未能将rail应用程序部署到heroku（安装linecache19时出错（0.5.12）

Question

我试图将我的导航应用程序上传到Heroku。我正在使用Ruby 1.9.3。 应用程序可以部署在我的本地机器。

An error occurred while installing linecache19 (0.5.12), and Bundler cannot continue. 
    Make sure that `gem install linecache19 -v '0.5.12'` succeeds before bundling. 
! 
!  Failed to install gems via Bundler. 
! 
!  Heroku push rejected, failed to compile Ruby/rails app 

我试图进入这一行的Gemfile中

gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache' 

但它似乎并没有解决问题。

有人请指教？谢谢了前进帮助。 p.s .:对于新手问题真的很抱歉，我对Ruby on Rails开发非常感兴趣。

下面是我的完整的Gemfile

source 'http://rubygems.org' 

gem 'rails', '3.1.0' 

# Bundle edge Rails instead: 
# gem 'rails',  :git => 'git://github.com/rails/rails.git' 

# for Heroku deployment - as described in Ap. A of ELLS book 
group :development, :test do 
gem 'sqlite3' 
gem 'ruby-debug19', :require => 'ruby-debug' 
end 
group :production do 
gem 'pg' 
end 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
gem 'therubyracer'    
gem 'sass-rails', " ~> 3.1.0" 
gem 'coffee-rails', "~> 3.1.0" 
gem 'uglifier' 
end 

gem 'jquery-rails' 

# Use unicorn as the web server 
# gem 'unicorn' 

# Deploy with Capistrano 
# gem 'capistrano' 

# To use debugger 
gem 'haml'

linecache19是用于调试的瑰宝。生产中不需要它，所以你应该将它从生产中使用的宝石中排除。

将其添加到您已拥有的:development, :test组，并将其重新部署到文件顶部bundle。

group :development, :test do 
    gem 'sqlite3' 
    gem 'ruby-debug19', :require => 'ruby-debug' 
    gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache' 
end
