java - org.openqa.selenium.SessionNotCreatedException : Unable to create new remote session in Mac

Question

我对 selenium 相当陌生，并尝试使用以下 java 代码调用 Firefox 浏览器。

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class google {

    public static void main(String[] args) throws InterruptedException {
        // TODO Auto-generated method stub
        System.setProperty("webdriver.gecko.driver", "/Users/gowtham/Desktop/Selenium/geckodriver");
        WebDriver driver = new FirefoxDriver();
        driver.get("http://google.com");
        Thread.sleep(1000);
        driver.quit();
    }
}

当我运行上述代码时，我的控制台上出现以下异常。

Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{marionette=true, browserName=firefox, moz:firefoxOptions=org.openqa.selenium.firefox.FirefoxOptions@7d70d1b1, version=, platform=ANY, firefox_profile=org.openqa.selenium.firefox.FirefoxProfile@2a742aa2}], required capabilities = Capabilities [{}]

我的机器上安装了 Firefox v52.0。

请分享您对此问题的看法。

目前我无法添加评论，所以在这里发布解决此问题的方法。确实，gecko驱动版本需要降级。对于使用“bonigarcia-webdrivermanager”的用户，请在实例化 FirefoxDriver 之前显式添加驱动程序版本:

FirefoxDriverManager.getInstance().setup("0.14.0");
