angular - 从 2 更新到 Angular 4。@Angular/core 和 @Angular/http 的 "Unmet Peer Dependencies"

Question

我正在尝试从 Angular 2.3 更新到 Angular 4.0 并按照此处的说明进行操作:

http://webcache.googleusercontent.com/search?q=cache:Xd-ocIKZ0BkJ:angularjs.blogspot.com/2017/03/angular-400-now-available.html+&cd=1&hl=en&ct=clnk&gl=us

在那篇文章中，它说几乎所有我需要做的就是输入这个命令:

npm install @angular/common@latest @angular/compiler@latest @angular/compiler-cli@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 @angular/animations@latest typescript@latest --save

当我这样做时，我得到了这些错误:

+-- UNMET PEER DEPENDENCY @angular/core@4.0.2
+-- UNMET PEER DEPENDENCY @angular/http@4.0.2

我试着为每一个独立地进行“npm 安装”，如下所述:How to solve npm UNMET PEER DEPENDENCY ，但它没有任何好处。我不断收到同样的错误。

有什么建议吗？我在 Windows 上运行 Node 4.5.0 和 npm 3.10.6。

这是我的 package.json:

看来是package.json中提到的node_modules的vresions冲突

使用下面的

"dependencies": {
    "@angular/animations": "^4.0.1",
    "@angular/common": "^4.0.1",
    "@angular/compiler": "^4.0.1",
    "@angular/compiler-cli": "^4.0.1",
    "@angular/core": "^4.0.1",
    "@angular/forms": "^4.0.1",
    "@angular/http": "^4.0.1",
    "@angular/material": "^2.0.0",
    "@angular/platform-browser": "^4.0.1",
    "@angular/platform-browser-dynamic": "^4.0.1",
    "@angular/platform-server": "^4.0.1",
    "@angular/router": "^4.0.1",
     "bootstrap": "^3.3.6",
    "core-js": "^2.4.1",
    "font-awesome": "^4.7.0",
    "rxjs": "5.0.1",
    "systemjs": "0.19.40",
    "typescript": "^2.2.2",
    "zone.js": "^0.8.5"
