想用 bootstrappers 快速產生一個專案卻出現以下問題：

看來是 devise 這個套件出了問題。
起初谷歌了一下，是找到相類問題，但並沒有解法。
後來嘗試手動輸入安裝指令：
martin@martins-mba:~/myapp$ rails g devise:install
create config/initializers/devise.rb
create config/locales/devise.en.yml
===============================================================================
Some setup you must do manually if you haven't yet:
1. Ensure you have defined default url options in your environments files. Here
is an example of default_url_options appropriate for a development environment
in config/environments/development.rb:
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
In production, :host should be set to the actual host of your application.
2. Ensure you have defined root_url to *something* in your config/routes.rb.
For example:
root :to => "home#index"
3. Ensure you have flash messages in app/views/layouts/application.html.erb.
For example:
<p class="notice"><%= notice %></p>
<p class="alert"><%= alert %></p>
4. If you are deploying on Heroku with Rails 3.2 only, you may want to set:
config.assets.initialize_on_precompile = false
On config/application.rb forcing your application to not access the DB
or load models when precompiling your assets.
5. You can copy Devise views (for customization) to your app by running:
rails g devise:views
===============================================================================
martin@martins-mba:~/myapp$ rails g devise User
invoke active_record
create db/migrate/20140212190200_devise_create_users.rb
create app/models/user.rb
invoke test_unit
create test/models/user_test.rb
create test/fixtures/users.yml
insert app/models/user.rb
route devise_for :users
martin@martins-mba:~/myapp$ rake db:migrate
== DeviseCreateUsers: migrating ==============================================
-- create_table(:users)
-> 0.0505s
-- add_index(:users, :email, {:unique=>true})
-> 0.0019s
-- add_index(:users, :reset_password_token, {:unique=>true})
-> 0.0009s
== DeviseCreateUsers: migrated (0.0538s) =====================================
問題好像就解決了！
