javascript - 如何将 @Gbuomprisco/ng2-tag-input 与 angular-cli 一起使用？

Question

我正在使用最新版本的 @angular/cli (1.0.0-beta.32.3)，并且我正在尝试使用 ng2-tag-input 。 当我启动 ngserve 命令时，出现此错误:

ERROR in Error encountered resolving symbol values statically. Only initialized variables and constants can be referenced because the value of this variable is needed by the template compiler (position 5:22 in the original .ts file), resolving symbol Ng2DropdownModule in my-project/node_modules/ng2-tag-input/dist/node_modules/ng2-material-dropdown/index.d.ts, resolving symbol TagInputModule in my-project/node_modules/ng2-tag-input/dist/modules/ng2-tag-input.module.d.ts, resolving symbol TagInputModule in my-project/node_modules/ng2-tag-input/dist/modules/ng2-tag-input.module.d.ts
webpack: Failed to compile.

知道如何解决这个问题吗？

这是我的 package.json:

    "ts-node": "1.2.1",

    "typescript": "~2.0.3"
  }
}

和我的app.module.ts

import { BrowserModule } from "@angular/platform-browser";
import { NgModule } from "@angular/core";
import { FormsModule } from "@angular/forms";
import { HttpModule } from "@angular/http";
import { TagInputModule } from 'ng2-tag-input';
import { RouterModule } from "@angular/router";
import { ROUTES } from "./app.routes";
import { AppComponent } from "./app.component";

@NgModule({
  declarations: [ AppComponent ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    TagInputModule,
    RouterModule.forRoot(ROUTES, { useHash: true })
  ],
  providers: [ ],
  bootstrap: [AppComponent]
})
export class AppModule {
}

感谢您的帮助!

正如 Galvan 所建议的，使用 ng2-tag-input 0.8.6 版本拯救了我的一天(谢谢!)。

npm i ng2-tag-input@0.8.6 --save

我已提交 issue这样他们就可以更新 npm 注册表
