FireFox 不是由 Selenium 启动的

【问题标题】：FireFox doesn't start by SeleniumFireFox 不是由 Selenium 启动的
【发布时间】：2015-10-05 19:06:48
【问题描述】：

我无法通过 selenium 启动 FireFox。

当我创建一个 FirefoxDriver 实例时，错误打开。 

public void startFireFox() {
    driver = new FirefoxDriver();
}

firefox 窗口是白页。和 Img 一样。 [![在此处输入图片描述][1]][1]

错误日志是这样的。我该如何解决这个问题？

【问题讨论】：

  • driver.get("some_URL_here"); 对浏览器有什么作用吗？

标签： java selenium selenium-firefoxdriver


【解决方案1】：

这是您使用的 Selenium Webdriver 版本 ('2.47.1') 与 Firefox 版本 ("41.0.1") 之间的兼容性问题。我在使用以前版本的 Webdriver 时遇到了同样的问题，当时，降级 Firefox 版本有所帮助。请检查 changelog 获取 Selenium Webdriver 或使用来自 here 的链接 CHANGELOG 并使用支持的 Firefox 版本。

【讨论】：

  • 编辑了我的答案以反映 Selenium-Java 的变更日志
【解决方案2】：

这是一个非常常见的问题，初学者不必担心，最好导入最后一个 selenium API，即 2.47.1，或者如果您使用的是旧版本的 selenium API，请尝试使用 Mozilla 低版本像 Mozilla 版本 31。我保证它会工作。

【讨论】：

  • 感谢您的回复。但不幸的是，我使用的是 API 版本 2.47.1。你有什么主意吗？构建信息：版本：'2.47.1'，修订：'411b314'，时间：'2015-07-30 02:56:46' 系统信息：os.name：'Windows 8.1'，os.ar
  • 我尝试了 Mozilla 版本 31。但我得到了同样的错误...这个错误只发生在这台电脑上。
  • 如果您的问题仍未解决，请不要担心，亲爱的，我随时准备提供帮助。请找到我的电子邮件 id :- shukla.imcl@gmai.com，让我知道我是否可以使用您的系统的团队查看器并解决问题。
