Traceback (most recent call last): File "/usr/bin/firewall-cmd", line 24, in <module> from gi.

如下：

[root@localhost conf]# firewall-cmd --query-port=8020/tcp

Traceback (most recent call last):

  File "/usr/bin/firewall-cmd", line 24, in <module>

    from gi.repository import GObject

ImportError: No module named 'gi

其实当输入 firewall-cmd 系列的命令的时候都会报错

[root@localhost gi-1.2]# firewall-cmd --query-port=8020/tcp

Traceback (most recent call last):

  File "/usr/bin/firewall-cmd", line 24, in <module>

    from gi.repository import GObject

ImportError: No module named 'gi.repository'

此时应该启动或者查看centos7的防火墙：systemctl start  firewalld

还会报如下错
Job for firewalld.service failed because a timeout was exceeded.See "systemctl status firewalld.service" and "journalctl -xe" for details.
