Unable to import gtk module . This maybe due to running without
$DISPLAYset .Exception was:
could not open display
Traceback ( most recent call last );
File "/usr/share/redhat-config-packages/
Mainwindow.py",line 11 in?
sys.exit(0)
Name Error :name 'sys' is not defined

然后我输入display
显示display : Unable to connect to X server().
