Question

如何找出受影响的组件名称是什么？我真的不明白为什么angular会说“ class_1”是组件名称。我正在使用Angular 7.0.0，并且正在进行重构。（将6个组件添加到一个新模块中）

Error: Uncaught (in promise): Error: Component class_1 is not part of any NgModule or the module has not been imported into your module.

我已经解决了这个问题。我删除了路由文件中的每条路由，然后逐一添加，发现模块声明中缺少1个组件。但是我真的不明白为什么angular会说组件名称是“ class_1”，但是我意识到受影响的组件在另一个模块中，因为有2个组件具有相同的名称，而我尝试使用错误的组件。因此，我假设angular在另一个模块中无法获得受影响的组件名称。

组件class_1不属于任何NgModule
