Answer 1

It seems that you did not include open-uri .

https://ruby-doc.org/stdlib-2.5.3/libdoc/open-uri/rdoc/OpenURI.html

Try this

require 'open-uri'

URI.parse(context.capture).open

Answer 2

URI#open is private on older Ruby versions, for example 2.2. You need to use a different method (such as the global open provided by open-uri , though this is questionable from the security standpoint) on those Rubies. Or use a newer Ruby version.
