I am going through a tutorial and have an issue with rake db:migrate and my gemfile. I KNOW there are several answers, and this question is asked (and answered a lot) here. But for some reason, I am either running in circles, confused or maybe something else is going on that I'm not aware of.
I've tried the answer referenced here -- where I ran
bundle exec run rake -T
That did not seem to work.
Then I tried to follow dhh's advice referenced here, but my system is saying that I don't have the gemfile to uninstall. Here is what I did:
Z-Kidds-MacBook-Air:demo_app zkidd$ rake --version
rake, version 0.9.2.2
Z-Kidds-MacBook-Air:demo_app zkidd$ gem uninstall rake -v=0.9.2.2
INFO: gem "rake" is not installed
Z-Kidds-MacBook-Air:demo_app zkidd$
Anyways, here is the read-out when I run trace:
Z-Kidds-MacBook-Air:demo_app zkidd$ rake db:migrate --trace
rake aborted!
You have already activated rake 0.9.2.2, but your Gemfile requires rake 0.8.7. Using bundle exec may solve this.

I also tried to modify my Gemfile by adding

But then I get this:

And I am running:
Rails 3.0.1
In your Gemfile, set the version for rake to from 0.8.7 to 0.9.2.2:
gem "rake", "0.9.2.2"
Then run your update:
bundle update
I actually just solved this issue earlier today in one of my own projects.

I am experiencing an error with running the Rake command. When I try to Rake in my Rails project, I get an error that says Could not find rake-10.1.1 in any of the sources.
I put Rake 10.1.1 in my Gemfile, but it appears to do nothing when I bundle install.
I've tried uninstalling then installing the Rake gem in my computer's Ruby, RVM Ruby-2.1.0, the RVM Ruby-2.1.0#global, and the RVM gemset that I created for the specific project. I've also tried removing the Gemfile.lock and then bundle installing.
I've tried to manually run rake out of the terminal in multiple different Ruby/gems files including RVM. It gives this error:
/Users/me/.rvm/gems/ruby-2.1.0/gems/rake-10.1.1/bin/rake ; exit;
~ me$ /Users/me/.rvm/gems/ruby-2.1.0/gems/rake-10.1.1/bin/rake ; exit;
rake aborted!
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)
I have a Rakefile in my project and have tried renaming it as well (Rakefile.rb, rakefile).
When I run Rake commands such as rake db:migrate, I get this error:

I've looked everywhere for the solution before coming here, but I could not find it. I would be appreciative if someone could give me some advice on this issue. Thank you in advance.
Looks like it it having trouble finding dependencies. Have you installed rake on your system with gem install rake? If not you will need to use bundle exec rake.
I don't know what the problem was, but I solved it by creating a new gemset, installing Rake to it, and using it. I also switched from Rubymine to Sublime. It may have been Rubymine trying to use a different gemset. Beware of those IDE settings.
I'm following along to the excellent Michael Hartl Rails book (Rails 3.2) but am getting an error when attempting to run the command:
rake assets:precompile
The error is as follows:

Thanks for your help!
I fixed this by reverting back from p448 to p392 and then running:
rvm ruby-1.9.3-p392#global do gem install executable-hooks
as suggested by mpapis here: Rake assets:precompile cannot find ruby
I was trying to run the rake command within ubuntu and was getting ruby_executable_hooks error. I resolved it with:
rvm all do gem install executable-hooks
This seems to be an issue with 1.9.3-p448. Today I updated ruby from p392 to p448 on my server and started getting this error. I reverted back to p392 and precompilation of assets is working again.
Perhaps try installing a version before p448 and try again.
After working with this a bit more, I found that emptying and reinstalling my gems caused precompilation to start working again:
$ rvm gemset empty
$ bundle install
$ rake assets:precompile RAILS_ENV=production
I am trying to do "rake db:migrate" and it is giving me this error.

