I'm having trouble with my squish-jquery task. When it runs, it throws this error:

Starting 'squish-jquery'...

events.js:85

I've looked it up, but unfortunately, I can't find anything relevant to my error. Is it a problem with my setup or with Uglify? Here is my gulpfile.js:

• Which line is on line 85? – Gary Storey Commented Apr 30, 2015 at 20:09
• gulp.watch('src/js/ponents-controllers/*.js', ['build-ponents']); – Samuel Hill Commented Apr 30, 2015 at 20:12
• Sorry in events.js line 85. Looks like it's working but failing validation. – Gary Storey Commented Apr 30, 2015 at 20:14
• Events.js isn't something I set up. It looks like it's a file in node_modules/karma/lib/. Line 85 is blank. – Samuel Hill Commented Apr 30, 2015 at 20:17
• what happens if you turn off mangling of the variables? .pipe(plugins.uglify( { mangle : false )) or do an on('error') after the uglify call? – Gary Storey Commented Apr 30, 2015 at 20:25

1 Answer 1

Per my ment above, you should turn on error logging for the uglify plugin to determine where the error is acrually occurring:

//....
.pipe(uglify())
.on('error', function(){
  //do whatever here
})
//....
