Please help fix this problem

Also when I try require spreadsheet I get the same error

require 'spreadsheet'

But this module was install

$ gem list | grep spreadsheet
spreadsheet (0.9.2)

Answer 1

Try to fix version of "spreadsheet" gem to "0.9.0".

In my case adding

gem "spreadsheet", "0.9.0"

right before roo gem made a trick.
