SyntaxError in ToppagesController#index解決

前提・実現したいこと

Rubyを用いてツイッタークローンのシステムを作っています。
投稿機能を付けるにあたってコードを記載し、動作確認を行ったところ
エラーが表示され、サーバーにアクセスが出来ませんでした。

プログラミングを未経験から始めてまだまもなくToppagesController#index において構文のエラーがあるといわれているのでしょうが、これを作成する基となる教本と見比べてもわからないのでこちらでご質問させてもらいます。

教えて頂けるとありがたいです。

宜しくお願いします。

試したこと

投稿機能作成にあたってのコードを全て確認をしました。

投稿機能作成時のコードです。

<ul class="list-unstyled">

<% microposts.each do |micropost| %>

  <li class="media mb-3">
    <img class="mr-2 rounded" src="
<%= gravatar_url(micropost.user, { size: 50 } %>
" alt="">
    <div class="media-body">
      <div>

<%= link_to micropost.user.name, user_path(micropost.user) %>
  <span class="text-muted">posted at
<%= micropost.created_at %>
</span>
      </div>
      <div>
      <p>
<%= micropost.content %>
</p>
      </div>
    </div>
  </li>

<% end %>

<%= paginate microposts %>

</ul>

class CreateMicroposts < ActiveRecord::Migration[5.2]
  def change
    create_table :microposts do |t|
      t.string :content
      t.references :user, foreign_key: true

      t.timestamps
    end
  end
end

class Micropost < ApplicationRecord
  belongs_to :user

  validates :content, presence: true, length: { maximum: 255 }
end

Rails.application.routes.draw do
  # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
  root to: 'toppages#index'

  get 'login', to: 'sessions#new'
  post 'login', to: 'sessions#create'
  delete 'logout', to: 'sessions#destroy'

  get 'signup', to: 'users#new'
  resources :users, only: [:index, :show, :new, :create]

  resources :microposts, only: [:create, :destroy]
end
