müssen Sie angular4 von angular2 in Visual Studio 2017 überprüfen

Question

Ich habe meine Quelle von Angularjs2 auf Angularjs4 aktualisiert.

Ich verwende Visual Studio 2017 und ASP.NET MVC Core.

Ich möchte jetzt entweder die aktualisierte Version (4) oder die vorherige Version (2) überprüfen.

hier ist mein package.json

{ 
    "name": "angular-quickstart", 
    "version": "1.0.0", 
    "description": "QuickStart package.json from the documentation, supplemented with testing support", 
    "scripts": { 
    "build": "tsc -p src/", 
    "build:watch": "tsc -p src/ -w", 
    "build:e2e": "tsc -p e2e/", 
    "serve": "lite-server -c=bs-config.json", 
    "serve:e2e": "lite-server -c=bs-config.e2e.json", 
    "prestart": "npm run build",

    "pretest:once": "npm run build", 
    "test:once": "karma start karma.conf.js --single-run", 
    "lint": "tslint ./src/**/*.ts -t verbose" 
    }, 
    "keywords": [], 
    "author": "", 
    "license": "MIT", 
    "dependencies": { 
    "@angular/common": "~4.0.0", 
    "@angular/compiler": "~4.0.0", 
    "@angular/core": "~4.0.0", 
    "@angular/forms": "~4.0.0",

    "@angular/platform-browser": "~4.0.0", 
    "@angular/platform-browser-dynamic": "~4.0.0", 
    "@angular/router": "~4.0.0", 

    "angular-in-memory-web-api": "~0.3.0", 
    "systemjs": "0.19.40", 
    "core-js": "^2.4.1", 
    "rxjs": "5.0.1", 
    "zone.js": "^0.8.4" 
    }, 
    "devDependencies": { 
    "concurrently": "^3.2.0", 
    "lite-server": "^2.2.2", 
    "typescript": "~2.1.0", 

    "canonical-path": "0.0.2", 
    "tslint": "^3.15.1", 
    "lodash": "^4.16.4", 
    "jasmine-core": "~2.4.1", 
    "karma": "^1.3.0", 
    "karma-chrome-launcher": "^2.0.0", 
    "karma-cli": "^1.0.1", 
    "karma-jasmine": "^1.0.2", 
    "karma-jasmine-html-reporter": "^0.2.2", 
    "protractor": "~4.0.14", 
    "rimraf": "^2.5.4", 

    "@types/node": "^6.0.46", 
    "@types/jasmine": "2.5.36" 
    }, 
    "repository": {} 
} 

und dann wiederhergestellt i Paket-Manager durch.

muss ich etwas in tsconfig.js und andere Datei (en) upgraden?

Answer 1

Folgen zu diesem Pfad zu Ihrem Projektordner:

node_modules -> @angular -> core -> package.json 

dann prüfen „_id“ auf der Datei, zum Beispiel:

"_id": "@angular/core@4.1.3" 

die Versionsnummer am Ende ist Ihre tatsächliche Winkelversion .
