我正在一个 angular 项目中进行测试，但在这两个测试文件中出现错误：

https://pastebin.com/bttxWtQT

这是我按 npm test https://pastebin.com/ncTg4WXM时得到的错误

请告诉我你对此的看法

我试过了：

npm install --save @angular/material

npm install --save @angular/cdk

ng add @angular/material

npm install --save @angular/typings

npm install typings

npm install types

但没有一个工作
