我正在尝试创建一个角度库项目,但我在控制台中收到此错误
Uncaught TypeError: Cannot read property 'id' of undefined
at registerNgModuleType (core.js:34470)
at core.js:34488
at Array.forEach (<anonymous>)
at registerNgModuleType (core.js:34484)
at new NgModuleFactory$1 (core.js:34651)
at compileNgModuleFactory__POST_R3__ (core.js:40286)

at __webpack_require__ (bootstrap:79)
at Object.0 (main.ts:12)
我创建了一个新的 Angular 项目,ng new --enable-ivy
然后添加了一个带有ng g library my-lib
. 我的图书馆有一个带有模块(如下)的辅助端点,因此导入将是import { MyLibModule } from 'my-lib/secondary';
@NgModule({
imports: [
CommonModule
],
declarations: [
MyLibDirective
],
exports: [
MyLibDirective
]
})
export class MyLibModule {
public static forRoot(): ModuleWithProviders {
return {
ngModule: MyLibModule,
providers: []
};
}
}
我使用ng build my-lib
它构建它,所有构建都很好,我使用链接将库包含在演示应用程序中,在我运行的库的 dist 文件夹和我运行yarn link
的根演示应用程序文件夹中yarn link my-lib
,然后在导入中包含模块这AppModule
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MyLibModule } from 'my-lib/secondary';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
MyLibModule.forRoot()
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
但是,当我运行yarn start
或ng serve
一切正常但我在控制台中收到上述错误时,在浏览器中调试它会显示ngModuleDef
我的库模块中的属性不存在,有谁知道为什么会发生这种情况?
注意:如果我关闭 Ivy,这不是问题,但随着 ng9 即将推出,这不是一个真正可行的解决方案,我想知道我在库中做错了什么(如果有的话)
