Git推送Heroku引發Bundler錯誤

Question

我試圖讓一箇舊的Heroku應用程序運行，失敗迄今。 $ heroku stack返回

=== <app_name> Available Stacks 
    bamboo-ree-1.8.7 
    cedar 
* bamboo-mri-1.9.2 (prepared, will migrate on next git push) 

，推動的時候，我得到如下：

$ git push heroku master

當前的Gemfile：

source 'https://rubygems.org' 
ruby '1.9.3' 

gem 'bundler', '1.3.0.pre.8' 
gem 'rails', '~> 3.2' 
gem 'jquery-rails', '~> 2.2' 
gem 'slim', '~> 1.3' 
gem 'dynamic_form', '~> 1.0' 
gem 'state_machine', '~> 1.1' 
gem 'draper', '~> 1.1' 
gem 'bcrypt-ruby', '~> 3.0', :require => 'bcrypt' 
gem 'thin', '~> 1.5' 
gem 'twitter-bootstrap-rails', '~> 2.2' 

group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'less-rails', '~> 2.2' 
    gem 'coffee-rails', '~> 3.2.1' 
    gem 'therubyracer', '~> 0.11', :platforms => :ruby 
    gem 'uglifier', '>= 1.0.3' 
end 

group :development do 
    gem 'sqlite3', '~> 1.3' 
    gem 'pry', '~> 0.9' 
    gem 'better_errors', '~> 0.3' 
    gem 'binding_of_caller', '~> 0.6' 
end 

group :production do 
    gem 'pg', '~> 0.14' 
end 

似乎有一個問題與捆紮機，任何想法？

Answer 1

問題是由Gemfile中的2號線造成的：

ruby '1.9.3' 

從輸出我們可以看到捆紮機運行的版本：

Gemfile detected, running Bundler version 1.0.7 

但ruby指令似乎捆紮機1.2功能並不會與舊Bundler一起工作。我認爲你現在可以安全地刪除這個ruby '1.9.3'行。

當然，你有你的gemfile中的gem 'bundler', '1.3.0.pre.8'。但是這是雞與雞蛋的問題：在分析Gemfile之前不會安裝新的Bundler，但舊的Bundler無法解析它。
