ruby-on-rails-4 - 无法激活bcrypt-ruby(〜> 3.0.0)，已经激活了bcrypt-ruby-3.1.1。确保所有依赖项都已添加到Gemfile

Question

我有Rails 4.0.0应用程序。当我运行bundle install命令时，没有问题。这是我的GemFile。

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.0'

gem 'mysql2'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0.rc2'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'

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

# Use jquery as the JavaScript library
gem 'jquery-rails'

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

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

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

# Use Capistrano for deployment
# gem 'capistrano', group: :development

# Use debugger
# gem 'debugger', group: [:development, :test]

gem 'pry'
gem 'devise', git: "https://github.com/plataformatec/devise.git", branch: 'rails4'
gem 'bcrypt-ruby'
gem 'simple_form'
gem "therubyracer"
gem "less-rails" #Sprockets (what Rails 3.1 uses for its asset pipeline) supports LESS
gem "twitter-bootstrap-rails"
gem 'simple_form'
gem 'jquery-ui-rails'

group :development, :test do
  gem 'rspec-rails', '~> 2.0'
  gem 'cucumber-rails', :git => "https://github.com/cucumber/cucumber-rails.git", :branch => "master_rails4_test", :require => false
  gem 'database_cleaner'
  gem 'factory_girl'
  gem "factory_girl_rails", "~> 4.0"
  gem "database_cleaner"
  gem "awesome_print"
end

这是我的Gemfile.lock

我该如何解决？

Answer 1

在您的gemfile中，您没有指定版本，因此要安装的最新版本的bcrypt-ruby是3.1.1，但是您需要的是3.0.0到3.0.9之间的任何版本。您可以通过添加如下版本约束来实现：

gem 'bcrypt-ruby', '~> 3.0.0'

版本要求来自ActiveModel的SecurePassword，当前它对bcrypt-ruby（〜> 3.0.0）有明确的依赖性。您可以看到对 github的依赖性。执行此代码时，它将查找未安装的3.0.0至3.0.9版本，因此会引发错误。

几天前，此依赖项刚刚更新为“〜> 3.1.0”，但尚未进入rails activemodel gem。完成后，您将必须相应地更新版本。如果您好奇的话，这是 commit。
