Angular CLI에서 피어 종속성 설치를 어떻게 처리합니까?

Angular CLI에서 피어 종속성 설치를 어떻게 처리합니까?

---

Angular CLI 및 NPM을 업데이트하려고 할 때 거의 끝이없는 오류주기를 발견했습니다. 업데이트 할 때마다 피어 종속성 (아래 참조)을 설치하라는 WARN 메시지가 표시되지만 종속성을 설치할 때마다 더 많은 WARN 메시지가 표시됩니다. 이 상황을 처리하는 더 좋은 방법이 있습니까 아니면 심각하게 몇 시간이 걸리나요?

내가 뭔가 잘못하고 있다는 것을 알고 있지만 Angular를 처음 사용합니다.

피어 종속성 경고는 대개 무시할 수 있습니다. 조치를 취해야하는 유일한 시간은 피어 종속성이 완전히 누락되었거나 피어 종속성 버전이 설치 한 버전보다 높은 경우입니다.

이 경고를 예로 들어 보겠습니다.

npm WARN @angular/animations@5.2.1 requires a peer of @angular/core@5.2.1 but none is installed. You must install peer dependencies yourself.

With Angular, you would like the versions you are using to be consistent across all packages. If there are any incompatible versions, change the versions in your package.json, and run npm install so they are all synced up. I tend to keep my versions for Angular at the latest version, but you will need to make sure your versions are consistent for whatever version of Angular you require (which may not be the most recent).

In a situation like this:

npm WARN ngx-carousel@1.3.5 requires a peer of @angular/core@^2.4.0 || ^4.0.0 but none is installed. You must install peer dependencies yourself.

If you are working with a version of Angular that is higher than 4.0.0, then you will likely have no issues. Nothing to do about this one then. If you are using an Angular version under 2.4.0, then you need to bring your version up. Update the package.json, and run npm install, or run npm install for the specific version you need. Like this:

npm install @angular/core@5.2.3 --save

You can leave out the --save if you are running npm 5.0.0 or higher, that version saves the package in the dependencies section of the package.json automatically.

In this situation:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.3 (node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

You are running Windows, and fsevent requires OSX. This warning can be ignored.

Hope this helps, and have fun learning Angular!

You can ignore the peer dependency warnings by using the --force flag with Angular cli when updating dependencies.

ng update @angular/cli @angular/core --force
