Issues with dependencies and installing Percona Toolkit

on Centos 6-8.el6.12.3.x86_64 with mysql Ver 14.14 Distrib 5.6.34, I am having trouble with installing Percona Toolkit:

yum install percona-toolkit-2.2.20-1.noarch.rpm
Loaded plugins: fastestmirror, security
Setting up Install Process
Examining percona-toolkit-2.2.20-1.noarch.rpm: percona-toolkit-2.2.20-1.noarch

    You could try using --skip-broken to work around the problem
    You could try running: rpm -Va --nofiles --nodigest

I’m not able to install the dependencies
e.g.
yum install perl-TermReadKey
Loaded plugins: fastestmirror, security
Setting up Install Process
Loading mirror speeds from cached hostfile

New to centos and not sure what is missing. Can you please help?

As of April 3, 2017, use the following command to install on CentOS:

Try

sudo perl -MCPAN -e 'install DBD::mysql'
