Selenium无法在Internet Explorer上启动会话

我想用Selenium测试我的代码，所以我用不同的浏览器启动了一个会话。 有了firefox和chrome，一切正常。 问题在于IE。我使用IEWebDriver 3.11.1.0、selenium 3.11.0和IE 11

我已经查过了，但没有找到答案

以下是日志：

E/launcher - Error forwarding the new session cannot find : Capabilities {baseUrl: http://localhost:7070, browserName: internet explorer, count: 1, specs:}

痕迹

参考这个：谢谢，但这不是我的问题。
