当导轨工作时，Pow无法正确加载gem

使用pow时出错，但与rails s完美配合。 以下是Heroku上相同代码的结果： www.contakapp.com

我相信chunky_png-1.2.8来自基础gem或一些相关问题。 所以我也提供了我的整个gem文件：

source 'https://rubygems.org' ruby '1.9.3' gem 'rails', '4.0.0' #views gem 'jquery-rails' , '~> 2.2.1' gem 'haml-rails' , '~> 0.4' #auth gem 'omniauth-facebook' , '~> 1.4.0' gem 'omniauth-linkedin' , '~> 0.1.0' #API gem 'twitter' , '~> 4.8.1' gem 'rest-client' , '~> 1.6.7' # models gem 'pg' gem 'coffee-rails' gem 'uglifier' gem "font-awesome-rails" gem 'sass-rails' gem "compass-rails", github: "milgner/compass-rails", ref: "1749c06f15dc4b058427e7969810457213647fb8" gem "zurb-foundation", "~> 4.3.0" group :development, :test do end group :development do end group :production, :staging do gem 'rails_12factor' end 

Gemfile.lock的

看起来Pow没有使用与shell会话相同的Ruby。 您可以使用Pow用户手册中的Ruby版本管理器了解如何使用相同版本的Ruby正确设置Pow 。
