When it comes to generating the pdf using the prawn gem, 2 requires are done: require 'prawn' & require 'prawn-table'
The result is:
require': cannot load such file -- prawn-table (LoadError)
For some reason, the prawn-table gem cannot be loaded. Why not?
The gems exist in the gem env path (see below):

require 'prawn' require 'prawn/measurement_extensions' require 'prawn-table' def generate_pdf(invoice, mode) Prawn::Document.generate(invoice.file, margin_top: 0, page_size: 'A4', info: {... which results in:
