NAME

       bundle-cache - Package your needed .gem files into your application

SYNOPSIS

       bundle cache

DESCRIPTION

       Copy  all of the .gem files needed to run the application into the vendor/cache directory. In the future,
       when running [bundle install(1)][bundle-install], use the gems in the cache in preference to the ones  on
       rubygems.org.

GIT AND PATH GEMS

       The  bundle  cache command can also package :git and :path dependencies besides .gem files. This needs to
       be explicitly enabled via the --all option. Once used, the --all option will be remembered.

SUPPORT FOR MULTIPLE PLATFORMS

       When using gems that have different packages for different platforms, Bundler supports  caching  of  gems
       for  other  platforms where the Gemfile has been resolved (i.e. present in the lockfile) in vendor/cache.
       This needs to be enabled via the --all-platforms option. This setting will be remembered  in  your  local
       bundler configuration.

REMOTE FETCHING

       By   default,  if  you  run  bundle  install(1)](bundle-install.1.html)  after  running  bundle  cache(1)
       bundle-cache.1.html, bundler will still connect to rubygems.org to check whether a platform-specific  gem
       exists for any of the gems in vendor/cache.

       For instance, consider this Gemfile(5):

           source "https://rubygems.org"

           gem "nokogiri"

       If  you  run  bundle  cache  under  C  Ruby, bundler will retrieve the version of nokogiri for the "ruby"
       platform. If you deploy to JRuby and run bundle install, bundler is forced to  check  to  see  whether  a
       "java" platformed nokogiri exists.

       Even  though  the  nokogiri  gem  for  the  Ruby  platform is technically acceptable on JRuby, it has a C
       extension that does not run  on  JRuby.  As  a  result,  bundler  will,  by  default,  still  connect  to
       rubygems.org to check whether it has a version of one of your gems more specific to your platform.

       This  problem  is  also  not  limited  to the "java" platform. A similar (common) problem can happen when
       developing on Windows and deploying to Linux, or even when developing on OSX and deploying to Linux.

       If you know for sure that the gems packaged in vendor/cache are appropriate for the platform you are  on,
       you  can  run  bundle  install  --local  to  skip checking for more appropriate gems, and use the ones in
       vendor/cache.

       One way to be sure that you have the right platformed versions of all your gems is to run bundle cache on
       an identical machine and check in the gems. For instance, you  can  run  bundle  cache  on  an  identical
       staging box during your staging process, and check in the vendor/cache before deploying to production.

       By  default,  bundle  cache(1)  bundle-cache.1.html  fetches  and  also  installs the gems to the default
       location. To package the dependencies to vendor/cache  without  installing  them  to  the  local  install
       location, you can run bundle cache --no-install.
