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

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

Solution

  • 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.
