javascript - No se puede actualizar la versión de Angular

Estoy intentando actualizar mi aplicación Angular. La versión de mi aplicación Angular es 4.2.4 para Aplicaciones Básicas. Estoy utilizando los pasos indicados en la Guía de Actualización de Angular.

Según la guía, tengo que ejecutar lo siguiente

npm install -g @angular/cli
npm install @angular/cli
ng update @angular/cli

Pero cuando intenté ejecutar el comando

ng update @angular/cli

me da un error que dice

Error: Cannot update safely because packages have conflicting dependencies. Package @angular/core would need to match both versions "7.2.15" and "8.2.7, which are not compatible.

Respuesta #1

Creo que puedes seguir este tutorial

O actualiza tu paquete de Angular manualmente a una versión algo así

"@angular/core": "~8.2.4"

Actualiza tu tsconfig.json así

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "module": "esnext", // add this line
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "importHelpers": true,
    "target": "es2015",// add this line
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2018",
      "dom"
    ]
  }
}

Actualizar :

Instalar rxjs-compact resuelve el problema
