从4版升级到5版

Question

我有一个用角4写的应用程序。

package.json:

{
  "name": "frontend",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "build-bundle-report": "ng build --prod --stats-json && webpack-bundle-analyzer dist/stats.json",
    "bundle-report": "webpack-bundle-analyzer dist/stats.json"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "^4.1.3",
    "@angular/common": "^4.0.0",
    "@angular/compiler": "^4.0.0",
    "@angular/core": "^4.0.0",
    "@angular/forms": "^4.0.0",
    "@angular/http": "^4.0.0",
    "@angular/platform-browser": "^4.0.0",
    "@angular/platform-browser-dynamic": "^4.0.0",
    "@angular/router": "^4.0.0",
    "@ngui/datetime-picker": "^0.16.2",
    "angular2-modal": "^3.0.1",
    "angular2-text-mask": "^8.0.1",
    "core-js": "^2.4.1",
    "flexboxgrid": "^6.3.1",
    "moment": "^2.18.1",
    "ng-select": "^1.0.0-beta.5",
    "ng2-pagination": "^2.0.2",
    "ng2-toastr": "^4.1.0",
    "rxjs": "^5.1.0",
    "zone.js": "^0.8.4"
  },
  "devDependencies": {
    "@angular/cli": "^1.2.7",
    "@angular/compiler-cli": "^4.0.0",
    "@types/jasmine": "2.5.38",
    "@types/node": "~6.0.60",
    "@angular/platform-browser": "^4.0.0",
    "@angular/platform-browser-dynamic": "^4.0.0",
    "@angular/router": "^4.0.0",
    "@ngui/datetime-picker": "^0.16.2",
    "angular2-modal": "^3.0.1",
    "angular2-text-mask": "^8.0.1",
    "core-js": "^2.4.1",
    "flexboxgrid": "^6.3.1",
    "moment": "^2.18.1",
    "ng-select": "^1.0.0-beta.5",
    "ng2-pagination": "^2.0.2",
    "ng2-toastr": "^4.1.0",
    "rxjs": "^5.1.0",
    "zone.js": "^0.8.4"
  }
}

如何在不损坏代码的情况下将其更新为角5？上一次我试图更新它时，有些代码停止工作。我会非常感谢每一个愿意帮忙的人。

要升级你的应用程序，我推荐这个朗读

简而言之，您应该运行：

npm install @angular/{animations,common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router}@5.0.0 

您可以使用任何版本的5.x替换@5.0.0。

您需要的另一件事是将类型记录更新为2.4.2，将RxJS更新为5.5.2

npm install typescript@2.4.2 rxjs@5.5.2
