r.js throws an error every time I try to assign a variable in Coffee-Script - coffeescript

Question

So I'm using r.js to build a bunch of my files -- some of which are Coffee-Script. I am using the Require plugin require-cs to handle this.
Here is a look at my Require.js config, a la rjs:
rjs.optimize({
baseUrl: SRC_PATH,
include: channelMap[channel],
optimize: 'none',
stubModules: ['cs', 'tpl', 'less', 'text'],
exclude: ['normalize', 'coffee-script', 'underscore'],
CoffeeScript: {
header: false,
// since we use AMD, there's no need for IIFE
bare: true
},
separateCSS: true,
skipModuleInsertion: true,
// If something needs to be present for tests too and not only for
// the build step, then add it tools/karma-amd.js instead
paths: _.extend({
'less-builder': 'vendor/require-less/less-builder',
'normalize': 'vendor/require-less/normalize'
}, rjsPaths),
wrap: true,
less: {
paths: [path.join(BASE_SHOP_FOLDER, 'static', 'zalando', 'css', channel)]
},
out: path.join(BUILD_PATH, channel, BUILD_BASE_FILE_NAME + '.js')
}, function () {
// this needs to be async because less builder uses
// process.nextTick() to write the file
process.nextTick(done);
});
Even the most simple .coffee file seems to fail violently. E.g.
define [], ->
foo = "hello world"
return foo
throws the following error:
the variable "foo" can't be assigned with undefined because it has not been declared before
foo = "hello world"
^^^
When I use replace require-cs's coffee-script.js with the older version of 1.6.3 everything works just fine.

Answer 1

Your code compiles BTW. Try to go to CoffeeScriptDahWebSite and click on TRY COFFEESCRIPT and you will see that it is valid code.
From the define [], () -> code ..., I assume you are using the CoffeeScript plugin with require.js. I am ready to bet your issue is in the require.js configuration (which should be your main.js file or whatever you named it) since the error you get looks oddly like the JavaScript interpreter trying to run the invalid code you wrote (for JavaScript that is :). Meaning, your plugin is not there at all.
If you give me your require configuration maybe I can edit this answer and help you more.
Cheers!
EDIT
I see you edited your question, but you provided me the wrong file. What you showed me was the r.js optimizer configuration, instead of the main.js which specifies how cs.js and coffee-script.js files are loaded. The error might be in your optimizer, but I can't know without seeing your other config.
A reiteration of that, show me the entry point of your program, the data-main that is loaded in your HTML.

I was unable to recreate the issue:
$ cat ./etc/temp1.coffee
define [], ->
foo = "hello world"
return foo
$ coffee --version
CoffeeScript version 1.7.1
$ which coffee
/home/dev/.nvm/v0.10.23/bin/coffee
$ coffee -cp ./etc/temp1.coffee
// Generated by CoffeeScript 1.7.1
(function() {
define([], function() {
var foo;
foo = "hello world";
return foo;
});
}).call(this);
$ coffee -cpb ./etc/temp1.coffee
// Generated by CoffeeScript 1.7.1
define([], function() {
var foo;
foo = "hello world";
return foo;
});

Turns out the problem was with my previous version of 1.7.1. Someone Beautified it and broke everything. Everything works as advertised when I go out of my way to get coffee-script.js from http://coffeescript.org/extras/coffee-script.js
