Question

我是一个红宝石，ruby on rails和heroku greenhorn，它正试图从Michael Hartl's Ruby on Rails 3.2 tutorial学习编码。

现在在本章的最开始，我没有将所有内容部署到Heroku。我收到此错误消息（但我没有计划如何解决此问题）：

$ git push heroku master

error: failed to push some refs to 'git@heroku.com:pacific-anchorage-8098.git'

My Gemfile如下所示：

source 'https://rubygems.org'

gem 'rails', '3.2.6'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
group :development, :test do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.10.0' 
end



# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.4'
  gem 'coffee-rails', '3.2.2'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.0'

group :test do
  gem 'capybara', '1.1.2'
end

group :production do
  gem 'pg', '0.12.2'
end

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

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

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'debugger'

我希望有人可以帮助我（抱歉，我是初学者 - >也是在Stackoverflow，大声笑）。 KR，Fabian

Answer 1

默认生成的Gemfile（使用rails 3.2.6）未指定要使用的jquery-rails版本。我建议做同样的事情，如下：

# remove version number, just like you would see in a fresh rails app
gem 'jquery-rails'

您需要的版本2.0.0依赖于栏目3.2.7.rc1 gem，您无法使用rails 3.2.6。

我在我的应用中使用了您的代码，无法将其捆绑到我的本地主机上。这让我想知道你是否在推到heroku之前自己尝试过。您应该始终首先在本地计算机上捆绑安装。

此外，您似乎已经碰到了sass-rails和coffee-rails所需的版本号。以下是您在干净的rails应用程序的Gemfile中所期望的：

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

Answer 2

我现在可以自己解决问题了。就是这样：

转到Gemfile并将gem 'rails', '3.2.6'的部分更改为gem 'rails', '3.2.7rc1'。
保存
运行bundle install --without production
运行git add .
像git commit -a -m "Heroku recommit
推送到git push之类的github并按照用户名和密码的说明进行操作
和最后git push heroku master

Answer 3

问题是jquery-rails gem需要一个不同版本的栏杆而不是捆绑文件中的rails gem。您可以尝试从jquery-rails中删除“2.0.0”，然后重试。 Bundle将安装一个版本的gem，它可用于版本3.2.6的铁路。
