graceful-fs versions lower than v4 reevaluate native fs module source, which is not supported.
You should update your graceful-fs dependency to v4 or later.

Tracking issue: nodejs/node#5213.

For example, str = 'es_CLAC_B' should resolve to
lang='es'
country='CLAC_B'

Assertion Error on Windows

Getting AssertionError on Windows due to the backslashes in the Windows environment. Need to normalize the URL.

Work-around: Don't use windows :) (Still looking for another work-around)

    AssertionError: Provided start directory is not within root or one of its subdirectories.

I added the following logs to the file:

/node_modules/bundalo/node_modules/file-resolver/lib/util.js

exports.locate = function locate(name, root, start) {
    var removed, file, parent;

console.log("------------");
console.log("start:");
console.log(start);
console.log("------------");
console.log("root:");
console.log(root);
console.log("------------");
    assert(~start.indexOf(root), 'Provided start directory is not within root or one of its subdirectories.');

Output of the above logs:

------------
start:
locales\US\en
------------
root:
locales/
------------

Replicated with the Test Suite:

# resolve with a bogus locale object

Hi team. I'm using Windows 7 64 bits, and I tried to run the latest version of the Kraken's examples (i.e., i18n, Shopping Cart, and others for Kraken v1.0.1) using production mode (NODE_ENV=production), but the server always threw an 'Internal Server Error', because the compiled templates couldn't be found (.build/templates/**/*.js files).

I debugged the source code, and found a problem with the 'util.js' file (line 67). This file is used by engine-munger to resolve the templates' path, but didn't consider the OS dependency when working with slashes and backslashes (it fails on Windows platform).

The old line is: root : file.replace(name, ''),
A possible solution is: root : file.replace(path.normalize(name), ''),

Using this approach the file.replace operation works as expected.

Thanks team for the great work with KrakenJS! I enjoy it :)

If something is wrong with the locale object, for example it is an empty object {} then _locate will pass non-string arguments to path.join resulting in:

TypeError: Arguments to path.join must be strings
   at path.js:360:15
   at Array.filter (native)
   at Object.exports.join (path.js:358:36)
   at Object.proto._locate (/Users/medelman/src/krakex/kraken-examples/with.i18n/node_modules/engine-munger/node_modules/file-resolver/index.js:32:29)

Not sure if this would be considered over-protective of the module or not...
