ruby-on-rails - 当我运行 rspec 时，我收到一条错误消息，声称 bcrypt-ruby 不是包的一部分

Question

我已经绝对确定 bcrypt-ruby 已列在 gemfile 中，我已经尝试要求不同版本的 bcrypt-ruby，我已检查它是否与所有其他 gem 安装在同一位置。我正在使用带有 RVM、rails 3.2 的 ruby​​ 版本 1.9.3。我试过卸载并重新安装 ruby 。当我运行 bundle exec rspec spec/ 时，我得到了这个:

Exception encountered: #<Gem::LoadError: bcrypt-ruby is not part of the bundle. Add it to Gemfile.>

非常感谢任何帮助。

这是 Gemfile

source 'https://rubygems.org'

gem 'rails', '3.2.1'

# Bundle edge Rails instead:

group :development, :test do

  gem 'guard-rspec', '0.5.5'
end

# Gems used only for assets and not required
# in production environments by default.

因为如果在开发过程中修改了gemfile，需要重启服务器。
