Cannot use Ruby gems

[Jonas Everraert]

I am unable to require Ruby gems on my server. My hosting provider also has no idea as to why this happens.

Here's a minimal example:

$ ruby -r 'sinatra' my_script.rb
/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- sinatra (LoadError)
        from /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require'

I have tried adding the following in my bashrc:

export GEM_PATH=$GEM_PATH:/home/k16461ks/ruby/gems/gems/:/opt/cpanel/ea-ruby27/root/usr/share/gems/gems/

With no succes.

Is there anything I am missing?

Hey there! When setting up a Ruby application on a cPanel server using the following guide:

How to Create a Sinatra Ruby Application | cPanel & WHM Documentation

This document describes how to install a Sinatra web application.

docs.cpanel.net

I don't see the "/usr/share/rubygems" path created on the server. Can you let me know more details about how you setup the application?

Yes.

- I added `source /opt/cpanel/ea-ruby27/enable` to the bashrc like described in the link you send.
- I created the application's directory path
- I added two files in the directory:
app.rb:

require 'rubygems'
require 'sinatra'

class MailingManager < Sinatra::Base
  get '/' do
    'Hello world'
  end
end

config.ru:

require_relative "app.rb"

run MailingManager

- I then went to the Applicaton Manager, selected the correct path and deployed the app.
- I saw the following in the error log:

[ E 2022-12-29 18:29:42.9915 21334/T23 age/Cor/App/Implementation.cpp:221 ]: Could not spawn process for application /home/k16461ks/mailinglijsten/project_src: The application encountered the following error: cannot load such file -- sinatra (LoadError)

- I then went to the terminal and tried ruby -r 'sinatra' my_script.rb as described above.

The gems are installed according to the Ruby Gems screen in CPanel:

Well that sounds like it should just work at that point. Could you create a ticket with our team so we can check this out directly on that system?
