Rails：生成带有bootstrap-sass集成的simple_form 3.4.0

Question

I am new to rails and in order to do the task I tried the command

rails generate simple_form:install --bootstrap

as was recommended, but end up having errors, which are-

Running via Spring preloader in process 1006
Expected string default value for '--test-framework'; got false (boolean)
Expected string default value for '--jbuilder'; got true (boolean)
Expected string default value for '--test-framework'; got false (boolean)

Could not find generator 'simple_form:install'.
Maybe you meant 'integration_test', 'scaffold' or 'active_record:model'
Run `rails generate --help` for more options.

Can anyone help me figure out what has gone wrong and what I must do?

I have installed the gems simple_form(3.4.0) and bootstrap-sass(3.3.7) using the commands

 gem install simple_form
 gem install bootstrap-sass
 bundle install

Answer 1

You have to put simple_form and bootstrap-sass into your Gemfile before runnign bundle install . If the problem persists, please do post your Gemfile for clarification.

Answer 2

Put this two line in gemfile as below...

gem 'simple_form'
gem 'bootstrap-sass'

then fire command bundle install
