angular - 在 Angular CLI中出现构建错误:无法重新声明块作用域变量'ngDevMode'

我的角度应用程序中出现了奇怪的构建错误。谁能指出我做错了什么？我正在尝试使用adal.js angular包集成azure ad身份验证。我用adal-angular5来做这个。
cli命令：ng serve
node_modules/@angular/core/src/render3/ng_dev_mode.d.ts（9,11）中出错：错误ts2451:无法重新声明块范围变量“ngdevmode”。
node_modules/adal-angular5/node_modules/@angular/core/src/render3/ng_dev_mode.d.ts（9,11）：错误ts2451:无法重新声明块范围变量“ngdevmode”。
与ng build --prod一起使用时
@angular\common\http\http.ts（62,2）中的错误：“httpclient”的模板编译期间出错
decorators不支持函数调用，但在“injectable”中调用了“_makedecorator”
“injectable”调用“makedecorator”。
node_modules/@angular/core/src/render3/ng_dev_mode.d.ts（9,11）：错误ts2451:无法重新声明块范围变量“ngdevmode”。
node_modules/adal-angular5/node_modules/@angular/core/src/render3/ng_dev_mode.d.ts（9,11）：错误ts2451:无法重新声明块范围变量“ngdevmode”。
这是我的角度版本细节

我的app.moudle.ts供参考：

import { AuthService } from './services/auth.service';
import { AuthGuardService } from './services/auth-gurad.service';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { AppComponent } from './app.component';
import { ProtectedComponent } from './protected/protected.component';
import { AuthCallbackComponent } from './auth-callback/auth-
callback.component';
import { Adal5Service, Adal5HTTPService } from 'adal-angular5';
import { HttpClient } from '@angular/common/http';
const routes: Routes = [
{
   path:'',
   children: []
},
{
   path:'protected',
   component:ProtectedComponent,
   canActivate: [AuthGuardService]
},
{
   path:'auth-callback',
   component:AuthCallbackComponent
}
];

@NgModule({
declarations: [
  AppComponent,
  ProtectedComponent,
  AuthCallbackComponent
 ],
 imports: [
    BrowserModule,
    RouterModule.forRoot(routes)
 ],
 exports: [RouterModule],
 providers: [AuthGuardService, AuthService, Adal5Service,{
 provide:Adal5HTTPService, useFactory:Adal5HTTPService.factory, deps:
 [HttpClient, Adal5Service] } ],
 bootstrap: [AppComponent]
 })

 export class AppModule { }

这是我的tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
  "baseUrl": "./",
  "outDir": "./dist/out-tsc",
  "sourceMap": true,
  "declaration": false,
  "module": "es2015",
  "moduleResolution": "node",
  "emitDecoratorMetadata": true,
  "experimentalDecorators": true,
  "target": "es5",
  "typeRoots": [
     "node_modules/@types"
  ],
  "lib": [
  "es2017",
  "dom"
   ]
  }
 }

如果需要更多的参考，请告诉我。

最佳答案

看起来您试图在项目中使用Angular6，但adal-angular5取决于Angular5。因此，安装了Angular5和Angular6，它们的类型定义相互冲突；您在运行时也可能遇到问题。请将项目切换到Angular5或尝试adal-angular4，它应该支持Angular4和更新版本。
