Selenium无法打开Chrome浏览器

Question

下面是我在Selenium上试用的基本代码：

public static void main(String[] args) {
        // TODO Auto-generated method stub

        System.setProperty("webdriver.chrome.driver", "//Users//Downloads//chromedriver");      
        WebDriver driver= new ChromeDriver();
        
        driver.get("http://google.com");
        System.out.println( driver.getTitle());
}

但是我得到了下面的错误。无法打开chrome浏览器。我猜它崩溃了。

这在几周前还能用，但chrome浏览器被更新到了最新版本。我确实获取了最新的chrome驱动程序，但我仍然收到这个错误。

我使用的是Chrome版本89和ChromeDriver 89.0.4389.23

Answer 1

If you are using Chrome version 89, please download ChromeDriver 89.0.4389.23
If you are using Chrome version 88, please download ChromeDriver 88.0.4324.96
If you are using Chrome version 87, please download ChromeDriver 87.0.4280.88

从此处下载最新版本
