Can't use ionic native

Ionic Native
1

I have this Ionic 3 app and i want to use the camera. I need to install Ionic Native for that.

When i try to install I get this

Joaos-MacBook-Pro-3:Escolando joaogarcia$ npm install @ionic-native/core --save
(node:2150) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.
Escolando@0.0.1 /Users/joaogarcia/Documents/BitBucket/escolando-family/Escolando
├── UNMET PEER DEPENDENCY @angular/core@4.4.3 invalid
└── @ionic-native/core@4.5.2

npm WARN @angular/animations@5.1.0 requires a peer of @angular/core@5.1.0 but none was installed.

Or when i try to the camera:

Joaos-MacBook-Pro-3:Escolando joaogarcia$ npm install @ionic-native/camera --save
(node:2235) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.

└── @ionic-native/camera@4.5.2

npm WARN @angular/animations@5.1.0 requires a peer of @angular/core@5.1.0 but none was installed.

I’m missing something?

also i get this warning when i try any of the above:

npm WARN @angular/animations@5.1.0 requires a peer of @angular/core@5.1.0 but none was installed.

And Im following this tutorial:
https://ionicframework.com/docs/native/

What is the error? The stuff you posted are pretty normal warnings, nothing else.

I thought that meant the libraries were not installed
