gulp-browserify error during compilation of jade i

问题:

Sorry for possible mistakes in the writing - use the Google translator.
I use the gulp-browserify

gulpfile.js -

gulp.task('jade', function(){
    gulp.src('app/src/*.jade')
    .pipe(plumber(/*{ErrorHandler: notify.onError("<% error.massage %>")}*/))
    .pipe(browserify({
        transform: ['jadeify'],
        extension: ['.jade']
    }))
    .pipe(rename('*.html'))
    .pipe(gulp.dest('app/dev'))
})

error -

[14:20:53] Plumber found unhandled error: SyntaxError in plugin 'gulp-browserify' /home/acopalipsis/proj/app/src/fake_723954d4.js:1
doctype html
^ ParseError: Unexpected identifie

index.jade -

doctype html
html(lang="en")
head
    meta(charset="UTF-8")
        title Test
body

Why the error? How to fix?

***********************************ADDED***********************************
Made -

gulp.task('jade', function(){
    browserify(['./app/src/index.jade'])
    .transform(jadeify)
    .bundle({debug:false})
    .pipe(source('index.html'))
    .pipe(gulp.dest('app/dev'))
})

But the generated html consists of 224 js code... Why?
If you want to display this code, tell me, I'll show!
***********************************ADDED-PART-TWO***********************************
index.html after the task execution -
And if I understand Your words, that this code is designed to display index.jade in the browser? But in the browser when opening index.html displays only the code is written below.

Looks like this is an issue with gulp-browserify and jadeify.

You can wait until those are resolved upstream, or just use browserify directly:

// ... require other gulp related modules
var browserify = require('browserify');
// allow browserify to play nicely with gulp's streams
// more info: https://www.npmjs.org/package/vinyl-source-stream
var source = require('vinyl-source-stream');

gulp.task('jade', function() {
  // unfortunately, you do miss out on
  // globbing with this method
  browserify(['./app/src/index.jade'])
  .transform(require('jadeify'))
  .bundle()
  .pipe(source('index.html'))
  .pipe(gulp.dest('app/dev'));
});

Another note note, you have an error in index.jade:

head
    meta(charset="UTF-8")
        title Test

Should be:

head
    meta(charset="UTF-8")
    title Test

(meta should not have any child elements.)
