Question

在我的Rails应用程序中，我尝试运行：

bundle exec rake -P RAILS_ENV=production

我收到以下错误：

我有以下Gemfile：

source 'https://rubygems.org'

ruby '2.1.2'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.0'

# Use sqlite3 as the database for Active Record
group :test, :development do
  gem 'sqlite3'
end

group :production do
  gem 'gem'
  gem 'rails_12factor'
end

gem 'sass-rails', '~> 4.0.3'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0',          group: :doc

# Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
gem 'spring',        group: :development

group :development, :test do
  gem 'rspec-rails', '~> 3.1.0'
  gem 'guard-rspec', '~> 4.3.1'
  gem 'factory_girl_rails', '~> 4.4.1'
  gem 'capybara', '~> 2.4.1'
end

gem 'slim', '~> 2.0.3'
gem 'devise', '~> 3.3.0'
gem "paperclip", "~> 4.2"

# Bootstrap
gem 'libv8'
gem "therubyracer"
gem "less-rails" 
gem "twitter-bootstrap-rails"

而且我不确定发生了什么。我试图推送到Heroku时发现了这个错误，然后我尝试在我的本地机器中重现......

Answer 1

检查您是否不小心将其添加到您的Gemfile中并将其删除：

gem 'gem'

Answer 2

在我的情况下，将gem 'openssl'添加到我的Gemfile中修复了它（RVM，使用了autolibs）。

警告：运行bundle exec rake时已经初始化了常量Gem :: VERSION
