yo ng-poly commands all crash when choosing a module

[d-rep]

When I'm using ng-poly to create anything (angular service, view, etc) inside an existing ng-poly project, it asks me to choose a module but doesn't display a list of the modules in my project. When I hit the up or down arrow keys, it crashes.

yo ng-poly:service a
? Which module is this for? (Use arrow keys)
? Which module is this for?

This is generator-ng-poly@0.11.3 and Node v5.0.0 and npm v3.3.9 on a Mac. I've also tried downgrading to ng-poly 0.11.2 and 0.11.1 and got the same behavior.

Weird. Does using yo ng-poly:service a --module=home work? I'll try to look into this tonight.

[d-rep]

Yes - that's a good workaround, thanks Dustin.

$ yo ng-poly:service a --module=home

I haven't been able to reproduce this on my Mac. Is your project public by any chance? Or even a file structure with changed names?

Not sure why the module choice selector doesn't work, while the module flag does work.

After selecting the module generating a directive, I get the error below. I alsoget the same error if I type the module manually: yo ng-poly:directive someDirective --module=base/someModule

My project uses typescript. Ubuntu 14.04 LTS npm version: 2.14.12 ng-poly version: 1.5.1 Thanks in advance.

I believe this has been fixed, if not please feel free to re-open.
