native-notifier crashes on Ubuntu

Description

So, Brunch doesn’t (on Ubuntu 16.04) pick up filesystem changes directly. That’s fixable with watchers: {usePolling: true}.

What isn’t fixable is that if a *.scss file throws an error during compilation, it crashes brunch in watch mode.

Expected behavior

When I run node node_modules/brunch/bin/brunch w -d and I have a source file with an error in it, Brunch should log the error but not crash.

Actual behavior

It crashes:

  brunch:watch change <snip> +9m
  brunch:list Reading <snip> +1ms

Any idea why that works?

I updated my comment so you are probably seeing the original comment.

As you can see the crash is with the notify-send service/package.

Error: spawn notify-send ENOENT
  at exports._errnoException (util.js:1018:11)
  at Process.ChildProcess._handle.onexit (internal/child_process.js:193:32)

  at _combinedTickCallback (internal/process/next_tick.js:80:11)
  at process._tickCallback (internal/process/next_tick.js:104:9)

I meant to file an issue and got slammed last week.

Hey guys, thanks for the report.

I believe notify-send is missing on your systems, right?
