问题描述

我正在使用硒服务器独立jar- 3.11.0，最新的ChromeDriver-2.36和 Chrome版本66.0.3359.139

I am using selenium server standalone jar- 3.11.0, latest ChromeDriver-2.36 and Chrome version 66.0.3359.139

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class WebDriverBasics {

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", "C:\\Users\\surya\\Downloads\\Compressed\\chromedriver_win32_2\\chromedriver.exe");
        WebDriver driver=new ChromeDriver();
        driver.get("http://www.facebook.com");
        driver.manage().window().maximize();
    }
}

但是我无法启动chrome.its并给出以下错误消息

推荐答案

此错误消息...

Invalid port. Exiting...
?? ??, ???? ??:??:?? ????????? org.openqa.selenium.os.OsProcess checkForError
SEVERE: org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1)

...表示 OsProcess 无法绑定到系统中分配的可用端口.

...implies that the OsProcess is unable to bind to the assigned free port within your system.

根据讨论 Getting Invalid port error. > 和 Invalid port. Exiting...

"Invalid port. Exiting..." occurs when the port assigned to chromedriver is less than 0 or greater than 65535.

"Invalid port. Exiting..." occurs when the port assigned to chromedriver is less than 0 or greater than 65535.

解决方案

• 通过 CLI 执行netstat命令以查看您是否已达到可能打开的连接的限制，或者检查给定端口上是否正在运行其他应用程序.
• 检查防火墙设置，很有可能是防火墙配置引起了问题.
• 将 ChromeDriver 升级到当前的 ChromeDriver v2.38 级别.
• 保持 Chrome 版本处于 Chrome v66.x 级别. (根据ChromeDriver v2.38发行说明)
通过 IDE
• 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
• 使用 CCleaner 工具清除之前和之后的所有操作系统杂项在执行 test Suite 之后.
• 如果您的基本 Web客户端版本太旧，请通过来卸载. Revo Uninstaller 并安装最新版本的 Web客户端 GA和发行版.
• 进行系统重启释放端口.
• 执行您的@Test.

Solution

• Execute netstat command through CLI to see if you have reached limit of possible open connections or check if there is another application running on the given port.
• Check your firewall settings, there is a good chance that firewall configuration may be causing the issue.
• Upgrade ChromeDriver to current ChromeDriver v2.38 level.
• Keep Chrome version at Chrome v66.x levels. (as per ChromeDriver v2.38 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot to free up the ports.
• Execute your @Test.

注意:步骤1、2、7和8对于调试/解决您当前遇到的问题至关重要.

Note : Steps 1, 2, 7 and 8 are vital to debug/solve the issue you are currently facing.

作为替代方案，您可以强制

As an alternative you can force the WebDriver variant i.e. ChromeDriver to start on a specific port e.g. 65530 as follows:

• 代码块:

• Code Block:

System.setProperty("webdriver.chrome.driver","C:\\WebDrivers\\chromedriver.exe");
WebDriver driver= new ChromeDriver(new ChromeDriverService.Builder().usingPort(65530).build());
driver.get("https://www.google.com/");

• 控制台输出:

• Console Output:

  Starting ChromeDriver 83.0.4103.39 (ccbf011cb2d2b19b506d844400483861342c20cd-refs/branch-heads/4103@{#416}) on port 65530
  Only local connections are allowed.
  Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
  ChromeDriver was started successfully.
