When I add has_secure_password to the model (inherited from ActiveRecord::Base), error stating that “bcrypt-ruby is not part of the bundle” occurs.

Here the log is:

Started GET "/users" for 127.0.0.1 at 2012-02-19 16:37:12 +0900

Gem::LoadError (bcrypt-ruby is not part of the bundle. Add it to Gemfile.):
app/models/user.rb:3:in `<class:User>'
app/models/user.rb:1:in `<top (required)>'
app/controllers/users_controller.rb:1:in `<top (required)>'

I installed bcrypt-ruby by

$ gem install bcrypt-ruby
Building native extensions.   This could take a while...
1 gem installed
Installing YARD (yri) index for bcrypt-ruby-3.0.1...
Installing RDoc documentation for bcrypt-ruby-3.0.1...

but was no avail.

I tried

$ bundle exec rails server

but was no help.

If I comment out the line “has_secure_password”, this error does not come out.

How can I solve this problem?

    As the message says you need to add bcrypt-ruby to your Gemfile (at the root of the project).

    Adding

    gem "bcrypt-ruby"

    and then running bundle install should do the trick (this would fetch the gem if you hadn’t already installed it).

    You can specify specific versions to, eg

    gem "bcrypt-ruby", "~> 3.0.1"

    will get you the latest version that is >= to 3.0.1 but less than 3.1. You might do this if 3.0.1 has a bug fix you depend on and you’re happy to get more bug fixes but you don’t want major changes. There’s loads more info on the bundler website.
