【问题描述】：
我一直在关注 Angular 2 路由和导航示例，该示例可在此链接中找到：https://plnkr.co/edit/I4ArEQTniO7MJtfzpBWl?p=info。
当我运行转译器时，我收到错误消息：“client/app/app.module.ts(5,41): error TS2307: Cannot find module '@angular/platform-browser/animations'。”
根据我的 systemjs.config.js（如下所示），我希望模块“@angular/platform-browser/animations”是位于 node_modules 中的文件“platform-browser-animations.umd.js” /@angular/platform-browser/bundles，但它不存在。
//systemjs.config.js
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
'@angular/animations': 'npm:@angular/animations/bundles/animations.umd.js',
'@angular/animations/browser': 'npm:@angular/animations/bundles/animations-browser.umd.js',
'@angular/core': 'npm:@angular/core/bundles/core.umd.js',
'@angular/common': 'npm:@angular/common/bundles/common.umd.js',
'@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
'@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
'@angular/platform-browser/animations': 'npm:@angular/platform-browser/bundles/platform-browser-animations.umd.js',
'@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
'@angular/http': 'npm:@angular/http/bundles/http.umd.js',
'@angular/router': 'npm:@angular/router/bundles/router.umd.js',
'@angular/router/upgrade': 'npm:@angular/router/bundles/router-upgrade.umd.js',
'@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
'@angular/upgrade': 'npm:@angular/upgrade/bundles/upgrade.umd.js',
'@angular/upgrade/static': 'npm:@angular/upgrade/bundles/upgrade-static.umd.js',
// other libraries
'rxjs': 'npm:rxjs',
'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
//app: {
// main: './main.js',
// defaultExtension: 'js'
//},
client: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
}
}
});
})(this);
我尝试使用 npm 安装缺少的框架，但收到未满足的依赖错误消息：
+-- UNMET PEER DEPENDENCY @angular/common@2.4.8
+-- UNMET PEER DEPENDENCY @angular/core@2.4.8
`-- UNMET PEER DEPENDENCY @angular/platform-browser@2.4.10
然后我尝试安装依赖版本，但继续收到未满足的依赖消息。
>npm install @angular/common@2.4.8 @angular/core@2.4.8 @angular/platform-browser@2.4.10 --save
我注意到一个警告表明我应该安装 Angular 4。
npm WARN @angular/animations@4.0.0 requires a peer of @angular/core@4.0.0 but no
ne was installed.
看起来我安装了动画 4.0，它需要我不想安装的核心 4.0。我需要卸载动画 4.0 并安装早期版本的动画吗？我的 package.json 文件如下。

看起来问题可能与我的动画版本有关？如果您同意，如何卸载现有版本以及我应该安装与我拥有的@angular/core 2.4.8 版本兼容的版本。如果这不是问题，我该如何安装丢失的文件 @angular/platform-browser/bundles/platform-browser-animations.umd.js？
