Gulp keeps crashing?

Question

Node.js

Gulp constantly crashes, although it starts up, it worked clearly. The server starts, no errors, but there is no connection to the server. Accordingly, there is no compilation. The browser cannot access the site ( locallhost.com/.)
The localhost site does not allow a connection to be established.
Perhaps you meant locallhost.com/.
Search Google for localhost

global.hostname = "localhost";
var gulp = require('gulp'),
sass = require('gulp-sass'),
autoprefixer = require('gulp-autoprefixer'),
minifycss = require('gulp-minify-css'),
rename = require(' gulp-rename');
gulp.task('express', function() {
var express = require('express');
var app = express();
app.use(require('connect-livereload')({port: 35729}));
app.use(express.static(__dirname + '/app'));
app.listen('80', hostname);
});
var tinylr;
gulp.task('livereload', function() {
tinylr = require('tiny-lr')();
tinylr.listen(35729);
});
var fileName = require('path').relative(__dirname, event.path);
tinylr.changed({
body: {
files: [fileName]
}
});
}
gulp.task('styles', function () {
gulp.src('sass/*.sass')
.pipe(sass({
includePaths: require('node-bourbon').includePaths
}).on('error ', sass.logError))
.pipe(rename({suffix: '.min', prefix : '_'}))
.pipe(autoprefixer({
browsers: ['last 15 versions'],
cascade: false
}))
.pipe(minifycss())
.pipe(gulp.dest('app'));
});
gulp.task('watch', function() {
gulp.watch('sass/*.sass',
gulp.watch('app/*.css', notifyLiveReload);
gulp.watch('app/*.html', notifyLiveReload);
});
gulp.task('default', ['styles', 'express', 'livereload', 'watch'], function() {
});
