Answer 1

this happens when you use bundle install --deployment or bundle install --path=..., it generates .bundle/config with something like this:

---
BUNDLE_FROZEN: '1'
BUNDLE_PATH: vendor/bundle
BUNDLE_DISABLE_SHARED_GEMS: '1'

it could be done by one of you coworkers or the bundler/capistrano integration:

1. if it was your coworker then just remove and ignore it:

   rm -rf .bundle
   echo '.bundle' >> .gitignore
   

2. for capistrano rvm-capistrano describes how to disable it => https://github.com/wayneeseguin/rvm-capistrano#disabling-bundle---deployment-when-using-gemsets

Answer 2

before doing gem list make sure you use the application's gemset:

rvm use application_ruby@application_gemset
gem list

Be sure to replace application_ruby with your ruby version string and application_gemset to the gemset that is used by your rails application

Answer 3

There is a hidden directory called .bundle in the root of your directory. Remove that, then run bundle again.

Answer 4

According to bundler documentation the current default, in ops case, may have been set to vendor/bundle, e.g. by a prior execution bundle install --path vendor/bundle:

Further bundle commands or calls to Bundler.setup or Bundler.require will remember this location

Also check contents of $BUNDLE_PATH which shows where it's installed. Note: It's also possible it was installed to vendor/bundle via the --deployment option. See Deplyment mode 3.

As answered here, gem list will show only the gems installed using the --system option (see accepted answer and Caspar comment); use bundle list instead, to show gems installed in the application directory, i.e. via bundle install (without the --system option).
