rake db:migrate aborted due to version differences

Question

I am trying to load my rails app in localhost:3000 however I've run into a few errors related to my rake versioning.

When I launch my server with rails server and then I refresh in the browser, this error shows up in my server logs:

I am using rails version 4.0.4

I am using ruby version 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin13.0]

I am fairly new to rails so layman's terms would be greatly appreciated to help me understand the problem. I just want to get my app running and my rake configuration back on track.

Answer 1

The Problem is with the gem rake, just update this Gem with the command bundle update rake and it would solve the problem while running the Migration.

Answer 2

From you log:

PG::DuplicateColumn: ERROR: column "email" of relation "users" already exists

This mean in last migration 20140424074405 AddDeviseToUsers you try create column that already exists.

Try delete this migration. About rake also from log:

You have already activated rake 10.3.1, but your Gemfile requires rake 10.2.2. Prepending bundle exec to your command may solve this.

This mean then you run rake routes it is execute rake installed on system not in project for run inside project use bundle exec rake routes
