Syntax Error??

I wanted to make a 'simple blog' refer to "Creating a weblog in 15
minutes" on rubyonrails.org

I made controller named post, and model named posts and started again
Webrick server
but , ther was a error like this ->

SyntaxError

app/controllers/posts_controller.rb:1: Invalid char `\357' in
expression
app/controllers/posts_controller.rb:1: Invalid char `\273' in
expression
app/controllers/posts_controller.rb:1: Invalid char `\277' in
expression

RAILS_ROOT: script/../config/..

This error occured while loading the following files:
   script/../config/../app/controllers/posts_controller.rb

I wonder why this error is occuring..

P.S It's my first writing in this group :slight_smile:
