python3+selenuim+firefox+geckodriver 报错：invalid argument: can't kill an exited p

selenium 版本3.141.0
python 版本3.7.7
firefox 版本68.6.0esr
geckodriver 版本0.26.0
始终在Linux下运行不来。头疼。
直接运行报错：
selenium.common.exceptions.WebDriverException: Message: invalid argument: can't kill an exited process
查看geckodriver.log
里面写着
Failed to open connection to "session" message bus: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11
Running without a11y support!
Error: no DISPLAY environment variable specified

这到底是不是版本对应不上的问题？？
firefox和geckodriver 都是最新版
firefox直接用yum remove firefox安装，geckodriver 是去官网下载的最新版本

[root@data-download bin]# geckodriver -h
