Question

I have two Ruby scripts, and I am calling those files and I am getting an error.

I have r1.rb and r2.rb. When I call r1.rb and r2.rb from r3.rb I get this error:

C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- r1 (LoadError)
        from C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from r3.rb:1:in `<main>'

r1.rb is:

def random
    rand(1000000)
end

r2.rb is:

def random
    (rand(26) + 65).chr
end

r3.rb is:

require 'r1'
require 'r2'

puts random

Answer 1

thumb rules when you use require, always use path in require statement [mostly when you use windows platform]

if you use load you need to place filename.rb but no need to pass file path. [First Check the requirement and use load because it is load every time in memory when call]

here I am modifying your code

require 'C:/PLACE YOUR FILE PATH HERE/r1'
require 'C:/PLACE YOUR FILE PATH HERE/r2'

puts random

Please let me know if this works for you

let me add one more things

Same way when you use irb, you have to do same way

>irb
irb(main):001:0> require 'c:/rubycode/test.rb'
=> true

@jdoe is suggest require_relative that’s good approach

but I am getting below error

irb(main):001:0> require_relative 'test'
LoadError: cannot infer basepath
        from (irb):1:in `require_relative'
        from (irb):1
        from C:/Ruby193/bin/irb:12:in `<main>'

irb(main):002:0> require_relative 'rubycode/test'
LoadError: cannot infer basepath
        from (irb):2:in `require_relative'
        from (irb):2
        from C:/Ruby193/bin/irb:12:in `<main>'

irb(main):003:0> require_relative 'c:/rubycode/test'
LoadError: cannot infer basepath
        from (irb):3:in `require_relative'
        from (irb):3
        from C:/Ruby193/bin/irb:12:in `<main>'

irb(main):004:0> require 'c:/rubycode/test'
=> true
irb(main):005:0>
