TypeError: tree.cleanup is not a function

TypeError: tree.cleanup is not a function

[joliss]

Hm, I can't reproduce this with the following Brocfile.js - it builds fine:

var broccoliSource = require('broccoli-source');
var src = new broccoliSource.WatchedDir('src');
module.exports = src;

Can you dig some more to narrow down the problem?

Yes, I was digging more into it and it seems that at some point, I broke Broccoli as the whole. So it's not related to broccoli-source. And then, I saw your comment. And I understood. I reduced my file so much that I didn't even have a module.exports. This is what cause the break... Yes, you can blame me. Anyway, I take the opportunity to thank you for Broccoli (you're one of the main dev, right?) and please excuse me for the noise.

hello.
I came to your problem, how do I solve this issue ?

[woshilapin]

As explained above, do you have module.exports statement in your file?

[MahnazSheikhi]

This is the file I used
-------------------------------------- Brocfile.js---------------------
var tree = './app';
var ES6Modules = require('broccoli-es6modules');
var amdFiles = new ES6Modules(tree, {
format: 'amd',
bundleOptions: {
entry: 'app.js',
name: 'amdApp'
}

});

I realized due to the link below : module.exports is the object that's actually returned as the result of a require call. by

but I cleaned all the lines ,The same problem came again.
