Question
I'm getting the following error when running any rails commands like rails s or rails c, it's also preventing my heroku app from starting (same error):

Russianapp/config/application.rb:7:in `<top (required)>': uninitialized constant Bundler (NameError)
from /Users/you/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:126:in `require'
Line 7 in the error message is:
Bundler.require(:default, Rails.env)
Doing the commands as bundle exec rails s succeeds, but that doesn't help the heroku app. I've verified which ruby, which rails and which bundler. I've also tried starting a new rvm gemset and reinstalling the bundle. The heroku error is identical:
/app/config/application.rb:7:in `<top (required)>': uninitialized constant Bundler (NameError)
running bundle check returns no issues.
Some similar questions suggested this:
bundle config --delete bin # Turn off Bundler's stub generator
rake rails:update:bin # Use the new Rails 4 executables
git add bin # Add bin/ to source control
But I tried it and got no changes. I'm on Rails 4
edit:
I was working in another app and ran rails g model and this popped up:
Bundler is using a binstub that was created for a different gem.
This is deprecated, in future versions you may need to `bundle binstub rails` to work around a system/bundle conflict.

update2: If I clone the repo and bundle install, and the try to run rails s or any rake task, I replicate the bundler errors. However, if I then do gem install bundler and gem install rake, the new repo will work fine. Uninstalling and reinstalling the two gems in my original repo will not fix the issue. glad I've found a quasi fix, but would still like to get to the bottom of this.
update3: I think I've narrowed it down to an issue with the gems, but not sure how to proceed. If I run the commands that trigger errors using my default gemset, there is no issue, it's only when I switch over to the gemset for this project that I get errors. I did not run bundle update before testing commands with the default gemset.
update4: I've cloned the repo on another machine and it replicates the issue. So I'm guessing it's time to start going back and checking commits from before this issue and see what happens? My other idea is to start commenting out gems / removing dependencies and seeing if that helps. Anything else I might want to look at?
After removing all gems, the warning with uninitialized constant is still present.
Solution
These commands from the bundler FAQ did the trick:
#remove project-specific settings
rm -rf .bundle/
# remove project-specific cached gems and repos
rm -rf vendor/cache/
# remove the saved resolve of the Gemfile
rm -rf Gemfile.lock
and then rebundling with bundle install
edit: heroku deploy was also failing to start up because it starts the server with bin/rails s and my binstubs were all wonky. to fix this: BUNDLE INSTALL --BINSTUBS, again from bundler docs
OTHER TIPS
I just removed the lock using rm -rf Gemfile.lock within my project directory's root folder, and re-ran bundle install and everything works perfect now.
I have problems like you, subscribe my case.
config/applicataion.rb:
require_relative 'boot'
require 'rails/all'
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)
module AppName
class Application < Rails::Application
config.load_defaults 5.2
end
end
where require_relative 'boot' is very important, such as config/boot.rb:
ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../Gemfile', __dir__)
require 'bundler/setup' # Set up gems listed in the Gemfile.
has including bundler library into application.
