升级Angular项目后,“Uncaught TypeError：Object.setPrototypeOf在null或undefined上调用”

我有一个Angular应用程序,它完美地运行.但是,在使用yarn升级升级依赖项之后,我遇到了这个神秘的错误： @H_676_1@main.bundle.js:6779 Uncaught TypeError: Object.setPrototypeOf called on null or undefined at setPrototypeOf (<anonymous>) at webpackJsonp.../../../../../src/ui-components/src/components/phone-number-input/phone-number-input.component.ts.__extends (main.bundle.js:6779) at phone-number-input.component.ts:24 at Object.../../../../../src/ui-components/src/components/phone-number-input/phone-number-input.component.ts (phone-number-input.component.ts:69) at __webpack_require__ (bootstrap 8652e46ce92ee05aa5a3:54) at Object.../../../../../src/ui-components/src/components/phone-number-input/phone-number-input.module.ts (phone-number-input.component.ts:24) at __webpack_require__ (bootstrap 8652e46ce92ee05aa5a3:54) at Object.../../../../../src/ui-components/src/ui-components.module.ts (roman-numeral.pipe.ts:10) at __webpack_require__ (bootstrap 8652e46ce92ee05aa5a3:54) at Object.../../../../../src/app/app.module.ts (app.component.ts:31) webpackJsonp.../../../../../src/ui-components/src/components/phone-number-input/phone-number-input.component.ts.__extends @ main.bundle.js:6779 (anonymous) @ phone-number-input.component.ts:24 ../../../../../src/ui-components/src/components/phone-number-input/phone-number-input.component.ts @ phone-number-input.component.ts:69 __webpack_require__ @ bootstrap 8652e46ce92ee05aa5a3:54 ../../../../../src/ui-components/src/components/phone-number-input/phone-number-input.module.ts @ phone-number-input.component.ts:24 __webpack_require__ @ bootstrap 8652e46ce92ee05aa5a3:54 ../../../../../src/ui-components/src/ui-components.module.ts @ roman-numeral.pipe.ts:10 __webpack_require__ @ bootstrap 8652e46ce92ee05aa5a3:54 ../../../../../src/app/app.module.ts @ app.component.ts:31 __webpack_require__ @ bootstrap 8652e46ce92ee05aa5a3:54 ../../../../../src/main.ts @ environment.ts:10 __webpack_require__ @ bootstrap 8652e46ce92ee05aa5a3:54 2 @ ui-components.module.ts:108 __webpack_require__ @ bootstrap 8652e46ce92ee05aa5a3:54 webpackJsonpCallBACk @ bootstrap 8652e46ce92ee05aa5a3:25 (anonymous) @ main.bundle.js:1

当遵循指定的文件和行号时,我找不到任何问题. IDE显示没有问题,编译发生没有错误.

当试图注释掉错误中提到的组件时,它只是开始提到另一个组件.

可能导致这种情况的原因以及如何调试/调查这个神秘错误？
