回答1:

You need to add BrowserModule

@NgModule(
  imports: [BrowserModule, /* other imports */],
  ...
)

If it is in a child module import CommonModule.

import { CommonModule } from "@angular/common"

回答2:

If you already have the CommonModule/BrowserModule and it's still not working, also make sure you typed the attribute correctly. I had ngclass instead of ngClass (notice the 'C').

回答3:

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

...

imports: [CommonModule],
