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.
