[Michael Hartl のチュートリアル][1] に従って、第 7 章の演習を行ったところ、4 つのエラーがあり、一生修正する方法がわかりません。実稼働アプリを手動でテストすると、エラーはまったく存在しません。テキストの作成に何か問題があるのか どうかはわかりませんが、完全に途方に暮れているので、ここに投稿して、私の完全な初心者が私を盲目にしていないかどうかを確認しようと思いました...助けてくれてありがとう!
表示される 4 つのエラー メッセージは次のとおりです。

views/users/show.html.erb のテンプレート コードは次のとおりです。
<% provide(:title, @user.name) %>
<div class="row">
<aside class="span4">
<section>
<h1>
<%= gravatar_for @user %>
<%= @user.name %>
</h1>
</section>
</aside>
</div>
そしてここに users_controller.rb があります
class UsersController < ApplicationController
def show
@user = User.find(params[:id])
end
def new
@user = User.new
end
def create
@user = User.new(params[:user])
if @user.save
sign_in @user
flash[:success] = "Welcome to the Sample App!"
redirect_to @user
else
render 'new'
end
end
