I am trying to run rake db:migrate in my Ruby on Rails application.
However, it is giving me a "uninitialized constant" exception. From Googling this, it looks like the solution is to update the rake version. So I changed my gemfile and ran bundle update.
However, the exception is still happening... I think because I didn't update the right rake library.
How do I fix this? How can I update rake for the other path too, or exclusively run rake through the bundle thing?

Try this command:
bundle exec rake db:migrate
bundle exec executes a command in the context of your gemfile.

I've already seen some different answers, but none of these helped me...
This is the trick: I have to fix this without touching the Gemfile. I'm currently creating my working environment so that it matches the production server, so, I cannot modify the rails' code at all.
My OS: OSX 10.11
Ruby: ruby 2.0.0p643
Rails: 4.0.0
The gem is the Gemfile as gem 'mysql2'. There are no errors when doing bundle install, but when I try to rake db:migrate --trace this is the output:
rake aborted!
There was an error while trying to load the gem 'mysql2'.

I don't know how to interpret this. Is there something wrong with the Rakefile?
Also, this is the output from the mkmf.log
EDIT: This is the content of my Rakefile, located at myapp/folder
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.
require File.expand_path('../config/application', __FILE__)
MyApp::Application.load_tasks
Try
bundle exec rake db:migrate
This will make sure that you are executing "rake db:migrate" with the gems listed in the Gemfile loaded and available. If you run it without "bundle exec" you may be executing only with the system gems available.
I met the problem 'uninitialized constant Rake::DSL'.
I have tried to add gem 'rake','0.8.7' in the Gemfile, but it didn't work out. Are there any other way to fix the problem? Thank you!

This is probably horribly bad form, but adding this to the top of my Rakefile worked for me:
module Rake
module DSL
end
end
Check your gemfile.lock, it must be having a version of rake which is > 0.8.7. If yes then delete all then delete all the instance of the version or delete all the content of gemfile.lock and then do bundle install again.
You can also try to run
bundle exec rake db:migrate
Anyone could help me?
I searched the same problem, but I can't figure out a solution still.
I ran successfully with "bundle update" "bundle install" but when running "rake db:migrate" I got the following problem...

Put this in your Rakefile above require 'rake':
require 'rake/dsl_definition'
OR if the above solution does not work,
write this in your gemfile for rake
gem "rake", "0.8.7"
and go to command prompt and write.
gem uninstall rake
This will uninstall the existing rake gem.
Then type bundle update in your project folder which will install rake 9.8.7 again.
And enjoy rails :).

This error means that Rails.application isn't initialized. I didn't actually know that, I
cheated.
So that then begs the question: how did you set up this application?
Perhaps this application doesn't contain a config/application.rb file that defines a class that inherits from Rails::Application and therefore is causing this problem. In my application here, I've got this one you could use as an example.
When running rake db:create or rake db:migrate locally my app successfully builds the tables as expected. When running on heroku however (eg. heroku rake db:migrate --trace --app ) it is giving me the following error all of a sudden:
C:\>heroku rake db:migrate --trace --app foo rake aborted!

Looking at the Rakefile this is all that's present:
require File.expand_path('../config/application', __FILE__)
require 'rake'
Foo::Application.load_tasks
The load_tasks line is line 7. I'm really not sure what changed but something sure has. Has anyone had experience with this error?
See that
There's an issue with Rake 0.9.0. Use 0.8.7 in your Gemfile for now.