Try this bundle exec rake db:migrate
Remove rake 10.0.2 gem
By using gem uninstall rake and remove 10.0.2 version of rake gem
And Then Try rake db:migrate
Why Error comes : In you gem list two version (10.0.2 and 0.9.2.2) of rake gem install so that this error comes.*
Another Solution is you can do bundle update
For me, I just ran bundle update and everything works right again.
I was able to solve this by opening up Gemfile and changing gem 'rake', '~> 0.9.2.2' to gem 'rake', '~> 10.0.1'
In your Gemfile, explicitly set the latest rake version by:
gem 'rake', '~> 10.0.1'
And then run
$ bundle update rake
Then try
I've just ran into the same problem.
I inserted in my gemfilen gem 'rake', '~> 10.0.1' [in your case it should be '10.0.2']
I deleted my gemfile lock
I ran rake db:migration again and it worked.
I got this tip here: Activated Ruby RAKE 10.0.1, require 10.0.0
Update: In my case I didn't have rake duplicated. I just have in my gems the 10.0.1 version.
Solved the same issue by running:
bundle update
This will update your rake gem to the latest version and allow you to run the migration.
If you are using a gemset: be sure to run bundle install after you've updated rake to update your local gemset as well.
It happens because you are using rake from the system. (latest version by default)
The solution is use follow command:
bundle exec rake db:migrate
Also, you can create alias. Because this command is too big and difficult to write.
echo "alias be='bundle exec'" >> ~/.bash_profile
source ~/.bash_profile
Then you can use follow short command:
be rake db:migrate
change the version which located both in the gemfile and gemlock to the version number shown in the console, it will be done
I'm having a really frustrating issue: Rake is being dumb.
Here's how the problem comes about:
$ rails new test_app
$ rails generate scaffold new_scaffold field1:string field2:text
Both of those work just fine, but then when I do this,
$ rake db:migrate
I get the following error.

I've looked about the Internet for similar/same errors, and people have had them. Just no one ever seems to solve the problem!
How do I fix this problem?
A tweet from DHH earlier. Rake .9.0 breaks Rails and several other things, you need to:
gem "rake", "0.8.7"
in your Gemfile.
I made some research just after my previous answer (sorry, I must do before it).
All problems are solved with Rake gem 0.9.2.. I followed these steps:
I installed gem install rake -v=0.9.2 (I had the 0.9.1 gem)
removed the 0.9.1 with gem uninstall rake -v=0.9.1
updated with bundle update
then the db:migrate showed a warning, WARNING: Global access to Rake DSL methods is deprecated. Please....
It was solved by adding the following to the Rake file.
module ::YourApplicationName
class Application
include Rake::DSL
end
end
I ommited the module ::RakeFileUtils extend Rake::FileUtilsExtend option sugested by #databyte.
It means that the Rake gem 0.9.2 works fine!
Going through Chapter 2 of Railstutorial (demo_app) and ran into this problem. I tried all of the other answers listed here, but couldn't get it to work until I did this:
Put this in your Rakefile above require 'rake':
require 'rake/dsl_definition'
via How to fix the uninitialized constant Rake::DSL problem on Heroku?
I also recommitted and pushed all files to Github and Heroku.
All I needed to do was use:
gem install rake
I had version 0.9.2 already, just needed installing.
Reinstall the rake gem and it should work fine:
gem uninstall rake -v=0.9.2
gem install rake -v=0.9.2
If not, specify version '0.8.7' in your Gemfile.
If not using Bundler:
sudo gem install rake -v 0.8.7
sudo gem uninstall rake
Then choose to uninstall 0.9.0.
If like me you're stuck on rake 0.8.7, and you're using Rails 3.2.x then railties adds a requirement for Rake::DSL
To solve this, to the top of your Rakefile you should add:
module Rake
module DSL
end
end
I solved the same problem with the following steps:
In Gemfile:
gem 'rake', '0.9.2'
Then ran this on the console:
sudo bundle update rake
Then added the following lines to Rakefile:
require 'rake/dsl_definition'
include Rake::DSL
Rails 3.1.rc1 has been updated. For your own Rakefiles, you can add this before the call to load_tasks.
module ::YourApplicationName
class Application
include Rake::DSL
end
end
module ::RakeFileUtils
extend Rake::FileUtilsExt
end
https://gist.github.com/4cd2bbe68f98f2f0249f
UPDATE: Also noticed it's already answered here as well: Undefined method 'task' using Rake 0.9.0
I had the same issue and had to use the rake 0.8.7 gem instead of 0.9.0.
I am a Windows XP user and I had the same problem.
I entered gem "rake", "0.8.7" into the gemfile, and then typed the following from the command window.
bundle update rake
This fixed my problem.
Go to your project path
Type bundle install --path=vendor/bundle
Type bundle exec rake db:migrate
To start server type bundle exec rails s. Use bundle exec and you will be sure that you use right gems (required version) for your project.
Also I would recommend you to add vendor/bundle to .gitignore if you use git and make alias for bundle exec. If you use zsh you can follow this approach
Same as Branstar above - thanks Branstar!
OS: Windows Vista
Level: Completely new to Ruby on Rails
I already had Ruby 1.9.2 installed
I followed the instructions in Running Rails 3 on Windows.
All worked up until the "rake db:migrate" part which gave me the same output as original post.
I ran:
gem install rake
I ran again:
rake db:migrate
Then I was able to start the Ruby on Rails server and had everything in place.
Thanks again Branstar :-)
I feel for you (mikhailvs), it's really frustrating. I have been going crazy for almost one full day. I even uninstalled Ruby and all its dependent files and shutdown my PC, but I still got the same problem.
What I got from the error message is the problem with Rake 0.9.2. It seems like it wasn’t fully installed. So I had to reinstall gem install rake -v=0.9.2
I wasn’t sure if I have rake –v0.9.1 installed. So to make sure I’m safe I tried to remove that old version with gem uninstall rake -v=0.9.1. But is showed me the error message
ERROR: While executing gem ... (Gem::InstallError)
cannot uninstall, check `gem list -d rake`
OK, so I checked all Rake directories on my PC, and found I only had Rake 0.9.2.
Then to check if everything went alright, I migrated with rake db:migrate. And it worked :)
I think I didn’t have Rake 0.9.1 because I clean-installed Ruby (rubyinstaller-1.9.2-p180 - on my Windows 7 system) and all gems as well. In the meantime Rake 0.9.2 wasn’t fully installed.
Uninstalling with "gem uninstall rake" worked for me, I had 2 versions installed, so I jest did a clean reinstall.
"rake db:create", to make sure the database exists
and then "rake db:migrate" to seal the deal.
I had the same issue using Rake 0.9.2.2. I solved this problem by using bundle exec.
For Rails 2.3 editing lib/tasks/rspec.rake like in this commit worked for me:
https://github.com/dchelimsky/rspec-rails/pull/11/files
Install rake 0.8.7 and uninstall 0.9.2.2
$ gem install rake -v 0.8.7
$ gem uninstall rake -v 0.9.2.2
Now use
$ bundle exec rake db:migrate
i think this will help you
;)
Run
bundle exec rake db:migrate
it works for me.
I'm having a really frustrating issue: Rake is being dumb.
Here's how the problem comes about:
$ rails new test_app
$ rails generate scaffold new_scaffold field1:string field2:text

