I have the following two files: main.rb and sort.rb located in the same folder. In main.rb I have the following code:
require 'sort'
Sort.insertion_sort([1,2,3,4]).each {|x| print "#{x}, "}
When I try and run this via ruby main.rb I get the following error:
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- sort (LoadError)
from <internal:lib/rubygems/custom_require>:29:in `require'
from main.rb:1:in `<main>'
Any ideas why? Thanks
The better way to use
require_relative "sort"
intead of
require "sort"
Thanks, @Jörg W Mittag.
Or you can add a path where ruby should search your files (can be a security risk):
$:.unshift File.join(File.dirname(__FILE__), ".") # current directory
require 'sort'
. was removed from the $LOAD_PATH. If you want to require a file relative to the location of the currently executing file, use require_relative, that's what it's there for.$LOAD_PATH manipulation is still a smell, since your package manager should do that for you. E.g. RubyGems automatically adds your Gem's lib directory, or any other directory/ies you specify to the $LOAD_PATH anyway, as does Bundler, and if you use some other package management system, then it's the packager's and/or the system administrator's job to do that. You shouldn't need to do that yourself.try require 'sort.rb' and check permissions
In Ruby 1.9.2, $: doesn't include the current directory ('.'). Either do relative_require instead, or do .$: << '.'
Joerg Mittag says that $: << '.' shouldn't be done because it's a security risk.
