Make sure all dependencies in your Gemfile are available to your application.
$ bundle install
Gems may be installed to system gems or
BUNDLE_PATH(which defaults to
~/.bundle). Git repos will be checked out into to
Install your dependencies to a location other than
BUNDLE_PATH, in this case
Install all dependencies except those in groups that are explicitly excluded.

$ bundle install --without development test
Install all gems to
BUNDLE_PATH, regardless of whether those gems are installed in your system. Bundler will not install gems already in system gems by default, so this is especially useful if you're trying to package up an application with all dependencies unpacked.
$ bundle install --disable-shared-gems
Install all gems into
vendor/bundle, even gems that are already installed to your system and would normally be used from there instead of installed.
$ bundle install vendor/bundle --disable-shared-gems
