Windows - unhandled error on editing js file

[seamc]

Whenever I edit and save a Javascript file under ~/prj/src/scripts, I receive the error listed below. No further information is provided within the gulp script or the error.

The output below is the same between cygwin and windows command prompt. The error below has occurred on Win7 and Win8 with fresh installs of node.js v0.10.28

$ gulp

Have you checked permissions of main.js? User that runs gulp should be able to read/write main.js.

OK, my bad. Seems like it doesn't work on Windows properly. I'll look into it.

I have not been able to fully debug the problem, but I ran pho through node-inspector and found that the stack dies after gulp's vinyl-fs's mkdirp attempts a write to \dist\scripts\main.js

mkdirp's call stack is as follows:

            // In the case of any other error, just see if there's a dir
            // there already.  If so, then hooray!  If not, then something
            // is borked.
            default:
                fs.stat(p, function (er2, stat) {
                    // if the stat fails, then that's super weird.
                    // let the original error be the failure reason.
                    if (er2 || !stat.isDirectory()) cb(er, made)
                    else cb(null, made); //  <----- pho callback here
                });
                break;

I will try to investigate more; pho seems like a very cool tool, but I am not the fastest with node debugging.
