I am trying to setup a Rake Task (without rails), and thus created a demo Hello World Task. However, upon running rake -T or rake --tasks nothing is returned, as if the task hasn't been identified. What am I doing wrong here?
Also When I run rake hello_world I get the following error:
➜ ~/GitHub/Cerner/test git:(master) ✗ rake hello_world
rake aborted!
Don't know how to build task 'hello_world' (See the list of available tasks with `rake --tasks`)

[Update] The rakefile:
# frozen_string_literal: true
# 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.
$LOAD_PATH.push File.expand_path('lib', __dir__)

I've created an app using Ruby on Rails and Spree.
After changing my SQlite database to PostgreSQL I needed to migrate my database.
But when I try to run rake db:migrate, rake db:migrate RAILS_ENV=development, bin/rake db:migrate RAILS_ENV=development I get the same error.
rake aborted!

When I run --trace I get the following response

Could not load dummy application. Please ensure you have run `bundle exec rake test_app`
** Execute default
Does any of you know what the cause of the problem is and what I should do?
Rakefile
require 'rubygems'
require 'rake'
require 'rake/testtask'
require 'rspec/core/rake_task'
require 'spree/testing_support/common_rake'
RSpec::Core::RakeTask.new
task default: :spec
desc "Generates a dummy app for testing"
task :test_app do
ENV['LIB_NAME'] = 'spree/frontend'
Rake::Task['common:test_app'].invoke
end
I added,
require File.expand_path('../config/application', __FILE__)
and
YouApp::Application.load_tasks
to my rake file.

I created a Rails 4 app recently and for some reason my rake tasks don't include test. Here's some console action to demonstrate the problem:

Any idea why this is the case, and what I can do to fix it?
Take a look into config/application.rb whether the testing framework is actually required there. At the very top, there should be
require "rails/all"
Depending on your setup, you might have each individual component required separately. Make sure that test_unit is among them.
require "rails/test_unit/railtie"
When I run heroku run rake db:migrate, I receive the following error:

Other users have posted identical errors, but in their case they actually didn't have a Rakefile and it worked for them once they created one, or they were in the wrong directory. My app does have a Rakefile, in the correct directory and with all the proper text in it, and I am in my app's root directory.
This is what my Rakefile looks like:
# 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__)
Rails.application.load_tasks
This is what "heroku run cat Rakefile" does:
$ heroku run cat Rakefile
Running `cat Rakefile` attached to terminal... up, run.9132
cat: Rakefile: No such file or directory
Whenever you are struggling with Heroku you should check your logs:
heroku logs
Scan through for any errors that you can google and/or get hints to what is going wrong.
If you are using git you can quickly search for errors with this:
git grep "whatever you want to search for"
You will then know where to find the file so you might try to verify that the rakefile actually exists with:
git grep rakefile
Sometimes it is easier to just start fresh and reset your database and reload your current schema with:
rake db:reset db:migrate all
This will destroy your db and then create it and then migrate your current schema:
rake db:drop db:create db:migrate
If you want to reset the heroku db
To drop the database, if you are using SHARED_DATABASE_URL:
heroku pg:reset DATABASE
To recreate the database with nothing in it:
heroku run rake db:migrate
To populate the database with your seed data:
heroku run rake db:seed
I upgrade my app from rails2 to rails3. Now every time I run a task I get this error:

I don't know why is loading something about Test Unit if I'm using Rspec. I tried change rake version, changing the require 'rails/all' but none fixed this issue.
But my tasks are loaded, so seems this is kind of a warning. But I'd to know how to fix this.
Update 1
These errors only appear when my task interact with Model/Controllers.
My Rakefile:
require File.expand_path('../config/application', __FILE__)
require 'rake'
CIMM::Application.load_tasks
Check your Rakefile. it probably loading TestUnit
You should show the custom task if you want more help.

*I want to get a custom Rake task to run in my Sinatra app but I keep getting rake aborted!
Don't know how to build task 'greet'.
Here's the custom Rake task (greet.rake) for testing purpose:
task :greet do
puts "Hello!"
end
I've put the greet.rake in ./lib/tasks (Rails). I'm guessing Rake can't find the correct directory for the file.
How do I get a custom Rake task to run in Sinatra?
I'm using Ruby 2.0.0 and Sinatra 1.4.4.
UPDATE
The Rakefile now looks like this:
require "./app"
require "sinatra/activerecord/rake"
require "./lib/tasks"
When using:
rake greet
I get:
rake aborted!
cannot load such file -- ./lib/tasks

(See full trace by running task with --trace)
Create a Rakefile at your Sinatra app's top directory, require the file that contains this task you want to use and you should be good to go.
Edit:
A simple solution is changing your Rakefile to:
require "./app"
require "sinatra/activerecord/rake"
Dir.glob('lib/tasks/*.rake').each { |r| load r}
Now any .rake file under lib/tasks will be loaded.
