ruby-on-rails - Rails 3.2.13 - Gem::LoadError，无法激活 gem

Question

在我的 Rails 3.2.13 应用程序中，我有布局文件 <% if signed_in? %> ，并且此行导致以下错误:

can't activate bcrypt-ruby (~> 3.0.0), already activated bcrypt-ruby-3.1.1-x86-mingw32. Make sure all dependencies are added to Gemfile.

signed_in 方法放在我的 session_helper.rb 中:

def signed_in?
    !current_user.nil?
end

def current_user
    @current_user ||= User.find_by_remember_token(cookies[:remember_token])
end

我尝试删除 Gemfile.lock 然后运行 ​​ bundle install ，但没有任何影响。我也尝试更改 Gemfile.lock 文件的内容，但它也不起作用。

请提供一些关于我应该做什么的指示，谢谢!

我的 Gemfile 看起来像这样:

source 'https://rubygems.org'

gem 'rails', '3.2.13'
gem 'bootstrap-sass'
gem 'bcrypt-ruby'
gem 'faker'
gem 'will_paginate'
gem 'bootstrap-will_paginate'

  gem 'sqlite3'
  gem 'rspec-rails'
end

group :development do
  gem 'annotate', '2.5.0'
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

group :test do
  gem 'capybara', '1.1.2'
  gem 'factory_girl_rails', '4.1.0'
  gem 'cucumber-rails', '1.2.1', :require => false
  gem 'database_cleaner', '0.7.0'
  # gem 'launchy', '2.1.0'
  # gem 'rb-fsevent', '0.9.1', :require => false
  # gem 'growl', '1.0.3'
end

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

和我的 Gemfile.lock 看起来像这样:

运行 gem list bcrypt-ruby给出:

*** LOCAL GEMS ***

bcrypt-ruby (3.1.1 x86-mingw32, 3.0.1 x86-mingw32, 3.0.0 x86-mingw32)

Answer 1

您在使用 Rails 的 has_secure_password 功能吗？如果是这样，您必须使用 bcrypt-ruby 3.0.x。

确保你的 Gemfile 中有这个:

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