Mix v4.xにアップグレードした後でnpm run
を呼び出すと、mixが未定義になります。実行ごとに次のようなエラーが表示されます。

私はこれをLaravel 5.5で実行しています。package.json
をアップグレードして、laravel repoのバージョンがMix v4で使用されるようになりました。
これが私のpackage.json
です。

私のwebpack.mix.js
:
const { mix } = require('laravel-mix');
mix.js('resources/assets/js/app.js', 'public/js')
.sass('resources/assets/sass/app.scss', 'public/css')
.version()
.sourceMaps();
node_modules
とyarn install
をもう一度削除してみましたが、問題は解決しません。
V3にダウングレードした場合、一部のSASSのコンパイル以外の問題はありません。
webpack.mix.js
ファイルを確認しないと、問題の原因を特定するのは困難です。 Laravel= 5.5ブランチを複製して、^4.0.13
のバージョンlaravel-mix
にアップグレードし、yarn dev
とyarn prod
の両方を正常に実行しましたが、 npmとノードの最新バージョン。
これが GitHub repo のデモです。
更新
// TypeError: Cannot read property 'js' of undefined
const { mix } = require('laravel-mix');
// works
const mix = require('laravel-mix');
