Hyperloop compilation error

Question

I've written before about a problem running Hyperloop project. If run a newly created project to witch I added Hyperloop from Appcelerator Studio it seems like compilation is stuck on:

[INFO]  Starting Hyperloop assembly
[INFO]  Skipping Hyperloop compile, no usage found ...

So what I did now is to run it from command line using:

HyperloopApp ophir$ appc run -p ios

And right after Skipping Hyperloop compile, no usage found ... I get the following error messages:

/Users/ophir/Documents/Appcelerator_Studio_Workspace/HyperloopApp/plugins/hyperloop/hooks/ios/hyperloop.js:581
        return callback();
         ^
ReferenceError: callback is not defined

How can I make Hyperloop run?

Answer 1

I found the solution. apparently it seems to be a permission problem - even if the message isn't so. since I had the following line:

[INFO]  Skipping Hyperloop compile, no usage found ...

I decided to add a minimal Hyperloop code inside the project:

var UIView = require('UIKit/UIView');

Then when I ran again I got a different error message starting with:

Error: spawn EACCES

This is something I already know to be permission issues - and it makes sense since the Hyperloop module was downloaded from the internet.

fixup was easy, just run

sudo chmod -R a+rwx /appfolder

everything compiles.
