为什么我不能使用Selenium Chrome驱动程序

我尝试使用ChromeDrive，但出现错误或无法正常运行。

我用于测试的简单Java代码是：

@Test
public void testGoogleSearch() {
  System.setProperty("webdriver.chrome.driver", "lib\\chromedriver.exe");

  WebDriver driver = new ChromeDriver();
  driver.get("http://www.google.com/xhtml");
  Thread.sleep(5000);  // Let the user actually see something!
  WebElement searchBox = driver.findElement(By.name("q"));
  searchBox.sendKeys("ChromeDriver");
  searchBox.submit();
  Thread.sleep(5000);  // Let the user actually see something!
  driver.quit();
}
