I'm running rackup config.ru.
The config.ru file contains:
require 'sinatra'
require 'sinatra/base'
app = ->(env){
status = 200
headers = {"content-type" => "text/html"}
body = ["<Html><Body><H1>Hello, World!</H1></Body></Html>"]
[status, headers, body]
}
run app
Which returns:
Exception `LoadError' at /Users/konstantinosschoinas/.rvm/gems/ruby-2.6.3/gems/sinatra-base-1.0/lib/sinatra/showexceptions.rb:1 - cannot load such file -- rack/showexceptions

Exception `LoadError' at /Users/konstantinosschoinas/.rvm/gems/ruby-2.6.3/bin/rackup:23 - cannot load such file -- rack/showexceptions
Also my gem env output is:
RubyGems Environment:
- RUBYGEMS VERSION: 2.6.3
- RUBY VERSION: 2.6.3 (2019-04-16 patchlevel 62) [x86_64-darwin18]
- INSTALLATION DIRECTORY: /Users/konstantinosschoinas/.rvm/gems/ruby-2.6.3
I installed Sinatra and Sinatra::Base with gem.
What am I doing wrong?
You need to update the Sinatra gem to sinatra-2.0.7.
Run:
$ gem install sinatra -v 2.0.7
