从其他仓库导入组件 [英] Import component from a different repo

问题描述

我在bitbucket中创建了一个名为"angular-lister"的存储库，该存储库的结构为:

然后我创建了另一个具有相同结构的存储库(有点，不能在此处放置图片，这并不重要).
在第二个存储库中，我使用 npm i --save path/to/angular-lister.git 安装了存储库，我看到它已添加到程序包json +中，位于我的node_modules文件夹下.

我正在尝试从angular-lister(app/app.component)导入组件，但是我做不到.

这是我第二个存储库的 app.module.ts (没有角度列表):

 从'node_modules/angular-lister/app/app.component'导入{ListerAppComponent}@NgModule({进口:[...]，声明:[...，ListerAppComponent]，引导程序:[...]}) 

，我收到以下错误消息:

zone.js:1382 GET

解决方案

node_modules 应该不存在，因为您已经告诉SystemJS检入该文件夹.只需对此进行

 从'./angular-lister/app/app.component'导入{ListerAppComponent} 

请记住，您不仅可以导入项目，还必须创建一个npm包并导出正确的内容.本教程是了解其工作原理的一个很好的切入点.

I created a repo in bitbucket which called "angular-lister", the structure of the repo is:

Then I created another repo which have the same structure (sort of, cant put picture here and it doesnt really matter).
In this second repo I installed my repo using npm i --save path/to/angular-lister.git and I saw it was added to my package json + it's located under my node_modules folder.

I am trying to import a component from angular-lister (app/app.component) but I am unable to do it.

This is my app.module.ts of the second repo (NOT angular-lister):

import { ListerAppComponent } from 'node_modules/angular-lister/app/app.component'

@NgModule({
    imports:      [
        ...
    ],
    declarations: [
        ...,
        ListerAppComponent
    ],
    bootstrap:    [ ...]
})

and I get the following error:

zone.js:1382 GET http://localhost:3000/node_modules/angular-lister/app/app.component 404 (Not Found)

Why is that, what am I doing wrong here?

})(this);

node_modules/agnular-lister:

解决方案

node_modules should not be there since you are already telling SystemJS to check in that folder. Just edit it by this:

import { ListerAppComponent } from './angular-lister/app/app.component'

Keep in mind that you can't just import the project, you have to create a npm package and export the right thing. this tutorial is a good entrypoint to understand how it works.
