Migrations are pending; run 'bin/rake db:migrate RAILS_ENV=development' to resolve this issue.

I suggest rather download project files and try again. In Gemfile of project files, its rails version

gem 'rails', '3.2.6'

(I think rails course soon will be updated) And you may find out more by the button on your question above or link.

Try again? From what point? This is the second time that I have started over with "Build a Simple Ruby on Rails Application." The word "Simple" is a bit misleading. You think this course will be updated soon? When? I have spent more time trying to rectify errors than I have working on the actual project. I am starting over from the beginning of this track... for the third time. Jason Seifer & Jim Hoskins

Well.. I agree that ruby related info gets easily outdated (probably more than other subjects) but in case we follow along this video, I simply tried to suggest as a first thing - look up your Gemfile and rails version.

I appreciate your help kang kyu lee. I downloaded the projects files again, and the Gemfile contains (gem 'rails', '4.0.1') not (gem 'rails', '3.2.6'), and I am running ruby version 2.0.0 p353.

What now?

I just now tried myself and what I did...

• download https://s3.amazonaws.com/treehouse-code-samples/treebook-stage-3.zip and unzip (as ~/treebook-stage-3 directory)

~/treebook-stage-3$ subl .
~/treebook-stage-3$ ruby -v
~/treebook-stage-3$ rbenv global 1.9.3-p547 
~/treebook-stage-3$ rails -v
~/treebook-stage-3$ gem install bundler --no-ri --no-rdoc
~/treebook-stage-3$ bundle
~/treebook-stage-3$ rails -v
Rails 3.2.6
~/treebook-stage-3$ ruby -v
ruby 1.9.3p547
~/treebook-stage-3$ rake db:migrate
~/treebook-stage-3$ rake routes
~/treebook-stage-3$ rails server

and then opened http://localhost:3000/users/sign_up in the browser. (and it didn't show the error mentioned in your post) just in case, Gemfile in the folder looks like this (and rails in it was 3.2.6) :

source 'https://rubygems.org'

gem 'rails', '3.2.6'

gem 'sqlite3'
gem 'devise'

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

How do I downgrade to ruby 1.9.3 p547 ? I am running ruby version 2.0.0 p353, and I tried reverting to an older version without any success.

Now I see "ActiveRecord::StatementInvalid in StatusesController#index" when I open the web browser with localhost:3000. I have only exacerbated the problem. I would really like to finish this part of the track some time this month... This is ridiculous.

Here is what I have: rails -v Rails 3.2.6 ruby -v Ruby 1.9.3p545

Great you found out about ruby versions and it seems almost there.. and now something wrong with a statement in index method of StatusesController. I am not so sure but seems like.. did you rake db:migrate?

or.. it can be some other parts. Good luck!
