Angular 4. Exportation de jeton inattendue

Ensuite, je lance l'application avec la commande ng serve dans la console. Je vois une erreur:

VM1018:2297 Uncaught SyntaxError: Unexpected token export
            at eval (<anonymous>)
            at webpackJsonp.../../../../script-loader/addScript.js.module.exports (addScript.js:9)
            at Object.../../../../script-loader/index.js!../../../../popper.js/dist/popper.js (popper.js?6efa:1)

Il suffit ensuite de démarrer l'application angulaire, d'installer: bootstrap, jQuery, popper.js puis d'ajouter des fichiers de styles et de scripts à angular-cli.json Angular-cli.json:

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "project": {
    "name": "Web"
  },
  "apps": [
    {
      "root": "src",
      "outDir": "build",
      "assets": [
        "assets",
        "favicon.ico"
      ],
      "index": "index.html",
      "main": "main.ts",
      "polyfills": "polyfills.ts",

        "../node_modules/popper.js/dist/popper.js",

      ],
      "environmentSource": "environments/environment.ts",
      "environments": {
        "dev": "environments/environment.ts",
        "prod": "environments/environment.prod.ts"
      }
    }
  ],
  "e2e": {
    "protractor": {
      "config": "./protractor.conf.js"
    }
  },
  "lint": [
    {
      "project": "src/tsconfig.app.json",
      "exclude": "**/node_modules/**"
    },
    {
      "project": "src/tsconfig.spec.json",
      "exclude": "**/node_modules/**"
    },
    {
      "project": "e2e/tsconfig.e2e.json",
      "exclude": "**/node_modules/**"
    }
  ],
  "test": {
    "karma": {
      "config": "./karma.conf.js"
    }
  },
  "defaults": {
    "styleExt": "css",
    "component": {}
  }
}

je suis utiliser:

node 8.4.0
npm 5.3.0
jquery 3.2.1
bootstrap 4 beta

Où est-ce que je fais une erreur? Du texte ou autre chose pour poster cette quête avec une grande partie du code (mon anglais est très mauvais, je sais ...)

J'ai trouvé la réponse. Dans ./.angular-cli.json à la ligne scripts changer le dossier de: "../node_modules/popper.js/dist/popper.js"

à cela (si vous utilisez la version moderne de webpack):

"../node_modules/popper.js/dist/esm/popper.js"

sinon ceci:

"../node_modules/popper.js/dist/umd/popper.js"

Merci fezVrasta

c'est parfait pour travailler sur angular4/6, je l'ai testé dans mes projets. 

"../node_modules/popper.js/dist/umd/popper.js"
