Most simple Ruby Problem Imaginable

Hi,

I’m new to Ruby and am learning with “Beginning Ruby from Novice to
Professional,” and I’ve hit a roadblock within the first few pages of
the book.

For some reason, even though I believe I am following the instructions
correctly, I keep having the same problem. I am using the author’s
first example:

class Person
attr_accessor :name, :age, :gender
end
=>nil
person_instance=person.new

Every time I attempt to create an instance of the class I receive the
“name error: undefined local variable…” error message. After
uninstalling and reinstalling various versions of Ruby I am having the
same problem. What’s going on here?

Thanks,
Jon

person_instance=person.new

person_instance=Person.new

            ^ !

Thank you so much. I had a feeling that case sensitivity was going to
bite me at some point. Sorry for your time.
Thanks again,
Jon
