检测到Angular Compiler但它是错误类的一个实例

我知道这已经被问到我已经尝试过我在那里找到的所有可能的东西了.仍然无法破解它.任何帮助表示赞赏.

错误：

ERROR in ./src/main.ts
Module build Failed: Error: Angular Compiler was detected but it was an instance of the wrong class.
This likely means you have several @ngtools/webpack packages installed. You can check this with `npm ls @ngtools/webpack`,and then remove the extra copies.

我已经尝试了所有可能的想法

>删除node_module文件夹和Package.lock.json
>重新安装npm – npm安装
>尝试了npm更新

在这里任何关于失踪的帮助将非常感谢我被困在这里.

———————————

经过大量研究后,我能够通过将package.json更改为下面来解决此问题

{
  "name": "app1","dependencies": {
    "@angular/animations": "^5.2.0","@angular/cdk": "^5.2.4","@angular/material": "^5.2.4","ng2-tooltip": "0.0.7","webpack": "^2.5.1","devDependencies": {
    "@angular/cli": "~1.7.2","@angular/compiler-cli": "^5.2.0","@angular/language-service": "^5.2.0","@types/jasmine": "~2.8.3","@types/jasminewd2": "~2.0.2","@types/node": "~6.0.60","codelyzer": "^4.0.1","jasmine-core": "~2.8.0","karma": "~2.0.0","karma-coverage-istanbul-reporter": "^1.2.1","karma-jasmine": "~1.1.0","protractor": "~5.1.2","ts-node": "~4.1.0","tslint": "~5.9.1","typescript": "~2.5.3"
  }
}

但仍然有一个问题说.

ERROR in No NgModule Metadata found for 'AppModule'.
