bundle-package(1) -- 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
|
|
`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
|
|
|
|
In Bundler 1.0, the `bundle package` command only packages `.gem` files,
|
|
not gems specified using the `:git` or `:path` options. This will likely
|
|
change in the future.
|
|
|
|
## REMOTE FETCHING
|
|
|
|
By default, if you simply run [bundle install(1)][bundle-install] after running
|
|
[bundle package(1)][bundle-package], 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 "http://rubygems.org"
|
|
|
|
gem "nokogiri"
|
|
|
|
If you run `bundle package` 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 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 appropriate 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.
