Angular 由于'@角度/材料'；；错误

在Angular 10上下载以下项目时：

由于以下错误，无法编译：

src/material module.ts:47:8中出错-错误TS2306:File'/Users/ed/tabletest/node_modules/@angular/material/index.d.ts'不是模块

如果我运行ng添加@angular/material

正在跳过安装：是否已安装程序包？选择一个预构建的 主题名称，或自定义主题的“自定义”：深紫色/a成员[ 预览：https://material.angular.io?theme=deeppurple-琥珀色]？设置 全局角度材质排版样式？对设置浏览器 角材质的动画？是更新package.json（1318字节） ✔ 软件包已成功安装。无法读取角度模块文件： /src/undefined.ts

您需要单独导入这些模块：

import { MatSliderModule } from '@angular/material/slider';
import { MatSnackBarModule } from '@angular/material/snack-bar';
import { MatTableModule } from '@angular/material/table';
import { MatTabsModule } from '@angular/material/tabs';
import { MatToolbarModule } from '@angular/material/toolbar';

等等。那么，它应该工作得很好

如果您选中

node\u modules/@angular/material/index.d.ts

，您会看到一个几乎为空的文件，但有一条注释。此文件不导出任何角度材质模块，因此会出现错误

例如

node\u modules/@angular/material/toolbar/index.d.ts

：

/**
 * Generated bundle index. Do not edit.
 */
export * from './public-api';

//# sourceMappingURL=index.d.ts.map

然后在

node_modules/@angular/material/toolbar/public api.d.ts

中找到相应的模块：
