    Hi,
    I am trying to install ruby on windows but i get this error

    ERROR:  Loading command: install (ArgumentError)
            unknown encoding name - CP720
    ERROR:  While executing gem ... (NoMethodError)
        undefined method `invoke_with_build_args' for nil:NilClass

    Here is what I did

    • Install laragon ruby
    • added php mysql nginx etc. for my other development purposes
    • make new folder in root
    • run this command gem install rails
      And I got error above.

    Then

    I thought maybe ruby doesn't come with laragon so I installed rubyInstaller and tried again.
    And again I got same error.

    As I'm reading documents https://laragon.org/rails/up_and_running.html there is only this steps:

    • download laragon ruby on rails
    • run the command
      That's all.

    Now please someone tell me what I did wrong and how I can get my ruby installed?

    Thanks.
