Is this a regression?

I am not sure. Up until I ran npm insatll to update some other dependencies other than angular ones, I did not encounter any problem.

Description

The project was running successfully until I ran npm install to update a few dependencies and resolve some vulnerabilities. Then the project just broke and told me that all the imports starting with src/ failed.

🔬 Minimal Reproduction

I have a tutorial project here. You may just clone it and run ng serve.

Anything else relevant? I tried to resolve the issue by fixing the version mismatch between @angular/compiler and @angular/compiler-cli as it was prompted after the npm install, saying that npm WARN @angular/compiler-cli@7.1.4 requires a peer of @angular/compiler@7.1.4 but none is installed. You must install peer dependencies yourself. Not helping at all, if not making things worse…

What caused my problem is { "compilerOptions": { "baseUrl": "./"}} being set in the tsconfig.app.json file which is inside the src folder.
Removing it or specifying it to the parent folder fixed it.

Hi, looking at your code base, this is working as intended.

As imports to local modules need to be relative to the file that is importing them example in https://github.com/HymanZHAN/EventBoard/blob/052f175dc5ec51643627aeb22a6d156fe891b53b/src/app/_services/event.service.ts#L6 and not absolute.

import { environment } from 'src/environments/environment';

Should be

import { environment } from '../../environments/environment';
