How to upgrade and publish the next version of your ruby gem?

If you are already built a gem and want to release its next version then follow the bellow mentioned steps :-

1. Update the version in your version.rb file
   

   module HashMultiTool
     VERSION = "0.1.5"
   end
   
   

2. Run this command inside your gem directory
   

   gem build your_gem_name.gemspec
   

   
   In my case it is -
   

   gem build hash_multi_tool.gemspec
   
   

3. It will generate a .gem file with the specified version. In my case it looks like this -
   

   hash_multi_tool-0.1.5.gem
   
   

4. Now its time to push our new version to rubygems.org -
   

   gem push  hash_multi_tool-0.1.5.gem
   
   

5. Output will be something like this -
   

Check it on rubygems.org -
