Question

git repo中有一个包

https://github.com/keephacking/ionic-scrolling-header

有使所有东西兼容的东西。但在用

构建我的应用程序时

ionic build --prod命令，aot build失败，错误如下所示。

[18:02:48]  ngc started ...
[18:02:57]  typescript error
        Unexpected value 'ScrollingHeaderModule in
        xxx/node_modules/ionic-scrolling-header/scrolling-header.module.d.ts' imported by the
        module 'xxxModule in xxx/xxx.module.ts'. Please add a @NgModule
        annotation.

Error: The Angular AoT build failed. See the issues above

我在Package.json中的依赖关系

{
   "dependencies": {
    "@angular/common": "5.2.0",
    "@angular/compiler": "5.2.0",
    "@angular/compiler-cli": "5.2.0",
    "@angular/core": "5.2.0",
    "@angular/forms": "5.2.0",
    "@angular/http": "5.2.0",
    "@angular/platform-browser": "5.2.0",
    "@angular/platform-browser-dynamic": "5.2.0",
    "@ionic-native/core": "4.4.2",
    "@ionic/storage": "2.1.3",
    "es6-promise-plugin": "^4.1.1",

    "@angular/cli": "^1.6.3",
    "@ionic/app-scripts": "3.1.7",
    "typescript": "2.6.2"
  }
}

非常好奇，知道该套餐中缺少什么。

感谢

Answer 1

我按照以下步骤操作，它对我有用，希望它可以帮助你

第1步：安装npm install ionic-scrolling-header --sav-dev

第2步：打开您的home.moduel.ts文件并导入此import {ScrollingHeaderModule} from 'ionic-scrolling-header';，不要忘记在导入中添加此内容

imports: [
    ScrollingHeaderModule,
    IonicPageModule.forChild(HomePage),
  ],

步骤3：在您的home.ts文件中添加此@ViewChild(Content) content: Content;

第4步：在home.html页面中添加此<ion-header [scrollingHeader]='content'>

有关详细信息，请查看此link

我已按照以下步骤进行修复：

0-Download project from author repository
1-Rename "src" folder to "ionic-scrolling-header", and copy to your directive(folder)
2-Create a directive folder inside src (folder)
3-Change import in your app.module.ts, as you can see on my print:

Answer 3

当我的tsconfig.json没有发出声明文件时，我遇到了这个错误。

请确保在构建ScrollingHeaderModule的代码库中的tsconfig.json中包含以下内容：

"declaration": true,

Answer 4

此问题已在最新版本的ionic-scrolling-header程序包中修复。

npm install ionic-scrolling-header@latest将解决它。

Answer 5

离子6.7.0，Corodova 0.14.0

遇到类似问题，尝试了所有操作。...后来发现我在文件 directives.module.ts 中缺少导入类'XYZ'的情况。因此，在该文件以及NgModule声明中添加了import语句。

import {ParallaxHeader} from './parallax-header/parallax-header';
@NgModule({
declarations: [ParallaxHeader],
imports: [],
exports: [ParallaxHeader] })

在`building中使用`--prod`进行离子滚动标题包问题（请添加@NgModule注释。）
