[kking124]

What were you expecting to happen?

gulp to run (specifically, compile some handlebars templates)

What actually happened?

gulp crashed

> gulp templates

Please post a sample of your gulpfile (preferably reduced to just the bit that's not working)

var gulp = require('gulp');
var templates = require('./gulp/templates');
gulp.task('templates', templates);

var gulp = require('gulp');
var path = require('path');
var handlebars = require('gulp-handlebars');
var wrap = require('gulp-wrap');
var declare = require('gulp-declare');
var concat = require('gulp-concat');
var merge = require('merge-stream');

module.exports = function() {

    //process partials
    var partials = gulp.src('./templates/partials/**/*.hbs')

        .pipe(handlebars())

        .pipe(wrap('Handlebars.registerPartial(<%=  processPartialName(file.relative) %>, Handlebars.template(<%= contents %>) );',{},{
            imports:{
                "processPartialName": function(fileName) {

                    return JSON.stringify(path.basename(fileName, '.js'));

                }
            }
        }));

    var templates = gulp.src(['./templates/**/*.hbs', '!./templates/partials/**/*.hbs'])

        .pipe(handlebars())

        .pipe(wrap('Handlebars.template(<%= contents %>)'))

        .pipe(declare({

            namespace: 'app.templates',

            noRedeclare: true

        }));

    return merge(partials, templates)

        .pipe(concat('combined.js'))

        .pipe(gulp.dest('./public/assets/templates/'))

}

OS: Windows 10 April 2018 Update

I suspect this is related to issue #2162 but the included fix did not work. The problem began to occur after upgrade to April 2018
