:
- Your JDK version is 1.8.0_91 which is pretty ancient.
- Upgrade JDK to recent levels JDK 8u181.
To register a Selenium Grid Hub you need to use the following command:
>java -jar /Users/admin/selenium-server-standalone-3.14.0.jar -role hub
要為ChromeDriver和Chrome注冊一個Selenium Grid Node，你需要傳遞ChromeDriver的絕對路徑 以及 Registration URI 的 Key 和 Value 如下:
To register a Selenium Grid Node for ChromeDriver and Chrome you need to pass the absolute path of the ChromeDriver along with the Key and Value of the Registration URI as follows:
>java -Dwebdriver.chrome.driver=/path/to/chromedriver.exe -jar /Users/admin/selenium-server-standalone-3.14.0.jar -role node -hub http://<IP_GRID_HUB>:4444/grid/register
你的代碼塊在我看來不錯.
You code block looks good to me.
