migration problem

Hello,

I have this migration file :

class CreateUsers < ActiveRecord::Migration
def change
create_table :users do |t|
t.string :name
t.string :email

t.timestamps null: false
end
end
end

but as soon as I do rake db:migrate I see this errors appear:

bundle exec rake db:migrate
== 20141130204806 CreateUsers: migrating ======================================
– create_table(:users)
-> 0.0279s
== 20141130204806 CreateUsers: migrated (0.0281s) =============================

rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

The first thing I would do is drop back to a released version of ruby
rather than a beta version. That is 4.1.8 I think. It may not be the
problem but I would try it first.

Also what version of rubygems are you using?
gem -v

I just encountered this issue as well. This is due to an update in Arel. You should be able to solve it by adding an explicit version requirement to your Gemfile or drop back to a stable rails version as mentioned.

gem ‘arel’, ‘6.0.0.beta2’

Thanks, that did the trick.

I use the beta versions because on the online tutorial from Hartl that versions are mentioned and he says not to use any other version to follow the tutorial.
