如果 'ng-template' 是 Web 组件，则添加“CUSTOM_ELEMENTS_SCHEMA"；到此组件的 以抑制此消息.("[错误 ->]<ng-template>

问题描述

zone.js@0.6.25?main=browser:355 未处理的 Promise 拒绝:模板解析错误:'ng-template' 不是已知元素:1. 如果 'ng-template' 是一个 Angular 组件，那么验证它是否是这个模块的一部分.2. 如果'ng-template' 是一个Web 组件，则将CUSTOM_ELEMENTS_SCHEMA"添加到该组件的'@NgModule.schemas' 以抑制此消息.("[ERROR ->] ; 任务:Promise.then ; 值:错误:模板解析错误:'ng-template' 不是已知元素:

我已经在我的 App.module.ts 中应用了这个修复:

I have applied this FIX in my App.module.ts:

import { NgModule, CUSTOM_ELEMENTS_SCHEMA ,NO_ERRORS_SCHEMA}  from '@angular/core';


@NgModule({
    imports: [
        BrowserModule,
        FormsModule,
        ReactiveFormsModule,
        HttpModule,
        JsonpModule,
        CKEditorModule,
        Ng2DatetimePickerModule,
        Ng2DragDropModule,
        DragulaModule,
        ModalModule.forRoot(),
        MaterialModule.forRoot(),
        BootstrapModalModule,
        RouterModule.forRoot(appRoutes, {useHash: true})
    ],
    declarations: [something
    ],
    providers: [],
    bootstrap: [AppComponent],
    schemas: [ CUSTOM_ELEMENTS_SCHEMA, NO_ERRORS_SCHEMA ]
})

即使在此之后它也不起作用.

Even after this it is not working.

推荐答案

1. 更新angular-cli:https://github.com/angular/angular-cli/wiki/stories-1.0-update
2. 更新打字稿和可选的 @angular 包.你的包相当落后，最重要的是 angular-cli，所以要做好准备.
   • 我的核心包:

1. Update angular-cli: https://github.com/angular/angular-cli/wiki/stories-1.0-update
2. Update typescript and optionally your @angular packages. Your packages are pretty behind, most importantly angular-cli, so be prepared.
   • My core packages:

dependecies: {
  "@angular/animations": "^4.0.2",
  "@angular/common": "^2.3.1",
  "@angular/compiler": "^2.3.1",
  "@angular/compiler-cli": "^2.4.10",
  "@angular/core": "^2.3.1",
  "@angular/forms": "^2.3.1",
  "@angular/http": "^2.3.1",
  "@angular/material": "^2.0.0-beta.3",
  "@angular/platform-browser": "^2.3.1",
  "@angular/platform-browser-dynamic": "^2.3.1",
  "@angular/platform-server": "^4.0.0",
  "@angular/router": "^3.3.1"
}
devDependencies: {
  "@angular/cli": "^1.0.0",
  "typescript": "^2.2.2"
}

1. npm install @angular/material &&npm installhammerjs ---save
   • 在angular-cli.json
   中添加/node_modules/hammerjs/hammer.js

• 将单个模块导入您的 app.module，并相应地导出，然后只需将标签添加到 html

• import individual modules into your app.module, and export accordingly then simply add tags to html
