        export GEM_HOME=$HOME/.gem/ruby
        export PATH=$HOME/.gem/ruby/bin:$PATH
  

• RHEL (8.1 , 8.2)

        export PATH=$HOME/bin:$PATH
  

Step 2: Install Ruby on Rails

2.1) Add build dependencies

• RHEL (7.6, 7.7, 7.8)

   sudo yum install -y patch make gcc
  

• RHEL (8.1, 8.2)

   sudo yum groupinstall -y 'Development Tools'
   sudo yum install -y redhat-rpm-config zlib-devel.s390x zlib.s390x ruby-devel.s390x make gcc patch
  

• SLES 12 SP5

   sudo zypper install -y patch make gcc
  

• SLES 15 SP1

   sudo zypper install -y ruby2.5 ruby2.5-devel gcc zlib-devel gawk make patch tar gzip
  

• Ubuntu 16.04

   sudo apt-get update
   sudo apt-get install -y patch git
  

• Ubuntu (18.04, 20.04)

   sudo apt-get update
   sudo apt-get install -y ruby ruby-dev make gcc zlib1g-dev patch
  

2.2) Install Ruby on Rails via gem

      gem install rails -v 6.0.3.2                # For RHEL and SLES 12.x
      sudo gem install rails -v 6.0.3.2           # For Ubuntu and SLES 15 SP1
      sudo ln -sf /usr/lib64/ruby/gems/2.5.0/gems/railties-6.0.3.2/exe/rails /usr/bin/rails   # For SLES 15 SP1 only
