events.js:160 throw er; // Unhandled 'error' event
Solution 1
removing the node_modules folder, clearing npm cached files, and doing a fresh install, resolves this issue.
rm -rf node_modules && npm cache clean --force && npm install

Solution 2
Regarding the error at the following line:
events.js:160
throw er; // Unhandled 'error' event
The issue for me was that I already had the port open on another local node app.
Stopping the other app resolved the issue.

I was facing similar error while running my create-react-app on Ubuntu, while running a command npm start
It gets solved when I run sudo npm start
I think a problem might be with application not having enough permissions.
Solution 4
Try to kill other gulp processes.
ps -ax | grep gulp
kill -9 <number>
Solution 5
Lately, I changed the node version to v5.10.0 and everything just acted well.

The project I worked on was built with gulp.
Recently I updated the node version to v6.3.1. Then something came wrong.
A task named 'html' throws an error. Here is the part of error code of it.
bogon:toClient work$ gulp html (node:2519) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version. [10:26:10] Using gulpfile ~/Project/TIME_Cancer_Treatment_Centers_of_America(CTCA)/toClient/gulpfile.js [10:26:10] Starting 'html'... (node:2519) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version. events.js:160 throw er; // Unhandled 'error' event ^ Error: CSS parse error scripts/vendor.js: Unexpected input 1 |!function(t,e){"object"==typeof module&&"object"==typeof module.exports?module.exports=t.document?e(t,!0):function(t){if(!t.document)throw new Error("jQuery requires a window with a document");return e(t)}:e(t)}("undefined"!=typeof window?window:this,function(t,e){function i(t){var e="length"in t&&t.length,i=J.type(t);return"function"!==i&&!J.isWindow(t)&&(!(1!==t.nodeType||!e)||("array"===i||0===e||
And the code of task 'html':
var $ = require('gulp-load-plugins')(); gulp.task('html', function() { var assets = $.useref.assets({searchPath: ['.tmp']}); return gulp.src('app/*.html') .pipe(assets) .pipe($.if('*.js', $.uglify())) .pipe($.if('*.css', $.csso())) .pipe(assets.restore()) .pipe($.useref()) .pipe($.if('*.html', $.minifyHtml({conditionals: true, loose: true}))) .pipe(gulp.dest('dist')); });
I googled a lot but I haven't found a proper answer suitable for me.
