selenium-webdriver - 线程“主”org.openqa.selenium.WebDriverException 中的异常：java.net.ConnectException：无法连接到 localhost

Question

我只是想用 Selenium (3.14.0) 打开 Chrome。它适用于以下代码。

public class FirstClassForFirefox {    
public static void main(String[] args) {
 String projectLocation = System.getProperty("user.dir"); 
 System.setProperty("webdriver.chrome.driver",projectLocation+"/lib/chromedriver/chromedriver.exe");
 WebDriver driver = new ChromeDriver();
 driver.get("https://www.seleniumhq.org/");
 driver.quit();       
 }
}

---

另一方面，当我尝试使用以下代码打开 Firefox 浏览器时，发现了我的问题。

 public class FirstClassForFirefox {
 public static void main(String[] args) {

  String projectLocation = System.getProperty("user.dir");
  System.setProperty("webdriver.gecko.driver", projectLocation+"/lib/geckodriver/geckodriver-v0.23.0-win64.zip");
  System.setProperty("webdriver.firefox.bin", "C:\\Program Files\\Mozilla Firefox\\firefox.exe");
  WebDriver driver = new FirefoxDriver();
  driver.get("https://www.seleniumhq.org/");
  driver.quit();        
  }
}

我收到以下错误：-

请帮忙看看这有什么问题。可能是端口需要修改。谢谢！
