So I am using the Aurelia skeleton-navigation starter as recommended. However, when I run the gulp bundle task the application will no longer load the main UI, it get's stuck on the spinner/loading page. I found this issue but even after installing the jspm beta it still doesn't seem to be resolved. Anyone had any luck? For what it is worth, I do not even see an aurelia.js bundle being created in the /dist directory so the 404 certainly makes sense in that respect.
So I have a fix, I am not thrilled with it though. It seems if you run bundle then run gulp watch to start the webserver, that the bundled files get wiped out from the dist folder. Running gulp watch in one command window and gulp bundle in another results in it working correctly as the bundled js is there at that point. I hope for a better fix from someone, this seems kind of hacky.
