I am getting the following error when trying to install gems:
Mohammad-Azams-MacBook-Pro:awesomecats azamsharp$ sudo rake gems:install
Password:
(in /Projects/awesomecats)
rake aborted!
Don't know how to build task 'gems:install'
(See full trace by running task with --trace)
Mohammad-Azams-MacBook-Pro:awesomecats azamsharp$
If the task isn't listed in the output of rake -T then it isn't defined and you can't run it.
Rails 3 removed this task in favor of using Gemfile and bundler as the official gem installation procedure as gems:install was often tricky to get working properly.

I recently installed Rails 3.1 and now my old Rails 3.0 app won't rake db:migrate. This is what happens when I try to run bundle exec rake db:migrate. I'm on Ubuntu with no RVM
/usr/local/lib/ruby/gems/1.9.1/gems/bundler-1.0.7/lib/bundler/shared_helpers.rb:142:in `block in cripple_rubygems': can't find executable rake (Gem::Exception)
from /usr/local/lib/ruby/gems/1.9.1/bin/rake:19:in `<main>'
When I run just rake db:migrate, it outputs:
rake aborted!
You have already activated rake 0.9.2.2, but your Gemfile requires rake 0.8.7. Consider using bundle exec.
(See full trace by running task with --trace)
which rake
/usr/local/bin/rake
Put this in your Gemfile:
gem 'rake' , '>= 0.9.2'
and run bundle update
you need to give more details in what environment you're running this:
which OS?
are you using RVM?
is this a brand new RVM setup per chance?
1) Try to run this:
gem list | rake
what output do you get?
2) If you don't see rake in the output, then do this:
gem install rake
and then try rake db:migrate again
3) If you see rake, but it still doesn't work, then do this:
which rake
what output do you get? it should look something like this:
~/.rvm/gems/ruby-1.9.2-p0/bin/rake
I am using Ruby Enterprise Edition for my project. When I check all my rake task by run the command rake -T , I got the following error message:
You have already activated rake 0.9.2.2, but your Gemfile requires rake 0.9.2. Using bundle exec may solve this.
The error message implies that I can use bundle exec to solve the problem, but I am not sure how? So, how to get rid of this error message?
------------------------------ more ---------------------------
I prefer to update my Gemfile instead of run bundle exec rake -T. But when I open my project Gemfile, I did not see rake 0.9.2 in my Gemfile, why the error message complains that I have it? Where could be the place I defined rake 0.9.2??
Run bundle exec rake -T, this ensures that the version of rake that is specified in your Gemfile is running, not another version.
Alternatively, update your Gemfile.
This is because your rake tool does not match the version written in the Gemfile.
You first need to run this command, to ensure rake 0.9.2 get installed:
bundle install
Then, you can run rake 0.9.2 with the following command:
bundle exec rake -T
The bundle thing is a nice tool to help you manage the dependency of your application. You can get more info from here.
I have been trying to run rake but it seems that ever since I updated ruby gems rake is failing.
This morning I ran:
gem update --system
And ever since, rake has been failing with the following error:
$ rake db:migrate
rake aborted!
undefined method `specifications' for "/usr/lib/ruby/gems/1.9.1":String
/home/cknadler/projects/ecommerce/Rakefile:7:in `<top (required)>'
(See full trace by running task with --trace)
I have been reading about this problem and it seems that there is a problem with rake 0.9.x that breaks rails but when I check my rake version, I am running 0.8.7:
$ rake --version
rake, version 0.8.7
I have tried uninstalling rake and reinstalling it, using bundler, etc and at this point I am pretty stuck. Thanks in advance.
Edit:
My Rakefile (located in my app root directory)
# 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__)
require 'rake'
Ecommerce::Application.load_tasks
I would suggest using the bundled binary version of rake to avoid this issue.
bundle exec rake db:migrate
If you installed your bundle using binstubs (bundle install --binstubs) then you can also use the bin version of rake which is equivalent to the bundle exec rake command:
bin/rake db:migrate
P.S: I would also recommend using RVM instead of installing Ruby using sudo for all users. This allows you to keep more modular ruby and gem installation.
You should remove rake 0.9.x (you may have 0.9.2 installed) by doing
gem uninstall rake -v=0.9.2
And then run bundle update
bundle update
Hope that helps.
I just cloned a github repo on a fresh Ubuntu machine, running sqlite3 for all environments. rake db:create says development.sqlite3 already exists. rake db:migrate says I'm missing a bunch of required gems and should run rake gems:install. rake gems:install, of course, says it Could not find table 'studies', which sounds to me like something rake db:migrate should fix.
I looked around the net and while lots of people have gotten 'could not find table' errors, they all got them from rake db:migrate, not rake gems:install. I'm suspecting it's an application-specific error, but still, any ideas would be appreciated.
PS: Ruby 1.8.7, Rails 2.3.8.
You can always install separate gems with gem install -r <gem name> or gem install -v=<gem version> -r <gem name> command, not using rake.
Is this a Rails 3 app? If so, you should run:
bundle install
Rails 3 uses Bundler instead of the rake tasks to manage gems. http://gembundler.com/
Did you try running with the trace option? Might help pin down the failing gem:
rake -t gems:install
heroku rake db:migrate
rake aborted!
no such file to load -- acts_as_ferret
(See full trace by running task with --trace)
(in /disk1/home/slugs/310513_b4b7e61_4c01/mnt)
It show this message issue. how do I fixes this?
add gem in your gem file "acts_as_ferret"
bundle install
run heroku run rake db:migrate
Add the gem act_as_ferret gem.
But seems complicated in heroku environement without ferret.
