Cannot load such file error

[computer990784]

Sorry, but I've never done any coding so this might just be a dumb and ignorant question. But after running the command in my game folder, it ended up like this:

PS E:\Test> ruby to_json2.rb <internal:C:/Ruby32-x64/lib/ruby/3.2.0/rubygems/core_ext/kernel_require.rb>:85:in require': cannot load such file -- jsonable (LoadError) Did you mean? json/add/set from <internal:C:/Ruby32-x64/lib/ruby/3.2.0/rubygems/core_ext/kernel_require.rb>:85:inrequire' from to_json2.rb:8:in `

' PS E:\Test>

What did I do wrong here?

You probably do not have Jsonable installed: https://github.com/treeder/jsonable This project may be rewritten for Ruby 3.x.
