Describe the bug
After following this guide to upgrade to NativeScript 8.2.0 from 8.1.5, now when I run "npm install" it gives these warnings:

MacBook-Pro:UI justintoth$ npm install
npm WARN EBADENGINE Unsupported engine {
npm WARN EBADENGINE   package: '@eslint/eslintrc@1.2.1',
npm WARN EBADENGINE   required: { node: '^12.22.0 || ^14.17.0 || >=16.0.0' },
npm WARN EBADENGINE   current: { node: 'v14.16.0', npm: '8.3.1' }
npm WARN EBADENGINE }

npm WARN EBADENGINE   current: { node: 'v14.16.0', npm: '8.3.1' }
npm WARN EBADENGINE }
npm WARN EBADENGINE ...

Worse, when trying to build it throws errors about "fs":

Here is the full build log: https://gist.github.com/justintoth/d8fde7b79e45df5f2f3310cf56d04edd

まず、報告されている NativeScript、Angular、Node、npm のバージョンで npm install と NativeScript のビルドを再現します。src/app/shared/services/analytics.service.ts から @nativescript/firebase-crashlytics までのインポートチェーンを追跡し、リンクされた完全なビルドログを調べて依存関係の失敗を確認します。報告されたプロジェクトが、表示されたモジュール解決エラーなしでインストールおよびビルドできれば完了です。
