AOT: Compilation sometimes fails on serve

[seeruk]

OS?

Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)

Mac OSX 10.11.6 (El Capitan)

Versions.

Please run ng --version. If there's nothing outputted, please run in a Terminal: node --version and paste the result here:

$ ng --version
angular-cli: 1.0.0-beta.18
node: 6.9.1
os: darwin x64

Repro steps.

Was this an app that wasn't created using the CLI? What change did you do on your code? etc.

The app was created with the CLI tool. I created a completely fresh, brand-new project, ran $ ng serve --aot, and then made a (any) change to a file. At this point, the browser reloads, and sometimes the error shown below is given.

The log given by the failure.

Normally this include a stack trace and some more information.

Note, this doesn't happen every time. It seems like it's only sometimes, randomly. Perhaps a race condition?

Mention any other details that might be useful.

N/A currently.

I have the same problem since this morning.

I believe it is something to do with the codebase? If I create a fresh project, with ng new I don't get the error.

It doesn't happen every time, but it definitely happened on a completely new, fresh project. The only thing I changed was "app works!" to "app doesn't work!".

To add a tiny bit more information here, I'm using a 15" mid-2014 Retina MacBook Pro (base model). I was inside of a tmux session. I use iTerm2 v3, and fish shell.

Strange, now it is working for me without a problem.

Can confirm the same error happens when some file is changed, than goes away when I save a file a second/third time.

Uncaught Error: Module build failed: Error: ENOENT: no such file or directory, open '/home/foo/projects/bar/src/app/app.module.ngfactory.ts'

Very annoying bug.
