unable to run coffeescript app on nodejs. receiving exception

I have reacently started learning coffescript and was trying to fllow a simple tut. However when I try to run my app.coffee file using coffee app.coffee command, i keep on getting this exception;

PS C:\Users\Office\Workspace\node\blog-demo\coffeepress> coffee .\app.coffee
Error: In .\app.coffee, Parse error on line 1: Unexpected ' '
    at Object.parseError (C:\Users\Rishav\AppData\Roaming\npm\node_modules\coffee-script\lib\coffee-script\parser.js:477

e-script\command.js:150:18)
    at fs.readFile (fs.js:176:14)
    at Object.oncomplete (fs.js:297:15)

the coffee code is;

###
Module dependencies.
###
express = require("express")
routes = require("./routes")
http = require("http")
path = require("path")
app = express()
app.configure ->
  app.set "port", process.env.PORT or 3000
  app.set "views", __dirname + "/views"
  app.set "view engine", "jade"
  app.use express.favicon()
  app.use express.logger("dev")
  app.use express.bodyParser()
  app.use express.methodOverride()
  app.use app.router
  app.use express.static(path.join(__dirname, "public"))

app.configure "development", ->
  app.use express.errorHandler()

app.get "/", routes.index
http.createServer(app).listen app.get("port"), ->
  console.log "Express server listening on port " + app.get("port")

All my modules are the latest available till date.

Your code is absolutely fine. Coffeescript however reserves keywords like static therefore if you run coffee -c your_file.coffee you will see your compiled js in your_file.js. Open it with editor and see what is wrong.

I am betting that the line app.use express.static(path.join(__dirname, "public")) gets compiled to somthing like app.use(express["static"](path.join(__dirname,"public")). And that causes your error ;)

In future, if there is an error, compile the coffeescript first and then see the compiled version and see what is wrong with it.

I can run the code except for the routes file which you don't provide. I would try to recreate the file and see if there is anything corrupt with the actual file. I have sometimes had problem with Coffeescript files being malformed in indenting and it complains on something else.

The other thing I suspect is that there might be something wrong in your routes file.
