刚安装了Angular2 beta 11，npm install angular2 --save并收到以下警告：

d:\Projects\sample>npm install angular2 --save
[email protected] d:\Projects\sample
+-- [email protected]
+-- UNMET PEER DEPENDENCY es6-promise@^3.0.2
+-- UNMET PEER DEPENDENCY es6-shim@^0.35.0
+-- UNMET PEER DEPENDENCY [email protected]
+-- UNMET PEER DEPENDENCY [email protected]
`-- UNMET PEER DEPENDENCY zone.js@^0.6.4

npm WARN [email protected] requires a peer of es6-promise@^3.0.2 but none was installed.
npm WARN [email protected] requires a peer of es6-shim@^0.35.0 but none was installed.
npm WARN [email protected] requires a peer of [email protected] but none was installed.
npm WARN [email protected] requires a peer of [email protected] but none was installed.
npm WARN [email protected] requires a peer of zone.js@^0.6.4 but none was installed.

以前的Angular2版本es6-promise es6-shim rxjs zone.js在main中安装了依赖项，package.js但现在没有。

"dependencies": {
    "angular2": "^2.0.0-beta.11"
  }

我检查了..\node_modules\angular2\package.json，可以看到它依赖于以下软件包：

    "peerDependencies": {
    "es6-promise": "^3.0.2",
    "es6-shim": "^0.35.0",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.2",
    "zone.js": "^0.6.4"
  },

有什么想法吗？

看起来答案在这里https://github.com/npm/npm/issues/6565

NPM 3倍：

如果peerDependencies还不是依赖项或devDependency，则将不再隐式安装它们。这是最大的变化，也是最有可能需要开发人员干预的部分。

无效或丢失的peerDependencies将是警告而不是错误。这意味着将使开发人员可以解决有peerDependencies的不正常情况，但是peerDependency的不兼容性应减少对用户的痛苦，因为安装会因依赖关系问题而获得的援助的频率大大降低。
