Cannot build simple rake task

Question

I created a task lib/tasks/initiate.rake with the code

namespace :initiate do
  desc "initiate bundle install"
  task :initiate do
    `bundle install`
  end
end

And I keep getting the following response:

$ rake initiate
warning: parser/current is loading parser/ruby22, which recognizes
warning: 2.2.3-compliant syntax, but you are running 2.2.1.
rake aborted!
Don't know how to build task 'initiate'

(See full trace by running task with --trace)

What's going on?

Answer 1

You have to use rake <namespace>:<task> .

In your case that would be rake initiate:initiate

Answer 2

You can run:

rake -T | grep initiate

To find out the proper namespace plus name you should be using to run that task.
