Issues with Gem bundle

When I open up a project folder in my terminal I get:

Gemfile Gemfile.lock README.md lib spec

When I run “cat Gemfile” I get:

frozen_string_literal: true

source “https://rubygems.org

gem “rspec”

I already installed “gem install bundler pry byebug”

I don’t know how to fix this issue. If you could help me out that would be great!
