I have an existing Angular 2 project and am trying to start integrating some D3.js into my project. I am new to Angular and this will be my first step when using D3. I will follow this guide: https://keathmilligan.net/create-reusable-chart-components-with-angular-2-and-d3-js-version-4/
I run the npm install --save d3 and I get:
├── 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
... then
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.
Firstly, I think I still don’t quite understand what it means when I see "UNMET PEER DEPENDENCY" . Is this just a warning, or does it indicate that something is really broken? My project is currently working (but I haven't started coding with D3 yet) ... Is the wrong version of something just installed? I followed all the steps to update everything through npm update --save , and NPM found some updates for me, but I still have the same problem.
My main question though, I am installing D3js, shouldn't it be completely independent of Angular? Why does NPM bark about Angular things when I install something unrelated?
Here is my post about updating package.json:
