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

[maiermic]

I switched from 6to5ify@3.1.2 to babelify@6.1.3 and at the same time upgraded browserify from 6.3.4 to 10.2.6, watchify from 2.3.0 to 3.2.3 and remapify from 1.4.3 to 2.0.3. Now I get several build errors: 'import' and 'export' may appear only with 'sourceType: module'

My build file looks more or less like this:

const browserify = require('browserify');
const babelify = require('babelify');
const remapify = require('remapify');
const watchify = require('watchify');

const b = browserify({
  cache: {},
  packageCache: {},
  fullPaths: false,
  debug: true
});
b.add(myFile);
b.transform(babelify);
b.plugin(remapify, [...]);
watchify(b).bundle(function(err, buf) { ... });

This error does not appear with pathmodify instead of remapify (see).

I've got somewhat similar with jadeify@^4.4.0 + remapify@^2.1.0 (using in grunt-browserify@~4.0.1 setup).
grunt-browserify config:

options: {
    plugin: [
        [
            'remapify',
            [{
                src: '**/*.*',  // glob for the files to remap
                expose: '',
                cwd: path.join(__dirname, 'media', 'source', 'scripts')
            }]
        ]
    ],

    transform: [
        ['jadeify', {
            compileDebug: debug,
            pretty: false
        }]
    ]
},

When I try to require .jade files using the mapped alias (e.g. lib/templates/template.jade) I'm getting an error:

>> __dir-name__/template.jade:1
>> .help
>> ^
>> ParseError: Unexpected token

However, without the mapping it works well - if I just specify the full relative path ('../../../../lib/templates/template.jade')

Switching to pathmodify seems to solve the issue, btw.
