ecmascript 6 - Yeoman fail with gulp in babel (es2015) -

i created yeoman generator , when start using babel e.g. change gulpefile.js gulpfile.babel.js (and add .babelrc file) outside gulpfile.js (not project gulpfile.babel.js) start fail.

the project generated gulpfile.babel.js works. , manage pin point failed gulp task gulp pre-test.

i managed pinpoint failed gulp task gulp pre-test:

gulp.task('pre-test', function () {   return gulp.src('generators/**/*.js')     .pipe(excludegitignore())     .pipe(istanbul({       includeuntested: true     }))     .pipe(istanbul.hookrequire()); }); 

the error message:

[10:26:27] using gulpfile ~/webstormprojects/generator-jekyll-starter-kit/gulpfile.js [10:26:27] starting 'pre-test'... failed parse file: /users/nirgalon/webstormprojects/generator-jekyll-starter-kit/generators/app/templates/my-awesome-site/gulpfile.babel.js  events.js:160       throw er; // unhandled 'error' event       ^ error: unable parse /users/nirgalon/webstormprojects/generator-jekyll-starter-kit/generators/app/templates/my-awesome-site/gulpfile.babel.js  line 3: unexpected token 

the gulpfile.babel.js around line 3:

'use strict';  import gulp 'gulp'; import gulploadplugins 'gulp-load-plugins'; import runsequence 'run-sequence'; import browsersync 'browser-sync';  const $ = gulploadplugins();  // minify html. gulp.task('minify-html', () => {   return gulp.src('_site/**/*.html')     .pipe($.htmlmin({       removecomments: true,       collapsewhitespace: true,       collapsebooleanattributes: true,       removeattributequotes: true,       removeredundantattributes: true,       removeemptyattributes: true,       removescripttypeattributes: true,       removestylelinktypeattributes: true,       removeoptionaltags: true     }))     .pipe(gulp.dest('_site')) }); 

i try figure out, no success (i thought has babel, , tried install babel in project root package.json).

you're using es2015 in gulpfile. chance node version doesn't support it?
