Are you using vagrant?

Here is our full scss build file:

#!/usr/bin/env node

var fs = require('fs');
var sane = require('sane');
var sass = require('node-sass');

var watcher = new sane.Watcher('./components', {glob: ['*/.scss'], poll: true});

var buildSass = function () {
sass.render({
file: './components/app.scss',
sourceMap: true,
success: function (css) {
fs.writeFile('./public/public_assets/css/built.css', css, function (error) {
if (error) return console.log(error);
console.log('CSS built');
});
},
error: function (error) {
console.log(error);
}
});
};

if (!fs.existsSync('./public/public_assets/css')) {
fs.mkdirSync('./public/public_assets/css/');
}

watcher.on('ready', function () {
console.log('SCSS being watched');
buildSass();
});
watcher.on('change', function (filepath) {
console.log('file changed', filepath);
buildSass();
});
watcher.on('add', function (filepath) {
console.log('file added', filepath);
buildSass();
});
watcher.on('delete', function (filepath) {
console.log('file deleted', filepath);
buildSass();
});

This line seems to be the issue:

var watcher = new sane.Watcher('./components', {glob: ['*/.scss'], poll: true});

If poll: true is removed or set to false the build task does not run when
a file is saved even though the watcher.on('ready') is being fired. When poll:
true is set though it builds on save like it should.

We are not.

[amasad]

What OS and version are you on? are you using any VMs?

[dadambickford]

OS X Yosemite 10.10
Sane version 0.8.0, 0.8.1

Strangest damn thing is that a fresh setup of our repo on my partners machine does not yield the same problem.

Can you try restarting your computer?
If that didn't work, go to OS X Activity Monitor, search for fseventd and stop it (it will restart itself instantly) and then try again? Let me know if that works

[dadambickford]

Not working after both of those suggestions. I did see 3 other processes named 'dbfseventsd' though?

[amasad]

does any other non-polling watching library work for you?

[dadambickford]

We tried https://github.com/mikeal/watch but I think that polls as well, just super slowly. Any suggestions of one to try?

[amasad]

try https://github.com/paulmillr/chokidar But make sure it's not in poll mode

[dadambickford]

That actually did work with usePolling set to false. Any ideas?

[amasad]

What version of node are you running?

Ok I'm not sure what affect this would have, but I had this weird loading bar start showing up on login (which appears I'm not the only one) and in looking for a solution to that one post suggested resetting the PRAM (holding cmd + opt + P + R on startup), and Sane appears to be working as normal again with the polling set to false. I'm not positive it's related, but either way it seems we can close this.
