ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../Gemfile', __dir__)

require 'bundler/setup' # Set up gems listed in the Gemfile.

bundler/setup can not be required.

A same problem is with passenger, to start rails app with that:

Have anybody a same problem with ruby 2.5.0?

Answer 1

Fix is simple: update RubyGems min up to 2.7.4 version

gem update --system

RubyGems 2.7.4 includes bug fixes.

Unfortunately, the problem has returned. See github.com/travis-ci/travis-ci/issues/8978. – Rattlebox

Answer 2

Sadly the only solution here is to upgrade Bundler to >= 1.16.1. See https://github.com/heroku/heroku-buildpack-ruby/pull/738 for an example where this is fixed in theory, but is blocked by Heroku unfortunately.

Upgrade to Bundler 1.16.1+ and you won't have any more issues.
