when js has syntax error， this plugin output nothing but error stack.

events.js:72
        throw er; // Unhandled 'error' event
              ^

What version of gulp-uglify and what version of gulp? We've been providing what file failed as part of the error for a while now.

gulp 3.8.7
gulp-uglify 0.3.1

rhys-vdw · 2014-08-20T02:15:55Z

Should note that I'm not convinced that a syntax error is causing this error. I'm only using popular libraries and coffeescript output for my source files.

I might try narrowing down the problem... Is there any way to get some more debug info from the module?

terinjokes · 2014-08-20T11:43:40Z

gulp-uglify provides detailed information on the error message, via the "fileName", and "lineNumber" properties.

Please attach an error handler to the stream.

rhys-vdw · 2014-08-21T04:20:45Z

Okay, definitely my fault, I was accidentally streaming a css file into uglify. 😊

terinjokes · 2014-08-26T22:31:11Z

Providing a better documentation on gulp error management is being tracked in gulpjs/gulp#359.

devdattaT · 2014-10-27T11:35:25Z

For others like me, who do not know how to get the error message, here is what you need to do:

Install Gulp-util
import the Gulp-util by using the following statement: var gutil = require('gulp-util');
Finally, when you are uglifying the code, attach the error handler like this: .pipe(uglify().on('error', gutil.log))

plaimanus · 2014-11-27T04:48:44Z

I had the same problem too, Thank to @devdattaTpoined out how to show an error while compiling gulp uglify. I found out that one of mine .js files has an typo or it spits out an error. Thank you so much

check your .js files

jpaulobneto · 2014-12-28T00:58:29Z

@devdattaT Thanks for share this gulp-util log

ai · 2015-02-09T07:19:40Z

Why not add this info to README.md?

ghost · 2015-02-18T17:19:58Z

Thanks, solved my issue as well.

AliMD · 2015-03-12T09:36:19Z

please update your read me

terinjokes · 2015-03-18T21:07:38Z

@AliMD The README on the 1.2.0 branch contains some documentation on errors.

hello!

I use elixir + gulp, and i get the same error, someone can help me?
the function uglify() show ReferenceError: uglify is not defined

var elixir = require('laravel-elixir');
var gutil = require('gulp-util');

elixir(function (mix) {

    mix.browserify('Vue/main.js');

    mix.styles([

});

terinjokes · 2016-04-27T14:01:49Z

@mprandot Please see the README for how the use the recommended pump module instead of using those pipe functions directly. Then you'll get the better error messages this module already has.

mprandot · 2016-04-27T14:43:13Z

@terinjokes sorry!

I found the error, sintax error in one .js in mix.scripts

Thanks!

mrbacay · 2016-05-27T03:11:41Z

I'm having the same problem, and I've tried what @devdattaT suggested, but it's still giving me the same information. It stops at the error on events.js.

Do I have to pass the error event to gutil.log?

whoan · 2016-07-02T20:09:45Z

The fastest solution I've found was to capture the error with this:

process.on('uncaughtException', function(error) {
    console.log(error);
    process.exit(1)
})

I put that snippet in my gulpfile.js and I could figure it out where was the problem. It was a problem in my code.

terinjokes · 2016-07-02T20:37:37Z

If you use pump like the examples in the readme, errors will be
propagated to Gulp, which will format the errors correctly.
