Question

今天，我已将Angular / material从9.2.0-next更新为9.2.4，在ng服务之后，我得到了这一点：

platform.js:78 Uncaught TypeError: Class constructor Platform cannot be invoked without 'new'
    at Module../node_modules/@angular/cdk/__ivy_ngcc__/fesm2015/platform.js (platform.js:78)
    at __webpack_require__ (bootstrap:84)
    at Module../node_modules/@angular/cdk/__ivy_ngcc__/fesm2015/a11y.js (a11y.js:1)
    at __webpack_require__ (bootstrap:84)
    at Module../node_modules/@angular/material/__ivy_ngcc__/fesm2015/core.js (core.js:1)
    at __webpack_require__ (bootstrap:84)
    at Module../node_modules/@angular/material/__ivy_ngcc__/fesm2015/icon.js (icon.js:1)
    at __webpack_require__ (bootstrap:84)
    at Module../src/app/home/home.component.ts (home.component.ts:1)
    at __webpack_require__ (bootstrap:84)

试图删除node_modules文件夹并重新安装，该怎么办？

也通过将 @ angular / cdk更新为9.2.4 来解决（ot卡在github：angular / cdk-builds上），然后用干净的npm i重新安装了所有内容/ p>

更新到9.2.4后，角度/材质崩溃
