我已经尝试了一切，但没有用。

下面是我的程序：

public class demo {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver","C:\\Users\\Admin\\Desktop\\Internal job application\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("http://google.com");
    }
}

需要协助，以采取什么行动

Answer 1

您收到此错误，因为您的chrome浏览器未安装在默认安装目录中或硒无法找到可执行的chrome浏览器文件。

要解决此问题，您需要告诉程序chrome浏览器可执行文件所在的位置，为此您可以使用ChromeOptions类，如下所示：

public class demo {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver","C:\\Users\\Admin\\Desktop\\Internal job application\\chromedriver.exe");
        ChromeOptions options = new ChromeOptions();
        options.setBinary("/path/to/chrome/binary"); // Provide absolute executable chrome browser path with name and extension here
        WebDriver driver = new ChromeDriver(options);
        driver.get("http://google.com");
    }
}

希望对您有帮助...

1. 默认情况下在目标位置安装Chrome浏览器。

2. 在这一行：

   System.setProperty（“ webdriver.chrome.driver”，“目标文件”

destination to file不是已安装的Chrome浏览器的目标，而是下载的here chrome驱动程序的目标。
