Setting the environment in Gemfile for bundling install/update based on a customize file

Question

hi, all I build a sinatra app, the main files for bundling as the following,

environment.rb

require \'sinatra\'
require \'sequel\'

ENV[\'RACK_ENV\'] = \         


        

Answer 1

When doing a bundler require you can specify which groups to be required.

For example:

require 'rubygems'
require 'bundler'

if ENV['RACK_ENV'] == 'development'
  Bundler.require(:default, :development)
else
  Bundler.require(:default)
require 'sinatra'

More info on the bundler site gemfile specifications found here.
