Installation Guidance

[johnrsnyder]

Looking ahead, I thought I would give a Windows installation a try (someone had to do it:) I was able to do the "bundle install" w/o any errors, but when I invoke the "bundle exec rake fhir:console" I get a status "127" error which generally points to something not found, I believe.

Can you please add a listing of prerequisites into the readme, or create a separate installation guide for the run-time? Consider that many will want to run the client from Windows, so it would be great to know what prerequisites are necessary to run from a Windows environment.

Can you copy and paste the exact error you're seeing the Windows Command Prompt (or whatever tool you're using)?

Tasks: TOP => fhir:console

C:\GitHub\fhir_client>

Ah. Well, the issue is Windows doesn't have a sh command:

  task :console, [] do
    sh 'bin/console'
  end

So, the short-term workaround is probably to run the program:

> .\bin\console

or possibly

> ruby .\bin\console

I say probably, because I don't have access to Windows.

[jawalonoski]

Another option, change lines 6 - 8 in ./lib/fhir_client/tasks/tasks.rake:

task :console, [] do |t, args|
    binding.pry
end

Try this and let me know if it works.

I installed Ruby on my Windows machine. I was able to fix this issue by changing the sh call to exec and adding ruby to the command. I was having trouble just doing binding.pry, and besides, we probably should call the same code we have in the bin directory.
