使用 yum 下载软件包时出错：权限被拒绝

我想在我的 centos 7 上安装简单的屏幕录像机，但是当我点击命令时

yum install simplescreenrecorder

输出如下：

在以下两个目录的开头，将python改为python2

sudo vi /usr/bin/yum
sudo vi /usr/libexec/urlgrabber-ext-down
sudo vi yum 
sudo vi yum-config-manager
sudo vi yum-debug-restore
sudo vi yum-groups-manager  
sudo vi yum-builddep
sudo vi yum-debug-dump 
sudo vi yumdownloader
