openstack的packstack安装失败，错误如下-

/Stage[main]/Nova::Vncproxy/Nova::Generic_service[vncproxy]/Package[nova-vncproxy]/ensure: change from 'purged' to 'present' failed: Execution of '/usr/bin/yum -d 0 -e 0 -y install openstack-nova-novncproxy' returned 1: Transaction check error:
  file /usr/bin/websockify from install of python2-websockify-0.8.0-13.el7.noarch conflicts with file from package python3-websockify-0.10.0-3.el8.noarch
  file /usr/share/man/man1/websockify.1.gz from install of python2-websockify-0.8.0-13.el7.noarch conflicts with file from package python3-websockify-0.10.0-3.el8.noarch

上面你可以看到两个文件（/usr/bin/websockify &/usr/share/man/man 1/websockify. 1. gz）在python 2-websockify & python3-websockify之间发生冲突，因此必须删除其中任何一个文件，但是，
在检查系统安装的软件包时，我可以看到python 2-websockify仅在系统中可用，但没有安装在系统中。

[root@controller ~]# yum list | grep -i python2-web
python2-webob.noarch                     1.8.5-1.el7                   @centos-ceph-nautilus
python2-websocket-client.noarch          0.54.0-1.el7                  centos-ceph-nautilus
python2-websockify.noarch                0.8.0-13.el7                  centos-openstack-train

[root@controller ~]# yum list installed | grep -i python2-web
python2-webob.noarch              1.8.5-1.el7            @centos-ceph-nautilus

但是python3-websockify已经安装在系统中了，我无法删除它，因为nova-novnc包依赖于它。

[root@controller ~]# yum list installed | grep -i python3-web
python3-websockify.noarch         0.10.0-3.el8           @/python3-websockify-0.10.0-3.el8.noarch

现在，我怎么才能删除python 2-websockify.noarch这是甚至没有安装在系统上？&当它没有安装，那么为什么提到的错误

from install of python2-websockify-0.8.0-13.el7.noarch conflicts with file from package python3-websockify-0.10.0-3.el8.noarch

我试图删除python 2-websockify，但由于它没有安装，所以给出以下消息-

[root@controller ~]# yum remove python2-websockify-0.8.0-13.el7.noarch
