Rbenv wrong gem installation path - can't find gem

I'm having an issue with rbenv and what I believe is an issue is of require trying to read from my system gems rather than from shims.

I'm trying to create a single script file without the overhead of needing bundle - though I've tried adding a Gemfile and put the script and Gemfile in the same directory.

Reproducible steps:

  1. brew install rbenv
  2. export PATH="$HOME/.rbenv/bin:$PATH" in my .zshrc
  3. Add eval "$(rbenv init -)" to my .zshrc
  4. Source: . ~/.zshrc
  5. rbenv install 2.6.3
  6. rbenv rehash
  7. rbenv global 2.6.3
  8. rbenv rehash for brevity
  9. Close terminal
  10. New terminal:
    • ruby -v = "ruby 2.6.3p62"
    • rbenv version = "2.6.3 (set by $HOME/Desktop/.ruby-version)"
  11. which ruby = "$HOME/.rbenv/shims/ruby"
  12. gem env
    • INSTALLATION DIRECTORY: $HOME/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0
    • USER INSTALLATION DIRECTORY: $HOME/.gem/ruby/2.6.0
    • RUBY EXECUTABLE: $HOME/.rbenv/versions/2.6.3/bin/ruby
    • EXECUTABLE DIRECTORY: $HOME/.rbenv/versions/2.6.3/bin
    • SPEC CACHE DIRECTORY: $HOME/.gem/specs
    • SYSTEM CONFIGURATION DIRECTORY: $HOME/.rbenv/versions/2.6.3/etc
    • RUBYGEMS PLATFORMS:
      • ruby
      • x86_64-darwin-18
    • GEM PATHS:
      • $HOME/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0
      • $HOME/.gem/ruby/2.6.0
  13. gem install colorize - this gem seems to work fine
  14. gem install httparty
  15. gem install pry

  16. File header:

    #!/usr/bin/ruby

require 'httparty'
require 'colorize'
require 'pry'
  17. ./file.rb
  18. Stack Trace for HTTParty

The stack trace shows there maybe in issue with multi_xml being a missing gem, but that was installed with httparty

Try executing ruby ./file.rb or add a .ruby-version file to the root where this file is located contents (2.6.2). The issue seems to be that #!/usr/bin/ruby refers to 2.3.0 and the file is executing in this context (however you did not install the gems in this context). The first option uses the ruby command which you have shown is 2.6.2. The second option specifies local to this file the ruby version for rbenv is 2.6.2 – engineersmnky

Rather than using /usr/bin/ruby which is the system installed Ruby, use the hashbang

#!/usr/bin/env ruby

This should point to your global rbenv backed Ruby.
