Question

I am ruby beginner. Two file is here first file attached to second file by using require. But first file does not load.

puts "First File"

second.rb

require 'first'
puts "Second File"

I am getting error:-

/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- first.rb (LoadError)
from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from second.rb:2:in `<main>'

Please tell us. How to solve this problem.

This should work. Look that the files are in same directory and look that you don't have typos in your file names. — Esa Mäkinen

require_relative "image_utils"

Based on your Ruby version, using require assumes that image_utils.rb is in the $LOAD_PATH (this requires additional setup) as Ruby 1.9 has removed the current directory from the load path. Use require_relative instead.

Ruby will first try to resolve the file by its absolute path. Then, if it isn't found then it will check on the $LOAD_PATH as mentioned above, if not then it will throw a LoadError
