You’ll need to install ruby version 2.7.1 on your machine to proceed.
Alternatively, you could change the ‘ruby-version’ specified in the Gemfile to match what you have (2.3.3). That’s a pretty major change and it’s possible the project will not work with such an old version.
Are you using a ruby-version manager? Where did this
Gemfile
come from?If this is because you did
rails new
to start a new rails project, it’s likely that you’ll want to run with a ruby version that’s more modern than 2.3.3 which means (as I said on the first line), you’ll need to upgrade your system’s default ruby.I thought that you could follow this tutorial https://medium.com/ruby-on-rails-web-application-development/how-to-install-rubyonrails-on-windows-7-8-10-complete-tutorial-2017-fc95720ee059, when you get ruby 2.7.1 you could start ok with no problem.
