我使用Angular 9和最新版本的材料进行了一个新项目。当我导入一些Material的类时,出现此错误:
node_modules/@angular/material/form-field/label.d.ts:10:22中的错误-错误NG6002:出现在MaterialModule的NgModule.imports中,但无法解析为NgModule类。
这可能意味着声明cc的MatLabel库(@ angular / material / form-field)未被ngcc正确处理,或者与Angular Ivy不兼容。检查是否有较新版本的库,如果有,则进行更新。还可以考虑与该库的作者进行检查,以查看该库是否与Ivy兼容。
10个导出声明类MatLabel { ~~~~~~~~~ node_modules/@angular/material/form-field/hint.d.ts:20:22-错误NG6002:出现在MaterialModule的NgModule.imports中,但无法解析为NgModule类。
这可能意味着ngcc尚未正确处理声明MatHint的库(@ angular / material / form-field),或与Angular Ivy不兼容。检查是否有较新版本的库,如果有,则进行更新。还可以考虑与该库的作者进行检查,以查看该库是否与Ivy兼容。
20 export声明类MatHint { ~~~~~~~ src / app / material.module.ts:12:14-错误NG6002:出现在AppModule的NgModule.imports中,但无法解析为NgModule类。
是否缺少@NgModule注释?
12个导出类MaterialModule {} ~~~~~~~~~~~~~~

我试图删除node_modules并重新安装。另外,我将Angular版本更新为10,然后将Material版本更新为Material版本,但是问题仍然存在。
我查看了其他类似问题,但没有一种解决方案可以解决我的问题。

MatLabel和MatHint包含在MatFormFieldModule中,您不必导入它们。按照in the documentation
的说明仅导入MatFormFieldModuleimport {MatFormFieldModule} from '@angular/material/form-field';
@NgModule({
imports: [MatFormFieldModule],
exports: [MatFormFieldModule],
})
