Greetings,

does anyone succeed installing asciidoctor-pdf? When I run it, it claims to
need treetop ~> 1.5.0. However only 1.6.10 seems to be available:

[p@p rub]$ asciidoctor-pdf Systemdokumentation.adoc
Traceback (most recent call last):

Checked in 'GEM_PATH=/home/p/.gem/ruby/2.6.0:/usr/lib/ruby/gems/2.6.0', execute `gem env` for more information

Installing version 1.5.0 worked on their own platform.
[p@p rub]$ gem install treetop --version 1.5.0
ERROR:  Could not find a valid gem 'treetop' (= 1.5.0) in any repository
ERROR:  Possible alternatives: treetop

TIA
