solve
reason:angular版本号 与 material cdk 版本号不匹配。
It can be seen from the official website that there are many versions. Material is installed by default. If the version number is not specified when cdk is installed, the latest version will be installed. But my own angular version is useless and the latest is 8.3.8. That's why the above error is reported.
Finally, you only need to modify the material and cdk version numbers in package.json, and re-npm install to solve the problem.
(My angular8.* uses material, cdk version 8.2.3)
