試した手順： 問題にプロポーザル数値セパレータモジュールがないと思ったので、以下のコマンドでモジュールをインストールしました

    npm i @babel/plugin-proposal-numeric-separator

それでも問題は解決しなかったため、同様の問題で示された回答を試しても、同じエラーが発生しました。

この問題を修正する方法は？

issue8680のnicolo-ribaudoに感謝

依存関係の追加@ babel / compat-data "：" 7.8.0 "で問題が解決しました。

vi package.json

    "dependencies": {
        "@babel/compat-data": "7.8.0",
        ...
    }

npm install

ng build --prod

わたしにはできる

ステップ1：devDependenciesに追加： " @ babel / compat-data"： "7.8.0 "

ステップ2：実行-npmインストール
