我真的被这个教程困住了，并且一直在慢慢地把它拉回原形。（我是 2 周的新手）。当我跑

bundle exec rspec spec/requests/user_pages_spec.rb -e "edit page"

我明白了

sis-macbook-pro:sample_app Lagaspi$ bundle exec rspec spec/requests/user_pages_spec.rb -e "edit page"
Run options: include {:full_description=>/(?-mix:edit\ page)/}

这是我的 /spec/requests/user_pages_spec.rb

有任何想法吗？

users_controller.rb

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
end

您的问题似乎是您没有编辑操作。添加这个

def edit
    @user = User.find(params[:id])
end

到您的用户控制器。
