UNMET PEER DEPENDENCY D3.js和Angular 2
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。 我将继续学习本教程：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，我想我看到"UNMET PEER DEPENDENCY"时，我仍然不清楚它的真正含义。 这只是一个警告，还是这表明某件事情真的被打破了？ 我的项目目前工作（但我还没有开始用D3编码）......是不是只安装了错误版本的东西？ 我采取了通过npm update --save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，不应该完全独立于Angular吗？ 为什么当我安装一些不相关的东西时，NPM就会嚷嚷Angular的东西？

UNMET PEER DEPENDENCY日志只是警告而非错误。
他们警告你，你正在使用的库， @ngtools/webpack@1.2.1 ，应该使用@angular/compiler@^2.3.1 （更多信息@ngtools/webpack@1.2.1 ^ https://stackoverflow.com/a/22345808/5706293 ），因为我相信你自己弄明白了。
这些库的作者可能会有一些弃用的API，并且可能不支持更高版本中的当前代码，这是您应该升级依赖关系的原因之一。
这并没有回答我所有的问题，但它确实清楚了我得到的警告。 我只是更新了几个包到最新版本。

我也有类似的问题，我遵循了这些步骤
首先，npm install -g @ angular / cli
使用新的英雄应用程序创建新项目
进入项目文件夹并运行服务器之后
并打开浏览器并运行http：// localhost：4200
这是我的工作..希望同样的事情为你工作
