Question

所以我试图运行rake db：migrate并在终端中收到此错误？

我最近将bcrypt添加到我的gemfile中，因为我尝试运行“rails destroy devise user”，它给了我一个关于bcrypt的错误然后我去堆栈溢出，有人说要添加到你的gemfile。但它没有给我的特定版本，（是一个过时的宝石文件）我刚刚添加了这个：

source 'https://rubygems.org'
ruby '2.2.3'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.0'

# Use sqlite3 as the database for Active Record


# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-script-source', '1.8.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 1.2'
gem 'bootstrap-sass'
gem 'devise', '~> 3.1.0.rc2'
gem 'bcrypt-ruby'

group :development, :test do
    gem 'sqlite3'
end
group :production do
    gem 'pg'
    gem 'rails_12factor'
end
group :doc do

  gem 'sdoc', require: false
end

运行bundle install从终端安装bcrypt并重新运行bundle exec rake db:migrate

rake db：migrate不起作用并在终端中给出错误
