undefined local variable or method ruby

I recently bought a book that helps a beginner learn ruby. We are building our 1st program and I cannot run the script through terminal without getting an error. All i'm trying to do is open a file.

Here are the details: The script file is simply:

file.open("text.txt").each { |line| puts line }

This script is saved as analyzer.rb and saved in my ruby file called "ruby".

The text.txt file is a plain text file that has the first chapter of oliver twist, nothing special. It is also saved in the ruby file.

Here is what I am typing into terminal to simply run the script:

cd ~/ ruby
ruby analyzer.rb

Here is exactly what I get.

Hunters-MacBook-Pro:ruby huntermaxfield$ ruby analyzer.rb
analyzer.rb:2:in `<main>': undefined local variable or method `“text' for main:Object (NameError)

I have tried to manipulate the code in all sorts of ways, but since I am a beginner it really is just a guess. Any help would be great.

I encountered the same issue on page 84 (Beginning Ruby; From Novice to Professional) of Peter Cooper's book. I definitely recommend using Sublime instead of TextEdit that I initially used. It is all about using REGULAR QUOTES in the code, not smart quotes. Moreover try not to copy paste if you are not sure of your editor!

In File 'F' should be in capital. That's the mistake

File.open("text.txt").each { |line| puts line }

Also make sure "text.txt" is in same directory as you ruby script, else provide absolute path like File.open("absolute/path/to/text.txt")
