Question

我正在尝试将Karma和Jasmine集成到我的前端应用程序中，该应用程序目前位于Angular4和webpack上。我应该将所有包升级到最新版本吗？例如，我正在使用webpack1.x，typings，typescript 2.0.3等...我应该将它们分别升级到webpack2，@types和typescript@latest ？

当我查看Angular的package.json时，我发现他们正在使用Webpack1.x。但{@ 1}}已被弃用，webpack鼓励大家切换到v2。

所有上述包装都与包装相关;例如，当使用webpack1时，我应该使用typescript2代替@types和typings代替1.x吗？

您手动更新依赖项的最佳选择是运行npm update，现在我认为没有必要，因为Angular会在必要时要求更新对等项依赖项（并且会通知您！）。

如果您想了解当前的依赖结构：

{
  "name": "proj",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "^4.2.4",
    "@angular/common": "^4.2.4",
    "@angular/compiler": "^4.2.4",
    "@angular/core": "^4.2.4",
    "@angular/forms": "^4.2.4",
    "@angular/http": "^4.2.4",
    "@angular/platform-browser": "^4.2.4",
    "@angular/platform-browser-dynamic": "^4.2.4",
    "@angular/router": "^4.2.4",
    "core-js": "^2.4.1",
    "rxjs": "^5.4.2",

  },
  "devDependencies": {
    "@angular/cli": "1.3.0-rc.3",
    "@angular/compiler-cli": "^4.2.4",
    "@angular/language-service": "^4.2.4",
    "@types/jasmine": "~2.5.53",
    "@types/jasminewd2": "~2.0.2",
    "@types/node": "~6.0.60",
    "codelyzer": "~3.1.1",
    "jasmine-core": "~2.6.2",
    "jasmine-spec-reporter": "~4.1.0",
    "karma": "~1.7.0",
    "karma-chrome-launcher": "~2.1.1",
    "karma-cli": "~1.0.1",
    "karma-coverage-istanbul-reporter": "^1.2.1",
    "karma-jasmine": "~1.1.0",
    "karma-jasmine-html-reporter": "^0.2.2",

    "ts-node": "~3.2.0",
    "tslint": "~5.3.2",
    "typescript": "~2.3.3"
  }
}

并运行npm update以更新到您的配置允许的最新软件包。
