"dependencies": {
    "@angular/common": "^2.0.0-rc.4",
    "@angular/compiler": "^2.0.0-rc.4",
    "@angular/core": "^2.0.0-rc.4",
    "@angular/http": "^2.0.0-rc.4",

Answer 1

angular-router有rc版本，直到3喜欢＆＃34; @ angular / router＆＃34;：＆＃34; ^ 2.0.0-rc.3＆＃34;，

在那个版本之后，他们单独发布角度/路由器作为beta版本，如

"@angular/router":"3.0.0-beta.2"

Answer 2

最新的路由器版本为3.0.0-beta.2

https://github.com/angular/angular/blob/master/modules/%40angular/router/CHANGELOG.md

未找到兼容版本：安装angular2 RC4路由器时出现@ angular / router @ ^ 2.0.0-rc.4错误
