Zoo error: Rails - cannot load such file -- rack

19 Jun 2015, 11:46

I am currently porting a Heroku site over to IIS using HeliconZoo and it is a chore to say the least :). However, the product is quite impressive and I get the default installs to work no problem. It is when I move in the /app from the Heroku site the problems start. I updated all the gems as outlined in the gemfile, etc. and the last error I am working on now is:

DL is deprecated, please use Fiddle [tid-2772520] cannot load such file -- rack (LoadError) C:/Zoo/Workers/ruby/lib/app.rb:84:in `eval' (eval):1:in `assure_rack'
message: Application backend read Error. type: ZooException file: App\Jobs\JobBase.cpp line: 531 version: 3.1.98.

Re: Zoo error: Rails - cannot load such file -- rack

I'm not Ruby developer, but the error is in the "require 'rack'" command. Maybe rack has not been installed in your Ruby installation somehow. Please try to install it.
Also, moving other Ruby application means install "Ruby template" first, let it run and configure it as needed and then move application over it by copying files on top of template. There may be some essential files absent in your application so use template.

Also,the error is generated in one of your files C:/Zoo/Workers/ruby/zoorack.rb. What is this file for?

This file is a FastCGI worker for Ruby. You can switch your project to use HTTP with Thin or other HTTP server following instructions on "Ruby project" start page. HTTP backend connection does not require FastCGI worker and this file will not be called.

Thank you, I followed your advice and switched to http but now get this error:
