rails webpacker angular - polyfills.ts - Ошибка: не удается разрешить 'core-js / es6 / refle'

Question

Кто-нибудь знает, как заставить последнюю версию Angular работать с Rails 5 Webpacker?

Я пробовал совершенно новую установку Angular 7.2 в Rails 5

bundle exec rails webpacker:install:angular

Answer 1

У меня есть обходной путь, выполнив следующее.

Измените core-js с ^ 3.0.0 на ^ 2.5.7 в

package.json

Затем выполните в корневой папке rails

установка пряжи

{
    "name": "klue-go",
    "private": true,
    "dependencies": {
        "@angular/common": "^7.2.10",
        "@angular/compiler": "^7.2.10",
        "@angular/core": "^7.2.10",
        "@angular/platform-browser": "^7.2.10",
        "@angular/platform-browser-dynamic": "^7.2.10",
        "@rails/webpacker": "3.5",

        "core-js": "^3.0.0",

        "core-js": "^2.5.7",


        "rxjs": "^6.4.0",
        "ts-loader": "3.5.0",
        "typescript": "^3.3.4000",
        "vue": "^2.6.10",

    },
