问题描述

我正在使用 selenium 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

我的代码

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();
    }
}

但我无法启动 chrome.its 给出以下错误

But i am unable to launch chrome.its giving below error

推荐答案

此错误信息...

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 无法绑定到系统内分配的空闲端口.

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

根据讨论 获取无效端口错误. 和 无效的端口.正在退出...

"无效的端口.退出……"当分配给 chromedriver 的端口小于 0 或大于 65535 时发生.

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，或检查给定端口上是否有其他应用程序正在运行.
• 检查您的防火墙设置，很可能是防火墙配置导致了问题.
• 将 ChromeDriver 升级到当前的 ChromeDriverv2.38 级别.
• 将 Chrome 版本保持在 Chrome v66.x 级别.(根据 ChromeDriver v2.38 发行说明)
• 清理您的项目工作区，通过您的 IDE 并重建您的项目，仅使用所需的依赖项.
• 使用 CCleaner 工具清除所有操作系统杂事在执行测试套件之后.
• 如果您的基本Web Client 版本太旧，请通过卸载它Revo Uninstaller 并安装 Web Client 的最新 GA 和发布版本.
• 进行系统重启以释放端口.
• 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:第 1、2、7 和 8 步对于调试/解决您当前面临的问题至关重要.

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 WebDriver 变体，即 ChromeDriver 在特定端口上启动，例如65530如下:

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.
