The exec_annotaion can run on the directory that it belong instead of other directory

[honghh2018]

Hi guy,
Thank to develop the great tools for kegg annotation.
But i was so confusion about the exec_annotation shell script, on account of the exec_annotation only can be run on the folder that it belong. if i hope execute it in other directory with the absolute path in exec_annotation, it was complaint about below error:
internal:gem_prelude:1:in require': cannot load such file -- rubygems.rb (LoadError) from <internal:gem_prelude>:1:in internal:gem_prelude'
I had try to modifed the exec_annotation with below code, although it was error like above:
#!/usr/bin/env /Data/software/ruby-2.7.1/bin/ruby
# frozen_string_literal: true
#require_relative 'lib/kofam_scan'
require_relative '/Data/software/kofam_scan-1.3.0/lib/kofam_scan'
#require 'kofam_scan/cli'
require '/Data/software/kofam_scan-1.3.0/lib/kofam_scan/cli'
KofamScan::CLI.run(ARGV)
What should i do for this issue?
In addition, i want to exec it in everywhere by using the absolute path of exec_annotation. how can i configure it ?
Best,
Hanhuihong
