LoadError: cannot load such file -- <file_name>

Ubuntu 18 Ruby 2.6.3 $gem -v 2.7.6 bundler -v 2.1.4 Installed using "gem install bundler"

When running "bundle install" in a Ruby project: path from gem which hosting on Github has been added to $LOAD_PATH but then when I open $LOAD_PATH over irb , this path is absent there. And when I try to run app that use this gem it throws an error: LoadError: cannot load such file -- I prepare the examples: "exam" gem on github - https://github.com/dmitriy-sokolyanskiy/exam "check" app that use the gem above - https://github.com/dmitriy-sokolyanskiy/check my@pc:/check$ bundle install / update my@pc:/check$ bundle info exam my@pc:/check$ ruby runner.rb

Hei @dmitriy-sokolyanskiy!

I think the problem is that by using ruby runner.rb you're not telling ruby anywhere to use bundler to setup the dependencies. What you're doing manually inside irb is what bundler/setup does.

So either bundle exec ruby runner.rb or ruby -rbundler/setup runner.rb should get you back on track.

Let me know if that works for you, and please close the ticket if that's the case :)
