Unexpected identifier 'enableVueLoader'

[bunkerskyi]

I start the Encore ./node_modules/.bin/encore dev and get this error:

/home/kribeetko/PhpstormProjects/ESUNZ/node_modules/@symfony/webpack-encore/index.js:378
enableVueLoader(vueLoaderOptionsCallback = () => {}) {
^^^^^^^^^^^^^^^

My webpack.config.js:

let Encore = require("@symfony/webpack-encore");

Encore
    .setOutputPath('web/build/')
    .setPublicPath('/build')
    .cleanupOutputBeforeBuild()
    .addEntry('scripts', './assets/app.js')
    .addStyleEntry('styles', './assets/app.scss')
    .enableVersioning()
    .enableSassLoader({
        resolve_url_loader: false
    })
    .enablePostCssLoader()
    .autoProvidejQuery()
    .autoProvideVariables({
        $: 'jquery',
        jQuery: 'jquery',
        'window.jQuery': 'jquery'
    })
    .configureBabel(function(babelConfig) {
        babelConfig.presets.push('es2017');
    })
    .enableSourceMaps(!Encore.isProduction());

module.exports = Encore.getWebpackConfig();

I encountered the issue, too. It's in the latest version of Encore (0.9.0). Symfony Demo uses 0.7.2 and it works without any issues.

that error log mentioned by npm:

Sorry about that! Fixed in 0.9.1 (run yarn upgrade) and we updated CI to catch this in the future :).

Cheers!
