Question

我现在正在将我的项目从Angular版本5.2升级到Angular版本7.2。我运行了以下命令：

将所有角度包package.json升级到〜7.2.0
运行升级@ angular / cli
运行升级@ angular / core
运行测试并收到错误消息：

Chrome 68.0.3440（Windows 8.1.0.0）NdvAction ndv !!!!失败错误：无法解析ApplicationModule的所有参数：（？）。在语法错误node_modules/@angular/compiler/fesm5/compiler.js：2426：1）在CompileMetadataResolver.push ../ node_modules/@angular/compiler/fesm5/compiler.js.CompileMetadataResolver._getDependenciesMetadata node_modules / @ angular / com /compiler.js:18979:1）位于CompileMetadataResolver.push ../ node_modules/@angular/compiler/fesm5/compiler.js.CompileMetadataResolver._getTypeMetadata node_modules/@angular/compiler/fesm5/compiler.js：18872：1） CompileMetadataResolver.push ../ node_modules/@angular/compiler/fesm5/compiler.js.CompileMetadataResolver.getNgModuleMetadata node_modules/@angular/compiler/fesm5/compiler.js：18740：1）在CompileMetadataRenoder.push。 /compiler/fesm5/compiler.js.CompileMetadataResolver.getNgModuleSummary node_modules/@angular/compiler/fesm5/compiler.js：18550：1）位于http://localhost:9876/_karma_webpack_/webpack:/node_modules/@angular/compiler/fesm5/compiler.js:18664:1，位于Array.forEach（），位于CompileMetadataResolver.push ..// node_modules @ angular / compiler / fesm5 / compiler.js.CompileMetadataResolver.getNgModuleMetadata node_modules / @ angular / compiler / fesm5 / compiler.js：18652：1），位于CompileMetadataResolver.push ../ node_modules/@angular/compiler/fesm5/compiler.js.CompileMetadataResolver.getNgModuleSummary node_modules/@angular/compiler/fesm5/compiler.js： Chrome 68.0.3440（Windows 8.1.0.0）：执行395之1（1失败）（跳过394）错误（0.527秒/0.038秒）

我可以在项目本身上重现该问题，不能在一个空项目中重现该问题，我创建了一个空服务：

import { Injectable } from '@angular/core';

@Injectable()
export class NdvAction {
}

有空的测试用例：

import { TestBed, inject } from '@angular/core/testing';
import { NdvAction } from './ndv.action';

fdescribe('NdvAction', () => {
  let target: NdvAction;

  beforeEach(() => {
    TestBed.configureTestingModule({
      providers: [NdvAction]
    });
  });

  beforeEach(inject([NdvAction],
    (service: NdvAction) => {
      target = service;
    }));

  it('ndv!!!!', () => {});
});

我得到了错误，当我用inject（[NdvAction]部分删除了beforeEach时，错误消失了。知道我在做什么错吗？如果您需要更多详细信息，请告诉我，以便我补充。我的package.json看起来像这样：
