Angular 10：尝试导入模块时找不到名称

Question

I created a new Angular project and a new module inside that project using the CLI. If I try to import the newly created module in app.module.ts the Intellisense doesn't work and it can't find the module to auto-import it. I didn't change anything inside the tsconfig.json files.

• Angular CLI: 10.0.4
• Node: 12.16.3
• Angular: 10.0.5
• Typescript: 3.9.7
• VS Code: 1.47.3

Any idea what could cause it?

EDIT: A manual import works fine, but I'm asking about the auto-import functionality.

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';



@NgModule({
  declarations: [],
  imports: [
    CommonModule
  ]
})
export class TestModule { }

Answer 1

I found the source of the problem in the tsconfig.json inside the project's root folder.

{
  "files": [],
  "references": [
    {
      "path": "./tsconfig.app.json"
    },
    {
      "path": "./tsconfig.spec.json"
    }
]
}

If you just change it to this

{
  "extends": "./tsconfig.base.json"
}

VS Code auto-import starts working

As I understand it the main problem is "files": [], typescript stops seeing all files that are not included in the project.

Try exporting child components inside Testmodule like this

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