Ruby

Give the ruby code in issue.rb is:

begin require 'uri' require 'net/http' p ::File.exist?('/tmp/tomcat-8/v8.0.39/bin/apache-tomcat-8.0.39.tar.gz.md5') uri = URI( 'file:/tmp/tomcat-8/v8.0.39/bin/apache-tomcat-8.0.39.tar.gz.md5' ) req= Net::HTTP.new(uri.host, uri.port) req.get( uri ) rescue => e p e.inspect p e.backtrace end 

Then the results is

true "#<TypeError: can't dup NilClass>" ["/opt/chef/embedded/lib/ruby/2.3.0/net/http/generic_request.rb:18:in `dup'", "/opt/chef/embedded/lib/ruby/2.3.0/net/http/generic_request.rb:18:in `initialize'", "/opt/chef/embedded/lib/ruby/2.3.0/net/http/request.rb:15:in `initialize'", "/opt/chef/embedded/lib/ruby/2.3.0/net/http.rb:1156:in `new'", "/opt/chef/embedded/lib/ruby/2.3.0/net/http.rb:1156:in `get'", "/tmp/issue.rb:7:in `<main>'"]
