java - Selenium 启动错误 : org. openqa.selenium.firefox.NotConnectedException : Unable to connect to host 127. 0.0.1 在端口 7055 上

标签 java firefox selenium selenium-webdriver selenium-firefoxdriver

当我尝试通过 java 运行一个非常简单的 selenium 脚本时，出现此错误。尝试创建新的 FireFoxWebDriver()

后一段时间会抛出此问题

我见过类似的错误，但它们已经很老了，似乎没有一个好的解决方案。我正在使用 selenium-java 和 selenium-firefox-driver 版本 2.51.0。我的 firefox 版本是 43.0.2，selenium 网站说他们支持最新版本的 firefox，所以我认为这不是问题。

非常感谢任何帮助，谢谢!

最佳答案

检查您的传递依赖项并确保您使用的确实是您认为的 Selenium 版本 (2.51.0)

回顾 FirefoxDriver 的历史，它对 connection.start() 的调用已经很长时间没有出现在第 247 行了(比如 2014 年) 。目前为 271。

我怀疑您使用的是 2.40.0 左右的版本，因为另一个 WebDriver 组件覆盖了您的首选版本。在这种情况下，您可能会遇到其他人过去遇到过的相同问题。

参见:Why am I getting the selenium error 'firefox-bin quit expectedly' and unable to connect to host 127.0.0.1 on port 7055等人。

更新:事实上，如果您读到 2/3，就会得到确认:

Build info: version: '2.42.2', revision: '6a6995d31c7c56c340d6f45a76976d43506cd6cc'

consensus看来问题是版本不兼容，因此您应该升级到最新的 WebDriver 版本。
