fpm 1.14.2 seems broken on RHEL8 / ruby <= 2.5.x #1918
Description
Hi!
Installing fpm on ruby 2.5.x looks broken due to dotenv dependency. The upgrade from 2.7.6 to 2.8.0 of dotenv seems to be the problem as it uses the endless iterator syntax introduced in Ruby 2.6 https://bugs.ruby-lang.org/issues/12912
bash> fpm --help

My workaround was to pin the dotenv gem to 2.7.6
gem install --version 2.7.6 dotenv
gem install fpm
gem uninstall --version 2.8.0 dotenv
