rails gem Simple_form installation is not working

I am using rails 4.2.4 and I am trying to use simple_form

Right now my view gives the error:

undefined method `simple_form_for' for #<#<Class:0xbbc2748>:0xbbc1460>

Gem list returns a list of gems and it includes simple_form. I installed simple_form by typing gem install simple_form

$gem list

returns

simple_form (3.2.1)

I have also tried and got this:

rails generate simple_form:install --bootstrap
Could not find generator 'simple_form:install'. Maybe you meant 'responders:install', 'rspec:install' or 'devise:install'
Run `rails generate --help` for more options.

Does anyone know how to fix this issue?

Solution

  • If you just installed it via gem install you didn't add it to your Rails application. Instead, you need to add it to your Gemfile, look at the documentation.

    Gemfile:

    gem 'simple_form'

    Then run bundle install and continue with the installation from the Github page.
