线程＆＃34; main＆＃34;中的例外情况org.openqa.selenium.remote.UnreachableBrowserException：与远程浏览器通信时出错。它可能已经死了

Question

我尝试执行此脚本：

public class BuyMenShirt {

    public static void main(String[] args) throws InterruptedException
    {
        //Firefox driver setup

        String driverPath = "C:\\Users\\RW\\geckodriver-master\\";
        System.setProperty("webdriver.gecko.driver", driverPath + "geckodriver.exe");
        WebDriver driver = new FirefoxDriver();

        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.get("http://www.gap.com");

        WebElement menlink = driver.findElement(By.id("division5063"));
        menlink.click();

        WebElement shirtlink = driver.findElement(By.cssSelector("a.sidebar-navigation--category--link[href=/browse/category.do?cid=15043]"));
        shirtlink.click();
    }
}

但是，我收到了这个错误：

我做错了什么吗？我注意到UnreachableBrowserException之前我遇到了一些JavaScript错误。有关系吗？
