Fresh clone + install + ember serve fails.

[cibernox]

I'm getting a pretty bad error by just cloning the repo and running ember s on it.

$ ember s

I've seen this failure fairly regularly recently on latest Macs with the new APFS file system. It's also been causing Watchman to freeze up, and the only fix I've found is brew uninstall watchman && brew install watchman. Unsure this is related specifically to this addon

[cibernox]

The weirdest part is that I don't have watchman and it doesn't happen to me in other repos

[pzuraq]

Yeah, I started by uninstalling watchman when it started freezing up, and then I started getting these errors from Node FileWatcher so I had to reinstall watchman 😕

[ro0gr]

The same issue on win10. So it doesn't seem like a watchman related thing...

[dfreeman]

@ro0gr You're seeing all that FSEvents.framework stuff on Windows? I'm pretty sure that's specifically a macOS API, and node uses something else entirely on Windows.

[dfreeman]

@cibernox FWIW, I've run into that error when doing non-Watchman file watching in other projects since switching to APFS, which seems to have reset (and lowered the hard cap on) the limit for open file descriptors. What do you get for ulimit -n?

[cibernox]

ulimit -n => 4864
I checked and it works with watchman, but fails without it

[Dhaulagiri]

I saw the same issue trying to use this addon in another addon. I was only able to get it working by installing watchman.

[ro0gr]

@dfreeman you are right. I have a different error. However in my opinion these issues are pretty similar. Build errors recurrently repeat somewhere in tmp/ and it's difficult to stop.

Here is my npm start output:

Maybe we should detect such cases and stop the server? or it should be handled by ember-cli...
