**中的错误不是NgModule [英] ERROR in ** is not an NgModule

问题描述

我有这个NgModule:

I have this NgModule:

@NgModule({
    imports: [
        CommonModule
    ],
    exports: [
        SP21LoadingBar
    ],
    declarations: [SP21LoadingBar]
})
export class SP21LoadingBarModule { }

客户告诉我

ERROR in SP21LoadingBarModule is not an NgModule

请注意:如果我接受代码并将其放入我的项目中，它将可以正常工作.但是，一旦我从项目中取出模块(和组件)并将其放入npm包中，我就会收到该错误.

Please notice: If i take the code and put it into my project it works fine. But as soon as I take the module (and component) out of my project and put it into a npm package, i get that error.

Angular在2.3.1中使用， Angular CLI 1.0.0-beta.24， 打字稿2.0.10

Angular is used in 2.3.1, Angular CLI 1.0.0-beta.24, Typescript 2.0.10

推荐答案

最终解决方案:

必须使用Ahead-Of-Time编译器(ngc)编译库.它将添加一些元数据，以分配包含该库的项目来读取它.

You must compile your library using the Ahead-Of-Time compiler (ngc). It will add some metadata that allos the project that includes the library to read it.
