我想在RubyonRails中创建数据库

这在开发环境中运行良好

但上传AWS lightsail时，出现了此错误

有什么问题吗

下面使用gem

source 'https://rubygems.org'

gem 'kaminari'
gem 'faker'
gem 'carrierwave'
gem 'fog-aws'
gem 'mini_magick'
gem 'devise'
gem 'sunspot_rails'
gem "bootstrap_form", ">= 4.0.0.alpha1"
gem 'rails', '5.0.6'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
gem 'figaro'
gem 'sunspot_solr'
gem 'sqlite3'

group :development, :test do
  gem 'byebug'
end

group :development do
  gem 'web-console', '~> 2.0'
  gem 'spring'

end

下面创建控制器

def create
    @person = Person.new(params.require(:person).permit(:name, :phone, :relation, :user_id, :image))

    if @person.save
        redirect_to people_path
    else
        redirect_to new_person_path
    end
end

下面是new.html.erb

<body class="main4">
<div class="container" style = "letter-spacing:-1px;">
    <center><h2 class="mt-5">연락처 추가</h2></center>
    <div style="font-weight: bold; display:flex; justify-content:center; margin-top: 10px; letter-spacing:-1px;">

        <%= f.hidden_field :user_id, value: current_user.id %>


        <p style="text-align:right;"><%= f.button :추가, label: '추가', :class => 'btn btn-outline-light' %></p>

下面是lightsail中的错误场景

同样，它在开发环境中工作，但是如果您将它放在AWS lightsail上，我会发现此错误

请检查日志并发布错误。我如何才能使用lightsail web仪表板中提供的私钥将AWS lightsail？SSH登录到计算机中。此问题已解决。感谢您的回答
