Error: undefined method `each' for nil:NilClass (NoMethodError) when trying to use

[DrogaMleczna]

When I'm trying to execute the prgram I get the following error:

C:/Users/{My username}/Desktop/lmp-master/lmp-master/lib/lmp/analysis.rb:19:in `report': undefined method `each' for nil:NilClass (NoMethodError)

  @analyses.each { |a| a.report(filename_root) }
