Capistrano: Use Bundle Gems from the Standard Gem-Home

Question

When deploying with Capistrano, I want to use installed stones instead of installing them in vendor.

Capistrano seems to ignore .gemrcand .bashrc, therefore, I tried this in deploy.rb:

require 'bundler/capistrano'

set :default_environment, {
  'GEM_HOME'     => '/some_path/.gem',
  'GEM_PATH'     => '/some_path/.gem',
  'BUNDLE_PATH'  => '/some_path/.gem'
}

My jewels are /some_path/.gem/gems, bin directory: /some_path/.gem/bin.

Answer 1

You can tell the binder where the stones should go (or, I suppose), and pass -local to install from the local cache, not from http://rubygems.org

bundle install --local --path='/some_path/.gem

Answer 2

If you do

require 'bundler/capistrano'

Put this in deploy.rb to install the package installation - path arg:

set :bundle_dir, "/path/to/gems"

Answer 3

config/deploy.rb, "" :

require "bundler/capistrano"
set :bundle_dir,     ""         # install into "system" gems
set :bundle_flags,   "--quiet"  # no verbose output
set :bundle_without, []         # bundle all gems (even dev & test)

Answer 4

This is a manifestation of the switch of the YAML core from Syck to Psych and all the incompatibilities it brought. The problem is that now you have to reinstall all your gems, because all installed gems have the wrong gemspec specification.
