BUNDLE-PACKAGE(1)BUNDLE-PACKAGE(1)NAMEbundle-package - Package your needed .gem files into your application
SYNOPSIS
bundle package
DESCRIPTION
Copy all of the .gem files needed to run the application into the ven‐
dor/cache directory. In the future, when running bundle install(1) bun‐
dle-install.1.html, use the gems in the cache in preference to the ones
on rubygems.org.
GIT AND PATH GEMS
Since Bundler 1.2, the bundle package 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.
REMOTE FETCHING
By default, if you simply run bundle install(1) bundle-install.1.html
after running bundle package(1) bundle-package.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 package under C Ruby, bundler will retrieve the ver‐
sion 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 actually 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 just 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 appro‐
priate for the platform you are on, you can run bundle install --local
to skip checking for more appropriate gems, and just 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 package on an identical machine and check in
the gems. For instance, you can run bundle package on an identical
staging box during your staging process, and check in the vendor/cache
before deploying to production.
