angular - 如何在 Angular CLI 中更新 angular 2

Question

如何更新 Angular 2 版本？我使用 Angular CLI 1.0.0-beta.20-4 并尝试了 npm update --save 但它没有做任何事情。

下面是我目前的 package.json 文件。感谢对此的任何帮助。

您可以更改@angular 版本以使用插入符号范围，以便 NPM 将安装最新的包直到下一个主要版本。

  "dependencies": {
    "@angular/common": "^2.2.1",
    "@angular/compiler": "^2.2.1",
    "@angular/core": "^2.2.1",
    "@angular/forms": "^2.2.1",
    "@angular/http": "^2.2.1",

也值得更新到最新的 angular-cli 版本。参见 here获取说明。
