I get commands example list

This error probably occurs because you don't have which installed. I ran into this running inside an Amazon Linux Docker container.

specific_install/lib/rubygems/commands/specific_install_command.rb

Line 74 in f0bf470

unless system("which git") || system("where git")

I had the same issue within a Docker Container without which installed.

Instead of using which, where or whereis as well, I would recommend to use bash's builtin type to search for the git executable in PATH, 'cause It will give you also functions and aliases.

e.g.

 unless system("type -a git") 

as @FlatKey mentioned - the error occurs when docker images are created based on centos:8
