Troubleshooting Ruby SDK

This page explains how to identify your SDK version in the PubNub Ruby Software Development Kit (SDK).

How to find the version of your SDK

The version is contained in the VERSION constant in the Pubnub module.

Steps to access the SDK version

1. Require the pubnub gem.
2. Print the version with Pubnub::VERSION.
3. Optionally initialize the SDK and log the configuration.

1require 'pubnub'
2

3def main
4  # Display the PubNub Ruby SDK version
5  puts "PubNub Ruby SDK Version: #{Pubnub::VERSION}"
6  
7  # Optional: Initialize PubNub with the current version
8  pubnub = Pubnub.new(
9    subscribe_key: ENV.fetch('SUBSCRIBE_KEY', 'demo'), # Replace 'demo' with your Subscribe Key from the PubNub Admin Portal
10    publish_key: ENV.fetch('PUBLISH_KEY', 'demo'),     # Replace 'demo' with your Publish Key from the PubNub Admin Portal
11    user_id: 'ruby-version-demo-user'
12  )
13  
14  # Display configuration with version information
15  puts "\nPubNub Client Information:"
16  puts "- SDK Version: #{Pubnub::VERSION}"
17  puts "- User ID: #{pubnub.user_id}"
18  puts "- Subscribe Key: #{pubnub.env[:subscribe_key]}"
19  
20  # Optional: Check for version compatibility
21  # This is just an example - adjust version requirements as needed
22  version_parts = Pubnub::VERSION.split('.')
23  major_version = version_parts[0].to_i
24  minor_version = version_parts[1].to_i
25  
26  if major_version >= 5 && minor_version >= 0
27    puts "\nYou are using a compatible SDK version."
28  else
29    puts "\nWARNING: This code example may require PubNub SDK version 5.0.0 or newer."
30    puts "Please consider upgrading your PubNub Ruby SDK."
31  end
32  
33  # Clean up
34  pubnub.shutdown if pubnub
35end
