error installing 3rd party Packages via npm for angular4

Question

I have tried to install angular2-datatable and loadash via

npm install --save angular2-datatable

and

sudo npm i --save lodash

but this error

reporter-ui@0.0.0 /Users/.../Desktop/reporter-ui
├── UNMET PEER DEPENDENCY @angular/common@4.2.3
├── UNMET PEER DEPENDENCY @angular/core@4.2.3
├── UNMET PEER DEPENDENCY @angular/platform-browser@4.2.3
└── angular2-datatable@0.6.0 

npm WARN angular2-datatable@0.6.0 requires a peer of @angular/core@^2.0.0 but none was installed.
npm WARN angular2-datatable@0.6.0 requires a peer of @angular/common@^2.0.0 but none was installed.
npm WARN angular2-datatable@0.6.0 requires a peer of @angular/platform-browser@^2.0.0 but none was installed.

showed up both times. how do I update these dependencies? if I do a ng --version

angular-cli: 1.0.0-beta.28.3
node: 7.10.0
os: darwin x64
@angular/animations: 4.2.3
@angular/common: 4.2.3
@angular/compiler: 4.2.3
@angular/core: 4.2.3
@angular/forms: 4.2.3
@angular/http: 4.2.3
@angular/material: 2.0.0-beta.6
@angular/platform-browser: 4.2.3
@angular/platform-browser-dynamic: 4.2.3
@angular/router: 4.2.3
@angular/cli: 1.1.0
@angular/compiler-cli: 4.2.3
@angular/language-service: 4.2.3

and I have tried to manually change the versions to the correct ones in my package.json but I'm still getting the error. it seems to me that the correct versions are installed, but how do I tell the angular cli and or npm that? Also, I have tried upgrading npm and the angular cli still the same error.

After Further investigation, the error that was being generated was unrelated to the stated warnings. as stated by the comments, these warnings can be ignored, everything is working as expected.
