推荐答案

发现此错误可能是由于组件已在多个模块(例如，在app.module和my_feature_module.module中)注册的缘故.

Found this error can be caused by components being registered in multiple modules, for example in app.module and my_feature_module.module.

暂时禁用tsconfig.json -> fullTemplateTypeCheck并重新运行ng build --prod可能会显示相关的组件注册错误.

Temporarily disabling tsconfig.json -> fullTemplateTypeCheck and re-running ng build --prod might show the related component registration errors.
