浏览器打开，但似乎初始化无法返回驱动程序的实例。最初我只是尝试使用Selenium附带的默认firefox驱动程序，但是在网上冲浪我发现了一个可能的解决方案，使用gecko驱动程序并设置所需的功能到木偶。但我仍然会得到同样的问题，详情如下：
环境详情：
OS: macOs Sierra, 10.12.6
Browser: Firefox --> 55.0.3 (64-bit)
Driver: geckodriver
Selenium: 2.53.0
堆栈跟踪：
org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

答案 0 :(得分：0)
我认为你必须更新你的硒罐，因为你正在使用ff 55.0并且还要更新geckodriver
geckodriver的链接：https://github.com/mozilla/geckodriver/releases
selenium jar的链接：http://www.seleniumhq.org/download/
尝试一次，如果您有任何疑虑，请告诉我
