Answer 1

我使用最新的tns-core-modules和nativescript-angular测试了这个场景，一切都按预期工作。正如@ Panayot.Cankov建议您升级到tns-core-modules@2.2.0和nativescript-angular@0.3.0。您可以使用以下命令执行此操作：

tns plugin remove tns-core-modules
tns plugin add tns-core-modules@2.2.0
tns plugin remove nativescript-angular
tns plugin add nativescript-angular@0.3.0

Answer 2

升级tns-core-modules@2.2.0和nativescript-angular@0.3.0。经过一些重构之后，我们在tns-core-modules中的View类中引入了cssClasses Set，但是由于不愉快的巧合，nativescript-angular通过在View类上修补自己的cssClasses Array属性来扩展。它已经解决，但是tns-core-modules的新版本将与旧版本的nativescript-angular不兼容。

确保你也升级你的角度依赖，我收到同样的错误，直到我碰到rc4。以下依赖关系现在适用于我。

"@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",
    "@angular/platform-browser": "2.0.0-rc.4",
    "@angular/platform-browser-dynamic": "2.0.0-rc.4",
    "@angular/platform-server": "2.0.0-rc.4",
    "@angular/router-deprecated": "2.0.0-rc.2",
    "nativescript-angular": "^0.3.0",
    "nativescript-drop-down": "^1.3.2",
    "rxjs": "5.0.0-beta.6",
    "tns-core-modules": "^2.2.1",
    "zone.js": "^0.6.12"

Nativescript 2.2例外
