为什么NPM对实际满足的依赖关系给出未满足的依赖关系警告？

Question

我正在尝试使用typescript和node启动并运行angular2，但它总是给我关于未满足的对等依赖的警告。然而，这表明它们是可用的：

tyler@tyler-Blade-Stealth:~/projects/mockups$ npm install -g @angular/core
/usr/share/node/lib
├── @angular/core@2.4.3 
├── UNMET PEER DEPENDENCY rxjs@^5.0.1
└── UNMET PEER DEPENDENCY zone.js@^0.7.2

npm WARN @angular/core@2.4.3 requires a peer of rxjs@^5.0.1 but none was installed.
npm WARN @angular/core@2.4.3 requires a peer of zone.js@^0.7.2 but none was installed.
tyler@tyler-Blade-Stealth:~/projects/mockups$ npm view rxjs | grep version:
  version: '5.0.3',
tyler@tyler-Blade-Stealth:~/projects/mockups$ npm view zone.js | grep version:
  version: '0.7.4',

我怎样才能让这些警告消失呢？

npm view在注册表中显示有关软件包的信息，而不是显示它是否已安装。
