如果"ng-template"是一个Web组件，则在此组件中添加"CUSTOM_ELEMENTS_SCHEMA"以禁止显示此消息。("[错误 ->]<ng-template>

Question

zone.js@0.6.25？main=browser：355 未处理的承诺拒绝： 模板解析错误： "ng-template"不是一个已知的元素： 1. 如果"ng-template"是 Angular 组件，请验证它是否是此模块的一部分。 2. 如果"ng-template"是 Web 组件，则将"CUSTOM_ELEMENTS_SCHEMA"添加到该组件的"@NgModule.schemas"以禁止显示此消息。("[错误 ->] ;任务：承诺;值：错误：模板分析错误： "ng-template"不是一个已知的元素：

我已经在我的应用程序模块中应用了这个修复程序：

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 ]
})

<ng-template>是在

Angular4中引入的。

用户<template>或<ng-container>

参见

• https://github.com/angular/angular/issues/15860

Answer 2

1. 更新角度 cli：https://github.com/angular/angular-cli/wiki/stories-1.0-update
2. 更新打字稿和(可选(@angular包。您的包裹很落后，最重要的是angular-cli，所以要做好准备。
   • 我的核心软件包：

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"
}

3. npm install @angular/material && npm install hammerjs —-save
   • 在angular-cli.json中添加/node_modules/hammerjs/hammer.js
4. MaterialModule已弃用 https://github.com/angular/material2/releases
   • 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
   中即可
