> If {{bundler}} is not installed, {{build_docs.sh}} attempts to install it locally but updating the {{$PATH}} environment variable is broken at least in my setup with ruby 2.5 because of this command failing:
> {code}
> > ruby -rubygems -e 'puts Gem.user_dir'
> Traceback (most recent call last):
>         1: from /usr/lib64/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'
> /usr/lib64/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require': cannot load such file -- ubygems (LoadError)
> > ruby -e 'puts Gem.user_dir'
> /home/nico/.gem/ruby/2.5.0
> {code}
> Additionally, the {{bundle}} binary is not even in that path::
> {code}
> > find ~/.gem/ruby/2.*/bin
> /home/nico/.gem/ruby/2.4.0/bin
> /home/nico/.gem/ruby/2.4.0/bin/bundle.ruby2.4
> /home/nico/.gem/ruby/2.4.0/bin/bundler.ruby2.4
> /home/nico/.gem/ruby/2.5.0/bin
> /home/nico/.gem/ruby/2.5.0/bin/bundle.ruby2.5
> /home/nico/.gem/ruby/2.5.0/bin/bundler.ruby2.5
> {code}
> but indeed here:
> {code}
> > ls ~/.gem/ruby/2.*/gems/bundler-*/exe/bundle
> /home/nico/.gem/ruby/2.4.0/gems/bundler-1.15.3/exe/bundle
> /home/nico/.gem/ruby/2.5.0/gems/bundler-1.16.1/exe/bundle
> {code}
