尝试使用 selenium Web 驱动程序加载 Firefox 时出现 Java 代码错误

Question

即使我为壁虎驱动程序设置了正确的路径，我仍然遇到错误。

下面提到的例外情况：

Exception in thread "main" java.lang.IllegalStateException: The driver executable does not exist: C:\Selenium\geckodriver-v0.19.1-win64.exe

Answer 1

错误说明了一切：

Exception in thread "main" java.lang.IllegalStateException: The driver executable does not exist: C:\Selenium\geckodriver-v0.19.1-win64.exe

这意味着 GeckoDriver 二进制文件不存在 C:\Selenium\geckodriver-v0.19.1-win64.exe

解决方案

在使用 Selenium 3.x 时，您需要从 this site 下载 zip/tar 格式的 GeckoDriver 二进制文件，提取二进制文件并将其存储在您的任意位置系统。然后在System.setProperty() 行内的程序中，您需要提及 GeckoDriver 二进制文件的绝对路径，如下所示：

System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
