您可以更改@angular版本使用插入符号范围，故宫将安装最新的包到下一个主要版本。

"dependencies": { 
    "@angular/common": "^2.2.1", 
    "@angular/compiler": "^2.2.1", 
    "@angular/core": "^2.2.1", 
    "@angular/forms": "^2.2.1", 
    "@angular/http": "^2.2.1",

此外，它会值得更新到最新的角度版本。有关说明，请参阅here。

你在这里的主要问题是，NPM更新将只更新到每个模块的最新兼容版本与在指定的package.json最高版本的限制。

做到这一点，最安全的办法是更新您的package.json有对未成年和接插部分通配符。 Angular 2（与角1相反）使用semVer（http://semver.org/），因此您可以安全地通配次要和补丁部分。

"@angular/common": "2.*.*", 
"@angular/compiler": "2.*.*", 
"@angular/core": "2.*.*", 
"@angular/forms": "2.*.*", 
"@angular/http": "2.*.*", 
"@angular/material": "^2.0.0-alpha.11-3", 
"@angular/platform-browser": "2.*.*", 
"@angular/platform-browser-dynamic": "2.*.*", 
"@angular/router": "3.0.0",

运行NPM更新/ NPM重新安装，你应该升级。