gem "rake", "0.8.7"
in your Gemfile.
I made some research just after my previous answer (sorry, I must do before it).
All problems are solved with Rake gem 0.9.2.. I followed these steps:
I installed gem install rake -v=0.9.2 (I had the 0.9.1 gem)
removed the 0.9.1 with gem uninstall rake -v=0.9.1
updated with bundle update
then the db:migrate showed a warning, WARNING: Global access to Rake DSL methods is deprecated. Please....
It was solved by adding the following to the Rake file.
module ::YourApplicationName
class Application
include Rake::DSL
end
end
I ommited the module ::RakeFileUtils extend Rake::FileUtilsExtend option sugested by #databyte.
It means that the Rake gem 0.9.2 works fine!
Going through Chapter 2 of Railstutorial (demo_app) and ran into this problem. I tried all of the other answers listed here, but couldn't get it to work until I did this:
Put this in your Rakefile above require 'rake':
require 'rake/dsl_definition'
via How to fix the uninitialized constant Rake::DSL problem on Heroku?
I also recommitted and pushed all files to Github and Heroku.
All I needed to do was use:
gem install rake
I had version 0.9.2 already, just needed installing.
Reinstall the rake gem and it should work fine:
gem uninstall rake -v=0.9.2
gem install rake -v=0.9.2
If not, specify version '0.8.7' in your Gemfile.
If not using Bundler:
sudo gem install rake -v 0.8.7
sudo gem uninstall rake
Then choose to uninstall 0.9.0.
If like me you're stuck on rake 0.8.7, and you're using Rails 3.2.x then railties adds a requirement for Rake::DSL
To solve this, to the top of your Rakefile you should add:
module Rake
module DSL
end
end
I solved the same problem with the following steps:
In Gemfile:
gem 'rake', '0.9.2'
Then ran this on the console:
sudo bundle update rake
Then added the following lines to Rakefile:
require 'rake/dsl_definition'
include Rake::DSL
Rails 3.1.rc1 has been updated. For your own Rakefiles, you can add this before the call to load_tasks.
module ::YourApplicationName
class Application
include Rake::DSL
end
end
module ::RakeFileUtils
extend Rake::FileUtilsExt
end

UPDATE: Also noticed it's already answered here as well: Undefined method 'task' using Rake 0.9.0
I had the same issue and had to use the rake 0.8.7 gem instead of 0.9.0.
I am a Windows XP user and I had the same problem.
I entered gem "rake", "0.8.7" into the gemfile, and then typed the following from the command window.
bundle update rake
This fixed my problem.
Go to your project path
Type bundle install --path=vendor/bundle
Type bundle exec rake db:migrate
To start server type bundle exec rails s. Use bundle exec and you will be sure that you use right gems (required version) for your project.
Also I would recommend you to add vendor/bundle to .gitignore if you use git and make alias for bundle exec. If you use zsh you can follow this approach
Same as Branstar above - thanks Branstar!
OS: Windows Vista
Level: Completely new to Ruby on Rails
I already had Ruby 1.9.2 installed
I followed the instructions in Running Rails 3 on Windows.
All worked up until the "rake db:migrate" part which gave me the same output as original post.
I ran:
gem install rake
I ran again:
rake db:migrate
Then I was able to start the Ruby on Rails server and had everything in place.
Thanks again Branstar :-)
I feel for you (mikhailvs), it's really frustrating. I have been going crazy for almost one full day. I even uninstalled Ruby and all its dependent files and shutdown my PC, but I still got the same problem.
What I got from the error message is the problem with Rake 0.9.2. It seems like it wasn’t fully installed. So I had to reinstall gem install rake -v=0.9.2
I wasn’t sure if I have rake –v0.9.1 installed. So to make sure I’m safe I tried to remove that old version with gem uninstall rake -v=0.9.1. But is showed me the error message
ERROR: While executing gem ... (Gem::InstallError)
cannot uninstall, check `gem list -d rake`
OK, so I checked all Rake directories on my PC, and found I only had Rake 0.9.2.
Then to check if everything went alright, I migrated with rake db:migrate. And it worked :)
I think I didn’t have Rake 0.9.1 because I clean-installed Ruby (rubyinstaller-1.9.2-p180 - on my Windows 7 system) and all gems as well. In the meantime Rake 0.9.2 wasn’t fully installed.
Uninstalling with "gem uninstall rake" worked for me, I had 2 versions installed, so I jest did a clean reinstall.
"rake db:create", to make sure the database exists
and then "rake db:migrate" to seal the deal.
I had the same issue using Rake 0.9.2.2. I solved this problem by using bundle exec.
For Rails 2.3 editing lib/tasks/rspec.rake like in this commit worked for me:
https://github.com/dchelimsky/rspec-rails/pull/11/files
Install rake 0.8.7 and uninstall 0.9.2.2
$ gem install rake -v 0.8.7
$ gem uninstall rake -v 0.9.2.2
Now use
$ bundle exec rake db:migrate
i think this will help you
;)
Run
bundle exec rake db:migrate
it works for me.
