Can't install Angular 1.5 component router

Question

I'm trying to install the Angular 1.5 component router for use in a new project, but having a lot of difficulty. As per https://docs.angularjs.org/guide/component-router, the following should work:

npm install @angular/router --save

Here's what I see:

$ npm install @angular/router --save
npm ERR! Darwin 14.5.0
npm ERR! argv "/Users/JonathanM/.nvm/versions/node/v4.4.2/bin/node" "/Users/JonathanM/.nvm/versions/node/v4.4.2/bin/npm" "install" "@angular/router" "--save"
npm ERR! node v4.4.2
npm ERR! npm  v3.8.6
npm ERR! code E400

npm ERR! 400 Bad Request

npm ERR! Please include the following file with any support request:
npm ERR!     /Users/JonathanM/Workspace/my-angular-app/npm-debug.log

With node v4.4.2 and npm v3.8.6.

I feel like I'm on the wrong version of npm or something, because I also can't install angular with the syntax they mention in the docs (npm [email protected] angular --save). When I try, I get a generic Usage: npm <command> error, like it doesn't even recognize the command.

Am I doing something wrong? Did the package(s) get pulled/moved? Any help would be appreciated.

As @PeteBD suspected in his comment, I was pointing to a private npm repo. I was able to successfully install the router with:

npm config set registry https://registry.npmjs.org/
npm install @angular/router --save
