既然Angular 正在遵循语义版本控制，并且Angular2.4.3 已发布，那么当我在现有项目中升级到下一个 Angular 版本时，我有点困惑什么是最佳实践。

我有一个带有 Angular-cli 的项目，带有@angular/core: 2.2.0. 这是我的package.json：

"dependencies": {
    "@angular/common": "~2.2.0",
    "@angular/compiler": "~2.2.0",
    "@angular/core": "~2.2.0",
    "@angular/forms": "~2.2.0",
    "@angular/http": "~2.2.0",
    "@angular/platform-browser": "~2.2.0",
    "@angular/platform-browser-dynamic": "~2.2.0",
    "@angular/router": "~3.2.0",
    "@types/jasmine": "^2.5.40",
    "angular2-click-outside": "^0.1.0",
    "angular2-modal": "^2.0.2",
    "bootstrap": "4.0.0-alpha.4",
    "bootstrap-loader": "^2.0.0-beta.15",
    "core-js": "^2.4.1",
    "karma-remap-istanbul": "^0.2.2",
    "material-design-icons": "^3.0.1",
    "ng2-bootstrap": "^1.1.16",
    "ng2-charts": "^1.4.4",
    "postcss-loader": "^1.1.1",
    "rxjs": "5.0.0-rc.4",
    "screenfull": "^3.0.2",
    "ts-helpers": "^1.1.1",
    "zone.js": "^0.6.23"
  },
  "devDependencies": {
    "@types/jasmine": "^2.2.30",
    "@types/node": "^6.0.42",
    "angular-cli": "1.0.0-beta.19-3",
    "codelyzer": "1.0.0-beta.3",
    "jasmine-core": "2.5.2",
    "jasmine-spec-reporter": "2.7.0",
    "karma": "1.3.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-cli": "^1.0.1",
    "karma-jasmine": "^1.0.2",
    "karma-remap-istanbul": "^0.2.1",
    "node-sass": "^3.13.0",
    "protractor": "4.0.11",
    "replace": "0.3.0",
    "ts-node": "1.7.0",
    "tslint": "3.15.1",
    "typescript": "~2.0.3",
    "webdriver-manager": "10.2.8"
  }

问题：如何按照最佳实践升级到下一个 Angular 版本（现在：2.4.3 或 4.0.0-beta.3）？使用npm或yarn。

我建议你安装npm-check-updates库。这将让您找到您使用的最新版本的依赖项。

按照步骤：

  1. 安装

    npm i -g npm-check-updates

  1. 要更新您的 package.json：

    npm-检查更新-u

  1. 要安装最新版本的依赖项

    npm 安装

我已将我的应用程序从 Angular 升级2.4.0到4.0.2没有任何代码更改！请记住，尽管这取决于您使用的功能/类/方法。

我跑了

npm i @angular/common@latest @angular/compiler@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest typescript@latest --S -E

然后

npm i @angular/compiler-cli@latest --D -E

注意：@latest如果您想要最新的稳定版本，请使用。如果@next您想要最新的“前沿”版本，请使用。
