TypeError: undefined is not a function

[Vistritium]

when I try to build app:
nwbuild .
or run
nwbuild -r .
I get
[TypeError: undefined is not a function]
When I run in non-app folder it just says that it couldn't find package.json
I tried it on very simple app with just package.json and index.html, also tried it on another example app.
Is it possible to generate more logs so I could find more information about what is happening?
I use Windows 10

I'm getting the same error to, but I fixed the bug temporarily.
in line 161 @ version.js
error code:
var version = versions.find(function(version){...});
fixed code:
var version = _.find(versions,function(version){...});

I use Mac:)

Thanks for reporting. What's your Node version? nw-builder requires version 4 or newer.

Ignore the fact this was closed above. I don't think that fixes your problem. I think it's related to an old Node version. But try version 2.2.6 anyway and if it does fix your problem, I'll close this.

Is this still a problem? We're now on 3.1.0 by the way.

if your node version is v0.12.xxxx , you can use
npm install node-webkit-builder -g
and build it.

nw-builder mast less than V4.0 +
