要求：我试图在最新的CentOS 7上运行无头selenium（使用PHPUnit）。
问题：似乎我正确安装了一切，但Firefox不启动，我的seleniumweb驱动程序卡在14:45:31.646 INFO - Launching Firefox... 用firefox命令，我得到以下输出
[admin@EE ~]$ /usr/bin/Xvfb :1 -screen 0 1024x768x24 & [1] 11932 [admin@EE ~]$ export DISPLAY=:1 [admin@EE ~]$ firefox firefox:11936): Gtk-WARNING **: Locale not supported by C library.
