Das Plugin "Proposal-Numeric-Separator" in der Winkel-App konnte nicht gefunden werden

Ich erhalte unter Fehler beim Laufen ng build --prod.

An unhandled exception occurred: [BABEL] /root/catch-up-enterprise/dist/polyfills-es5.8e4ba13e1c10f0a37bb4.js: Could not find plugin "proposal-numeric-separator".

Schritte versucht: Ich dachte, das Problem fehlt Vorschlag-numerisch-Trennmodul, also installierte das Modul über den folgenden Befehl

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

Das Problem wurde immer noch nicht behoben. Versuchen Sie es mit der Antwort in dem ähnlichen Problem. Es ist immer noch der gleiche Fehler aufgetreten.

Wie kann ich dieses Problem beheben?

Danke an nicolo-ribaudo von issue8680

Das Hinzufügen der Abhängigkeit @ babel / compatible-data ":" 7.8.0 "hat das Problem für mich behoben.

vi package.json

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

npm install

ng build --prod

Für mich geht das

Schritt 1: Fügen Sie in Ihren devDependencies Folgendes hinzu: " @ babel / compatible-data": "7.8.0 "

Schritt 2: run - npm install
