It is not necessary to post the same error report 19 times.
This error comes from the fact that the Fixnum and Bignum subclasses have been removed from Ruby 3.x. Code should just test against the Integer class going forward.
A temporary solution is to define aliases to the Integer class.
If DB_WM is a module then …
module DBUR
module DB_WM
Fixnum = ::Integer
Bignum = ::Integer
end
end
But if DB_WM is a class, then:
module DBUR
class DB_WM
Fixnum = ::Integer
Bignum = ::Integer
end
end
