角材料。导入 MatIconRegistry 时出错

Question

我正在使用“Angular: 10.0.14”和“@angular/material 10.2.7”，在尝试导入 MatIconRegistry 时出现此错误。

node_modules/@angular/material/icon/icon-registry.d.ts:51:22 中的错误 - 错误 NG6002：出现在 MaterialModule 的 NgModule.imports 中，但无法解析为 NgModule 类。

This likely means that the library (@angular/material/icon) which declares MatIconRegistry has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

51 export declare class MatIconRegistry implements OnDestroy {
                        ~~~~~~~~~~~~~~~
node_modules/@angular/material/icon/icon-registry.d.ts:51:22 - error NG6003: Appears in the NgModule.exports of MaterialModule, but could not be resolved to an NgModule, Component, Directive, or Pipe class.

通过从我的材质模块中删除 MatIconRegistry 的导入并将其导入我想要使用它的组件中，问题已得到解决。
