我检查了你的代码，如果你们中的一个导入了大写的 UserClass，通常会发生这个问题

app.routing.module 中的更改

来自

import { ProductsComponent } from './website/Products/Products.component';
import { ProductsampleComponent } from './website/Products/Productsample/Productsample.component';

到

import { ProductsComponent } from './website/products/products.component';
import { ProductsampleComponent } from './website/products/productsample/productsample.component';
