Missing package.json during rebuild

[ef4]

Using ember fastboot --watch --serve-assets with beta.8, the first build of my app is OK, the second build always fails because dist/package.json is missing and the npm install fails.

This is also related to #246 and I was able to reproduce in beta.4 as well before --watch landed.

Hey, I'm running into this issue as well.

Here is my stack trace:

$ ember fastboot --serve-assets --watch

Installing FastBoot npm dependencies
There was an error trying to run your application in FastBoot.

This is usually caused by either your application code or an addon trying to access an API that isn't available in Node.js.
Based on the stack trace, it looks like the exception was generated in node_modules/fastboot/src/ember-app.js on line 245.
The exception is probably coming from your app. Look at this file and line number to determine what is triggering the exception.

The full stack trace is:

In case it's helpful, here's a repo that reproduces this issue on a fresh Ember-cli 2.7 app with ember-cli-fastboot@1.0.0-beta.8 installed. The issue does not appear to happen when beta.7 is installed. https://github.com/steveszc/reproduce-fastboot-serve-assets-issue

Seems like maybe the regression was introduced here: bfc9855

I am running into this issue as well. Here's my console output/stack trace:

Sorry this is taking so long to fix, we've got some improvements to the overall way the build works that should address this but it's taking longer than I anticipated. Thanks for your patience! I will close this issue in favor of #246.
