TypeError: _end is not a function

[angusfretwell]

Hi, just started getting this after going from 3.1.0 to 3.1.1 (very confusing since I had it working locally then build failed on Heroku... that'll teach me for not shrinkwrapping). Tried on node v5.4.1 and v6.5.0.

/Users/angusfretwell/Sites/redacted/node_modules/gulp-useref/lib/end.js:14
            return _end();
                   ^

The part of my Gulpfile using this is (the .twig files are essentially HTML, was working fine previously):

gulp.task('html', ['styles', 'scripts'], () =>
  gulp.src('app/templates/**/*.twig')
    .pipe(useref({ searchPath: ['public'], base: 'public' }))
    .pipe(gulpif('*.js', uglify()))
    .pipe(gulpif('*.css', cssnano()))
    .pipe(gulp.dest('public/templates'))
);

Please let me know if you can't reproduce and I'll put something together.

Yep. I am aware of the issue. My apologies. The workaround for now is go back to 3.1.0 See below.

Fixed with version 3.1.2. Apologies for breaking things.

[angusfretwell]

@jonkemp Thanks for fixing this up so quickly! No worries about breaking things, easy workaround.

Thanks for this plugin by the way, I use it heaps!

Yeah, I've had these changes in the repo for a few months but not published to npm. I guess because the tests weren't passing! Well, I tested this on a VM before publishing today and everything was good. I didn't realize that it had Node version 4.x! So right after I published it, I happened to test against 5 and 6 on two other machines and saw that it was actually broken. I was able to quickly fix the issue, so hopefully it didn't affect too many people.

Glad it helps you! Thanks!
