Answer 1

Create a Gemset with RVM

rvm use 2.2.3@yourproject --create

After that install bundler gem

gem install bundler

and last step is to do bundle install

bundle install

Answer 2

The error shows you are using the system Ruby, not RVM. You need to tell Pow to use the right Ruby version. You need to create a .rvmrc file specifying which Ruby to use, and also create or edit a .powrc or .powenv file to tell Pow to load RVM. See the Pow docs on using RVM .

Answer 3

If you are using / upgrading to bundler 2 then please check this documentation:

https://bundler.io/guides/bundler_2_upgrade.html

from my experience basically, you need to be on RubyGems v2.5.0 or above otherwise you will see cannot load such file -- bundler/setup if you have require 'bundler/setup' . If you need to upgrade the rubygems you can do it by:

gem update --system

hope it helps. Thanks
