Unable to seed database in rails tutorial

11.2.2

First I migrated db(bundle exec rake db:migrate:reset), then I try to seed it(bundle exec rake db:seed) and I get this message:

rake aborted!

Tasks: TOP => db:seed

This is mine db/seeds.rb file:

User.create!(name:  "Example User",
             email: "example@railstutorial.org",
             password:              "foobar",
             password_confirmation: "foobar",
             admin: true,
             activated: true,
             activated_at: Time.zone.now)

99.times do |n|
  name  = Faker::Name.name
  email = "example-#{n+1}@railstutorial.org"
  password = "password"
  User.create!(name:  name,
               email: email,
               password:              password,
               password_confirmation: password,
               activated: true,
               activated_at: Time.zone.now)

users = User.order(:created_at).take(6)
50.times do
  content = Faker::Lorem.sentence(5)
  users.each { |user| user.microposts.create!(content: content) }
end

Try this:

99.times do |n|
 name  = Faker::Name.name
 email = "example-#{n+1}@railstutorial.org"
 password = "password"
 User.create!(name:  name,
           email: email,
           password:              password,
           password_confirmation: password,
           activated: true,
           activated_at: Time.zone.now)
end #This is the missing end and your sytax error
