   An error occurred while installing rdiscount (2.0.7.2), and Bundler cannot
   continue.
   Make sure that `gem install rdiscount -v '2.0.7.2'` succeeds before bundling.

！！无法通过Bundler安装gem。！！ Heroku推送拒绝，无法编译Ruby / rails app

这是我的Gemfile：

source 'https://rubygems.org'

gem 'rails', '3.2.13'
gem 'bootstrap-sass', '2.1'
gem 'google-webfonts'
gem 'postmarkdown'
gem 'rdiscount', "~> 2.0.7.2"

group :development, :test do 
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.11.0'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.5'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.2'

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

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

我添加postmarkdown gem之后似乎开始遇到问题。我还在命令行中运行了`gem install rdiscount -v'2.0.7.2'，但我仍然收到此错误。感谢您的帮助，或者如果您需要更多信息，请告知我们。

Answer 1

你可以在你的gemfile中添加ruby "1.9.3"，如

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

然后再次bundle install

Answer 2

尝试将ruby版本添加到Gem文件

source :rubygems
ruby "1.9.3"

gem 'rails', '3.2.13'
gem 'bootstrap-sass', '2.1'
gem 'google-webfonts'
gem 'postmarkdown'
gem 'rdiscount', "~> 2.0.7.2"
....

ruby 1.9.2似乎与heroku有问题

无法将代码推送到heroku
