INstalled GEMS not running

I'm having a problem installing GEM's in my environment. I have been using SSH to do this work. [userna05@server ~]$ gem env RubyGems Environment: - RUBYGEMS VERSION: 2.0.14.1 - RUBY VERSION: 2.0.0 (2015-12-16 patchlevel 648) [x86_64-linux] - INSTALLATION DIRECTORY: /home/userna05/ruby/gems - RUBY EXECUTABLE: /usr/bin/ruby - EXECUTABLE DIRECTORY: /home/userna05/ruby/gems/bin - RUBYGEMS PLATFORMS: - ruby - x86_64-linux - GEM PATHS: - /home/userna05/ruby/gems - - GEM CONFIGURATION: - :update_sources => true - :verbose => true - :backtrace => false - :bulk_threshold => 1000 - "gem" => "--remote --no-rdoc --run-tests" - "gemhome" => "/home/userna05/ruby/gems" - "gempath" => [""] - "rdoc" => "--inline-source --line-numbers" - REMOTE SOURCES: - https://rubygems.org/ [userna05@server ~]$ gem list --local *** LOCAL GEMS *** addressable (2.5.1) colorator (1.1.0) ffi (1.9.18) forwardable-extended (2.6.0) jekyll-asciidoc (2.0.1) jekyll-sass-converter (1.5.0) jekyll-watch (1.5.0) liquid (3.0.6) mercenary (0.3.6) pathutil (0.14.0) public_suffix (2.0.5) rb-fsevent (0.9.8) rb-inotify (0.9.8) rouge (2.0.7, 1.11.1) rubygems-update (2.6.11) [userna05@server ~]$ Then I proceed with ASCIIDOCTOR GEM I need. [userna05@server ~]$ gem install asciidoctor Fetching: asciidoctor-1.5.5.gem (100%) Successfully installed asciidoctor-1.5.5 ERROR: While executing gem ...

Then I do another list of the local Gems [userna05@server ~]$ gem list --local *** LOCAL GEMS *** addressable (2.5.1) asciidoctor (1.5.5) <---- looks like it's been installed colorator (1.1.0) ffi (1.9.18) forwardable-extended (2.6.0) jekyll-asciidoc (2.0.1) jekyll-sass-converter (1.5.0) jekyll-watch (1.5.0) liquid (3.0.6) mercenary (0.3.6) pathutil (0.14.0) public_suffix (2.0.5) rb-fsevent (0.9.8) rb-inotify (0.9.8) rouge (2.0.7, 1.11.1) rubygems-update (2.6.11) I attempt to run it and I get [userna05@server ~]$ asciidoctor -bash: asciidoctor: command not found I changed to the directory where the BIN is located.
