Le nom du travail "..getProjectMetadata" n'existe pas

J'ai mis à jour mon angular vers la v9 et lorsque j'essaye de revenir dans la v8, je reçois cette erreur. J'ai déjà essayé ce qui suit:

  • désinstaller -global angular/cli
  • désinstaller angular/cli
  • revenir à mon dernier package.json
  • supprimer le dossier node_module
  • supprimer le dépôt

Cette erreur continue de s'afficher.

Mon stacktrace est:

An unhandled exception occurred: Job name "..getProjectMetadata" does not exist.
See angular-errors.log for further details.

angular-errors.log:

D'après mon expérience, un nouveau module que vous utilisez est conçu pour angular9 et vous devriez mettre à niveau vos importations si possible pour:

 "dependencies": {
    "@angular/animations": "^9.1.9",
    "@angular/cdk": "^9.2.4",
    "@angular/common": "^9.1.9",
    "@angular/compiler": "^9.1.9",
    "@angular/core": "^9.1.9",
    "@angular/forms": "^9.1.9",
    "@angular/platform-browser": "^9.1.9",
    "@angular/platform-browser-dynamic": "^9.1.9",
    "@angular/router": "^9.1.9",
 ...
}
"devDependencies": {
    "@angular-devkit/build-angular": "^0.901.7",
    "@angular/cli": "^9.1.7",
    "@angular/compiler-cli": "^9.1.9",
    "@angular/language-service": "^9.1.9",
   ...
}
