我的selenium版本是3.4.0，我的火狐的版本是：53.0.2，运行脚本的时候报错，请问各位大神有什么解决办法吗？

需要下载火狐浏览器的驱动程序。

catherinepanjl

是geckodriver.exe吗？放在跟eclipse.exe同一个路径下面？

catherinepanjl

是geckodriver.exe吗？跟eclipse.exe放在同一个路径了

掉渣饼

这是因为selenium3引入了driver对Firefox的进行操作，你要先下载个geckodriver，然后在 WebDriver driver = new FirefoxDriver(); 前面加上System.setProperty("webdriver.gecko.driver", "geckodriver.exe的路径");

catherinepanjl

我加了这句话：
System.setProperty("webdriver.gecko.driver", "E:\\eclipse-jee-mars-2-win32-x86_64\\eclipse\\geckodriver.exe");
但还是报之前的错
我的geckodriver的 版本是：geckodriver-v0.14.0-win64跟这个有关系吗？

finomy

firefox53要用geckodriver0.16和selenium3.4

yuyubill

驱动要与浏览器放在一个路径下，找到你的firefox.exe吧，把驱动扔这里

catherinepanjl

我把geckodriver0.16的EXE文件放在了firefox。exe一个目录下面，并且在代码中增加了System.setProperty("webdriver.gecko.driver", "geckodriver.exe的路径");这句话
现在程序报另外一个错：

加上两句：
System.setProperty("webdriver.gecko.driver","D:\\geckodriver.exe"); System.setProperty("webdriver.firefox.bin","D:\\Firefox\\firefox.exe");

catherinepanjl

加了：
System.setProperty("webdriver.gecko.driver", "C:\\Program Files (x86)\\Mozilla Firefox\\geckodriver.exe");
System.setProperty("webdriver.firefox.bin","C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"); 这两句话，但是还是报错
