ruby rake utility on the command line

Question

So I am very new to Ruby, but I have written a few rake files to get the hang of things, and they worked perfectly well. Fast forward through a vacation, and now I can't get them to run at all, even the most basic rake file that only contains a 'put'

I am only running the rake utility on the command line, in the same directory as my rake file, yet I am dogged by a 'No Rakefile found' error.

My Internet research repeatedly says to make sure you're in your application directory, but as far as I can tell, I have not made an app.

C:\Users\me\.rake>rake mytask --trace
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)

Thanks.

Answer 1

your rakefile needs to be named one of these: rakefile, Rakefile, rakefile.rb, Rakefile.rb or you need to pass rake the -f flag and specify a file like this:

rake -f my_awesome_rakefile.rb

so heres a tutorial:

create a file named my_awesome_rakefile.rb and fill it with:

task :check_awesomeness do
  puts "still awesome!"
end

now run rake -f my_awesome_rakefile.rb check_awesomeness from the same directory as my_awesome_rakefile.rb and check if it's still awesome.

or you could rename the file to rakefile and rename the task to default and just run rake by itself.
