ERROR in "path" Module not found: Error: Can't resolve - Angular 6 Webpack
问题
I'm having some problems with webpacking a project in angular 6, when I run "node_modules.bin\webpack" I get the following error:
> ERROR in ./src/app/template/header/header.component.ts Module not
> found: Error: Can't resolve 'src/app/services/authentication.service'

> ./src/app/app.module.ts @ ./src/main.ts
I have no idea why this is happening, when I build or run normally, it works just fine. I've made a simple project, configured everything again, and it worked just fine, but it can't in this project.

已解决更改自动路径：
从：
import { LocalStorageService } from 'src/app/services/local-storage.service';
import { AuthenticationService } from 'src/app/services/authentication.service';
到
import { LocalStorageService } from '../../services/local-storage.service';
import { AuthenticationService } from '../../services/authentication.service';
英文:
Solved changing auto paths:
from:
import { LocalStorageService } from 'src/app/services/local-storage.service';
import { AuthenticationService } from 'src/app/services/authentication.service';
to
import { LocalStorageService } from '../../services/local-storage.service';
import { AuthenticationService } from '../../services/authentication.service';

如果不是自动导入的路径问题，您可能需要执行npm install来安装缺失的模块。
英文:
If it isn't the auto imported paths, you might need to npm install your the missing module.
