"SyntaxError: 'import' and 'export' may appear only with 'sourceType: module'"

Not sure what’s going on, but this message just started showing up…

“SyntaxError: ‘import’ and ‘export’ may appear only with ‘sourceType: module’”

Here’s the relevant bit from my gulp file:

'use strict';

var gulp = require('gulp'),
    notify = require("gulp-notify"),
    babelify = require('babelify'),
    browserify = require('browserify'),
    browserSync = require('browser-sync'),
    source = require('vinyl-source-stream'),
    uglify = require('gulp-uglify'),
    buffer = require('vinyl-buffer');

var vendors = [
  'jquery',
  'moment',
  'd3',
  'queue-async',
  'react',
  'react-dom',
  'react-bootstrap',
  'react-infinite',
  'lodash',
  'rc-switch',
  'rc-slider',
  'he',
  'react-debounce-input',
  'react-swipe-views',
  'react-modal',
];


gulp.task('app', function () {
    var stream = browserify({
            entries: ['./app/app.jsx'],
            transform: [babelify],
            debug: false,
            extensions: ['.jsx'],
            fullPaths: false
        });

    vendors.forEach(function(vendor) {
        stream.external(vendor);
    });

    return stream.bundle()
                 .pipe(source('build.min.js'))
                 .pipe(buffer())
                 .pipe(uglify())
                 .pipe(gulp.dest('build/js'))
                 .pipe(notify("Successfully built build.min.js file!"));

});

I’m not sure what happened, but things were fine just a few days ago. Thanks!

You upgraded to babelify 7.0, which uses the new babel 6.0, and you’re missing options. Please checkout the README.

I’m sorry you feel that way. I offered to personally debug your issue if you provided me with some code. I didn’t meant to offend. Please remember that we’re all volunteers here and just trying to make cool things.
