Problem on first server start

[fredcy]

When I install and run this application from scratch on OS X I always get an error when I first run mix phoenix.server and browse the page:

[info] Running ElmBlogger.Endpoint with Cowboy using http on port 4000

        if (error) throw new Error(formatError('Reading', error));
                   ^

  at FSReqWrap.readFileAfterOpen [as oncomplete] (fs.js:324:13)

When I then interrupt (abort) the phoenix server and start again, no errors appear and the page works as expected.

So something goes wrong the first time through. I think I've seen the same thing recur if I delete elm-stuff completely.

I defer to @knewter

I think this relates to everything within web/static being watched, including web/static/elm/elm-stuff.

Adding "elm-stuff" as an exclusion in conventions.ignored does not suffice.

I can confirm this issue. Works fine after Phoenix server restart.

I have something similar, but here LICENSE couldn't be found.

And also simply restarting the server seems to work.
