【问题描述】：
我有一个现有的 Angular 2 项目，我正在尝试开始将一些 D3.js 集成到我的项目中。我是 Angular 的新手，这将是我第一次使用 D3。我会关注这个教程：https://keathmilligan.net/create-reusable-chart-components-with-angular-2-and-d3-js-version-4/
我正在运行命令npm install --save d3，我得到：
├── UNMET PEER DEPENDENCY @angular/compiler@2.2.3
├── UNMET PEER DEPENDENCY @angular/compiler-cli@2.2.3
├── UNMET PEER DEPENDENCY @angular/core@2.2.3
└── d3@4.4.1
...然后
npm WARN @ngtools/webpack@1.2.1 requires a peer of @angular/compiler@^2.3.1 but none was installed.
npm WARN @ngtools/webpack@1.2.1 requires a peer of @angular/compiler-cli@^2.3.1 but none was installed.
npm WARN @ngtools/webpack@1.2.1 requires a peer of @angular/core@^2.3.1 but none was installed.
npm WARN @ngtools/webpack@1.2.1 requires a peer of @angular/tsc-wrapped@^0.5.0 but none was installed.
npm WARN tslint-loader@2.1.5 requires a peer of tslint@^3.0.0 but none was installed.
首先，当我看到"UNMET PEER DEPENDENCY" 时，我想我仍然不太清楚它的真正含义。这只是一个警告，还是表明某些东西真的坏了？我的项目目前正在运行（但我还没有开始使用 D3 编码）......仅仅是安装了错误的版本吗？我已经通过npm update --save 采取了更新所有内容的步骤，NPM 确实为我找到了一些更新，但我仍然遇到同样的问题。
我的主要问题是，我正在安装 D3js，那不应该完全独立于 Angular 吗？当我安装一些不相关的东西时，为什么 NPM 对 Angular 的东西大喊大叫？
这是我的 package.json 帖子更新：

【问题讨论】：
-
在未满足对等依赖后，控制台应打印类似
angular requires a peer of angular.v.x but angular.v.x was installed instaed的内容，您能否将其添加到您的问题中？ -
好的，添加了 npm 警告。
