The package [email protected] does not satisfy its siblings' peerDependencies requirements?

Question

I am trying to install @ngrx/store module in my angular 2 app. I am using npm install and getting the following error:

npm ERR! peerinvalid The package [email protected] does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer @angular/[email protected] wants [email protected]
npm ERR! peerinvalid Peer @angular/[email protected] wants [email protected]
npm ERR! peerinvalid Peer [email protected] wants [email protected]
npm ERR! peerinvalid Peer @ngrx/[email protected] wants [email protected]

Does this mean I have to upgrade my angular2 module because it needs a lower version of [email protected]?

Answer 1

The problem is that you have both beta.16 and rc.0 as dependencies in the same project. Since angular changed the npm package name between the two, you will need to uninstall and remove dependencies on whichever one you don't want. Assuming you want to upgrade to the rc.0, remove it from your package.json and run:

npm uninstall angular2

Answer 2

I was on node v 0.12 and upgrading to version 6.9 fixed this

Answer 3

Try running this, it might work for you:

npm install --save @angular/core @angular/compiler @angular/common @angular/platform-browser @angular/platform-browser-dynamic [email protected] [email protected]
